Description
本發明係有關於一種適配器及電子系統,特別是一種具有低待機損耗之適配器及具有低待機損耗之電子系統。 The present invention relates to an adapter and an electronic system, and more particularly to an adapter having low standby loss and an electronic system having low standby loss.
適配器(adapter)是一種常見的電子裝置;通常,適配器係用以接收並轉換交流電源成為直流電源,並輸出直流電源至後端的負載裝置以驅動負載裝置,因此適配器在電子領域來說非常的重要。 An adapter is a common electronic device; usually, an adapter is used to receive and convert an AC power source into a DC power source, and output a DC power source to a load device at the back end to drive the load device, so the adapter is very important in the electronic field. .
一般而言,當適配器沒有連接至負載裝置時,適配器會停止轉換及輸出電力而進入待機模式。在待機模式下,為了讓適配器能夠較快地進入到可工作狀態,適配器內部電路仍然會有待機損耗(standby loss),將會造成能源的浪費。另外,當適配器重新連接至負載裝置時,適配器必須能夠迅速且準確地自動重置啟動(auto re-start)以供電予後端的負載裝置。 In general, when the adapter is not connected to the load device, the adapter stops switching and outputs power and enters standby mode. In standby mode, in order to allow the adapter to enter the working state faster, the internal circuit of the adapter still has standby loss, which will cause waste of energy. In addition, when the adapter is reconnected to the load device, the adapter must be able to automatically and automatically reset the auto re-start to supply power to the load device at the back end.
然而,目前適配器的缺點為待機損耗過高而浪費能源,且當適配器重新連接負載裝置的自動重置啟動往往不夠迅速準確,此為極待解決之課題。 However, the current disadvantage of the adapter is that the standby loss is too high and the energy is wasted, and the automatic reset start of the adapter when the adapter is reconnected is often not fast enough and accurate, which is an extremely problem to be solved.
為改善上述習知技術之缺點,本發明之目的在於提供一種具有低待機損耗之適配器。 In order to improve the above disadvantages of the prior art, it is an object of the present invention to provide an adapter having low standby loss.
為改善上述習知技術之缺點,本發明之又一目的在於提供一種具有低待機損耗之電子系統。 In order to improve the above disadvantages of the prior art, it is still another object of the present invention to provide an electronic system having low standby loss.
為達成本發明之上述目的,本發明之具有低待機損耗之適配器用以供電給負載裝置,該適配器包含:一整流單元;一功率因素校正單元,電連接該整流單元,並送出一第一電壓;一待機電路,電連接該功率因素校正單元,用以將該第一電壓轉換成一第二電壓及一第三電壓;一負載插接偵測電路,電連接該待機電路,並接收該第二電壓;一第一電源轉換電路,電連接該功率因素校正單元,具有一第一輸出端與一第一接地端,該第一接地端電連接該負載插接偵測電路;一第二電源轉換電路,電連接該功率因素校正單元,具有一第二輸出端與一第二接地端,該第二接地端電連接該負載插接偵測電路,且該第一接地端和該第二接地端連接到不同的接地;及一輔助電壓控制電路,電連接該待機電路、該第一電源轉換電路及該第二電源轉換電路,並接收該第三電壓。其中,當負載裝置不連接該適配器時,該第一接地端與該第二接地端的電壓不同,使得該負載插接偵測電路不送出一第一訊號;該輔助電壓控制電路沒有接收到該第一訊號,使得該輔助電壓控制電路不驅動該第一電源轉換電路及該第二電源轉換電路,因此該第一電源轉換電路及該第二電源轉換電路不將該第一電壓轉換成一第一輸出電壓和一第二輸出電壓。其中,當負載裝置連接該適配器時,該第一接地端與該第二接地端形成短路,使得該負載插接偵測電路導通並送出該第一訊號,該輔助電壓控制電路接收到該第一訊號後導通,並送出一第四電壓以驅動該第一電源轉換電路及該第二電源轉換電路,使得該第一電源轉換電路及該第二電源轉換電路開始將該第一電壓轉換成該第一輸出電壓和該第二輸出電壓。 In order to achieve the above object of the present invention, an adapter with low standby loss of the present invention is used for supplying power to a load device. The adapter includes: a rectifying unit; a power factor correcting unit electrically connecting the rectifying unit and sending a first voltage a standby circuit electrically connected to the power factor correction unit for converting the first voltage into a second voltage and a third voltage; a load plug detection circuit electrically connecting the standby circuit and receiving the second a first power conversion circuit electrically connected to the power factor correction unit has a first output end and a first ground end, the first ground end is electrically connected to the load plug detection circuit; and a second power conversion The circuit is electrically connected to the power factor correcting unit, and has a second output end and a second ground end, wherein the second ground end is electrically connected to the load plug detecting circuit, and the first ground end and the second ground end Connected to different grounding; and an auxiliary voltage control circuit electrically connecting the standby circuit, the first power conversion circuit and the second power conversion circuit, and receiving the third Pressure. Wherein, when the load device is not connected to the adapter, the voltage of the first ground end and the second ground end is different, so that the load plug detecting circuit does not send a first signal; the auxiliary voltage control circuit does not receive the first a signal, the auxiliary voltage control circuit does not drive the first power conversion circuit and the second power conversion circuit, so the first power conversion circuit and the second power conversion circuit do not convert the first voltage into a first output Voltage and a second output voltage. When the load device is connected to the adapter, the first ground end and the second ground end form a short circuit, so that the load plug detection circuit is turned on and sends out the first signal, and the auxiliary voltage control circuit receives the first After the signal is turned on, and a fourth voltage is sent to drive the first power conversion circuit and the second power conversion circuit, so that the first power conversion circuit and the second power conversion circuit start to convert the first voltage into the first An output voltage and the second output voltage.
為達成本發明之上述又一目的,本發明之具有低待機損耗之電子系統包含如上所述之適配器及一負載裝置。其中,當該負載裝置連接該適配器時,該第一接地端與該第二接地端形成短路,使得該適配器輸出電壓至該負載裝置。 In order to achieve the above-described still further object of the present invention, an electronic system having low standby loss of the present invention includes the adapter and a load device as described above. Wherein, when the load device is connected to the adapter, the first ground end forms a short circuit with the second ground end, so that the adapter outputs a voltage to the load device.
本發明之功效在於當負載裝置沒有連接適配器時,因為不同的電源轉換電路的接地端的電壓不同,可使電源轉換電路不被驅動而不工作不耗能,藉此使得適配器的待機損耗極低;另一方面,當負載裝置連接適配器時,不同的電源轉換電路的接地端形成短路,使該些接地端的電壓相同,可使電源轉換電路被驅動而供電予負載裝置,藉此可使適配器的自動重置啟動迅速且準確。 The effect of the invention is that when the load device is not connected to the adapter, because the voltages of the ground terminals of different power conversion circuits are different, the power conversion circuit can be driven without being operated without energy consumption, thereby making the standby loss of the adapter extremely low; On the other hand, when the load device is connected to the adapter, the ground terminals of different power conversion circuits form a short circuit, so that the voltages of the ground terminals are the same, so that the power conversion circuit can be driven to supply power to the load device, thereby enabling the automatic adapter The reset is quick and accurate.

The current balancing unit 100 is electrically connected to the first power conversion circuit 30, the first output terminal 306, the second power conversion circuit 40, and the second output terminal 406.
該功率因素校正單元120送出一第一電壓HV至該待機電路80、該第一電源轉換電路30及該第二電源轉換電路40;該待機電路80係用以將該第一電壓HV轉換成一第二電壓VSTB及一第三電壓VAUX;該待機電路80傳送該第二電壓VSTB至該負載插接偵測電路20;該待機電路80傳送該第三電壓VAUX至該 輔助電壓控制電路50;該負載插接偵測電路20接收該第二電壓VSTB;該輔助電壓控制電路50接收該第三電壓VAUX。 The power factor correction unit 120 sends a first voltage HV to the standby circuit 80, the first power conversion circuit 30, and the second power conversion circuit 40. The standby circuit 80 is configured to convert the first voltage HV into a first a second voltage VSTB and a third voltage VAUX; the standby circuit 80 transmits the second voltage VSTB to the load plug detecting circuit 20; the standby circuit 80 transmits the third voltage VAUX to the The auxiliary voltage control circuit 50; the load plug detecting circuit 20 receives the second voltage VSTB; the auxiliary voltage control circuit 50 receives the third voltage VAUX.
首先,本發明之技術特徵之一為:藉由印刷電路板佈線與製作技術,將該第一接地端302與該第二接地端402連接到不同的接地,使得該第一接地端302的電壓不等於該第二接地端402的電壓;只有當該負載裝置60連接該具有低待機損耗之適配器10時,該第一接地端302與該第二接地端402會形成短路,使得該第一接地端302的電壓等於該第二接地端402的電壓。茲詳述如下: 當該負載裝置60不連接該具有低待機損耗之適配器10時,該第一接地端302的電壓不等於該第二接地端402的電壓,使得該負載插接偵測電路20不送出一第一訊號(容後詳述);該輔助電壓控制電路50沒有接收到該第一訊號,使得該輔助電壓控制電路50不驅動該第一電源轉換電路30及該第二電源轉換電路40,因此該第一電源轉換電路30及該第二電源轉換電路40不會將該第一電壓HV轉換成一第一輸出電壓Vout1和一第二輸出電壓Vout2。 First, one of the technical features of the present invention is that the first ground terminal 302 and the second ground terminal 402 are connected to different grounds by a printed circuit board wiring and fabrication technique, so that the voltage of the first ground terminal 302 is Not equal to the voltage of the second grounding terminal 402; only when the load device 60 is connected to the adapter 10 having low standby loss, the first grounding terminal 302 and the second grounding terminal 402 form a short circuit, so that the first grounding The voltage at terminal 302 is equal to the voltage at the second ground terminal 402. Details are as follows: When the load device 60 is not connected to the adapter 10 having low standby loss, the voltage of the first ground terminal 302 is not equal to the voltage of the second ground terminal 402, so that the load plug detection circuit 20 does not send a first a signal (described in detail later); the auxiliary voltage control circuit 50 does not receive the first signal, so that the auxiliary voltage control circuit 50 does not drive the first power conversion circuit 30 and the second power conversion circuit 40, so the first A power conversion circuit 30 and the second power conversion circuit 40 do not convert the first voltage HV into a first output voltage Vout1 and a second output voltage Vout2.
當負載裝置沒有連接適配器時,因為不同的電源轉換電路的接地端的電壓不同,可使電源轉換電路不被驅動而不工作不耗能,藉此降低適配器的待機損耗(可小於0.5瓦特)。 When the load device is not connected to the adapter, because the voltage of the ground of the different power conversion circuits is different, the power conversion circuit can be driven without being operated without energy consumption, thereby reducing the standby loss of the adapter (which can be less than 0.5 watts).
當該負載裝置60連接該具有低待機損耗之適配器10時,該第一接地端302與該第二接地端402形成短路(即,該第一接地端302的電壓等於該第二接地端402的電壓),使得該負載插接偵測電路20導通並送出該第一訊號(容後詳述);該輔助電壓控制電路50接收到該第一訊號後導通,並送出一第四電壓VDD以驅動該第一電源轉換電路30及該第二電源轉換電路40,使得該第一電源轉換電路30及該第二電源轉換電路40開始將該第一電壓HV轉換成該第一輸出電壓Vout1和該第二輸出電壓Vout2以傳送至該負載裝置60。 When the load device 60 is connected to the adapter 10 having low standby loss, the first ground terminal 302 forms a short circuit with the second ground terminal 402 (ie, the voltage of the first ground terminal 302 is equal to the second ground terminal 402). The voltage is applied to enable the load plug detection circuit 20 to turn on and send the first signal (described in detail later); the auxiliary voltage control circuit 50 is turned on after receiving the first signal, and sends a fourth voltage VDD to drive The first power conversion circuit 30 and the second power conversion circuit 40 cause the first power conversion circuit 30 and the second power conversion circuit 40 to start converting the first voltage HV into the first output voltage Vout1 and the first The two output voltages Vout2 are transmitted to the load device 60.
當負載裝置連接適配器時,不同的電源轉換電路的接地端形成短路,可使電源轉換電路被驅動而供電予負載裝置,藉此可使適配器的自動重置啟動迅速且準確。 When the load device is connected to the adapter, the ground terminal of the different power conversion circuit forms a short circuit, so that the power conversion circuit can be driven to supply power to the load device, thereby enabling the automatic reset of the adapter to be started quickly and accurately.
該電流平衡單元100偵測該第一輸出端306與該第二輸出端406的電流值,並送出一第二訊號給該第一電源轉換電路30與該第二電源轉換電路40。 The current balancing unit 100 detects the current value of the first output terminal 306 and the second output terminal 406, and sends a second signal to the first power conversion circuit 30 and the second power conversion circuit 40.
在本發明的另一實施態樣中,具有低待機損耗之電子系統可包含前述具有低待機損耗之適配器10加上前述負載裝置60;當該負載裝置60未連接該適配器10時,該第一接地端302與該第二接地端402的電壓不同,使得該適配器10不會輸出電壓至該負載裝置60;當該負載裝置60連接該適配器10時,該第一接地端302與該第二接地端402形成短路,使得該適配器10輸出電壓至該負載裝置60。 In another embodiment of the present invention, an electronic system having low standby loss may include the aforementioned adapter 10 having low standby loss plus the aforementioned load device 60; when the load device 60 is not connected to the adapter 10, the first The voltage of the ground terminal 302 and the second ground terminal 402 are different, so that the adapter 10 does not output a voltage to the load device 60; when the load device 60 is connected to the adapter 10, the first ground terminal 302 and the second ground Terminal 402 forms a short circuit such that adapter 10 outputs a voltage to the load device 60.
請參考圖5,其係為本發明之負載插接偵測電路之一具體實施例電路圖。該具有低待機損耗之適配器10更包含一第一連接器70;該負載插接偵測電路20包含一第一電晶體開關202、一光耦合器發送端214、一第二電晶體開關216、一第一電阻204、一第二電阻206、一第三電阻208、一第一電容210及一第四電阻212。 Please refer to FIG. 5 , which is a circuit diagram of a specific embodiment of the load plug detection circuit of the present invention. The adapter 10 having a low standby loss further includes a first connector 70. The load plug detection circuit 20 includes a first transistor switch 202, an optocoupler transmitting end 214, and a second transistor switch 216. A first resistor 204, a second resistor 206, a third resistor 208, a first capacitor 210 and a fourth resistor 212.
該第一電晶體開關202電性連接該第一電源轉換電路30、該第一電阻204、該第二電阻206、該第三電阻208、該第一電容210、該第一連接器70及該第二電晶體開關216;該光耦合器發送端214電性連接該第二電晶體開關216及該第四電阻212;該待機電路80電性連接該第一電阻204、該第三電阻208及該第四電阻212;該第二電源轉換電路40電性連接該第二電阻206、該第一電容210、該第一電晶體開關202、該第二電晶體開關216及該第一連接器70。 The first transistor switch 202 is electrically connected to the first power conversion circuit 30, the first resistor 204, the second resistor 206, the third resistor 208, the first capacitor 210, the first connector 70, and the a second transistor switch 216; the optocoupler transmitting end 214 is electrically connected to the second transistor switch 216 and the fourth resistor 212; the standby circuit 80 is electrically connected to the first resistor 204, the third resistor 208, and The fourth resistor 212 is electrically connected to the second resistor 206, the first capacitor 210, the first transistor switch 202, the second transistor switch 216, and the first connector 70. .
再者,請同時參考圖1;當該負載裝置60不連接該具有低待機損耗之適配器10時,由於該第一接地端302與該第二接地端402連接於不同的接 地,因此該第一接地端302和該第二接地端402的電壓不同,使得該第一電晶體開關202導通,進而使得該第二電晶體開關216不導通,再進而使得該光耦合器發送端214不導通,該光耦合器發送端214不送出該第一訊號(容後詳述)。 Furthermore, please refer to FIG. 1 at the same time; when the load device 60 is not connected to the adapter 10 with low standby loss, the first ground terminal 302 and the second ground terminal 402 are connected to different connections. Therefore, the voltages of the first grounding terminal 302 and the second grounding terminal 402 are different, so that the first transistor switch 202 is turned on, so that the second transistor switch 216 is not turned on, and then the optical coupler is sent. The terminal 214 is not turned on, and the optical coupler transmitting end 214 does not send the first signal (described in detail later).
當該負載裝置60連接該具有低待機損耗之適配器10時,該第一接地端302與該第二接地端402形成短路,因此該第一接地端302和該第二接地端402的電壓相同,使得該第一電晶體開關202不導通,進而使得該第二電壓VSTB導通該第二電晶體開關216後再導通該光耦合器發送端214(即,該第二電壓VSTB使得該第二電晶體開關216及該光耦合器發送端214導通),該光耦合器發送端214送出該第一訊號(容後詳述)。 When the load device 60 is connected to the adapter 10 having low standby loss, the first ground terminal 302 and the second ground terminal 402 form a short circuit, so that the voltages of the first ground terminal 302 and the second ground terminal 402 are the same. The first transistor switch 202 is not turned on, so that the second voltage VSTB turns on the second transistor switch 216 and then turns on the photocoupler transmitting end 214 (ie, the second voltage VSTB makes the second transistor The switch 216 and the optocoupler transmitting end 214 are turned on, and the optocoupler transmitting end 214 sends the first signal (described in detail later).
請參考圖6,其係為本發明之輔助電壓控制電路、第一電源轉換電路及第二電源轉換電路之一具體實施例電路圖。 Please refer to FIG. 6, which is a circuit diagram of a specific embodiment of the auxiliary voltage control circuit, the first power conversion circuit, and the second power conversion circuit of the present invention.
該輔助電壓控制電路50包含一光耦合器接收端504、一輔助電壓端電晶體開關506、一齊納二極體508及一輔助電壓端電阻510。該輔助電壓端電晶體開關506電性連接該待機電路80、該光耦合器接收端504、該輔助電壓端電阻510、該齊納二極體508、該第一電源轉換電路30及該第二電源轉換電路40。 The auxiliary voltage control circuit 50 includes an optocoupler receiving end 504, an auxiliary voltage terminal transistor switch 506, a Zener diode 508 and an auxiliary voltage terminal resistor 510. The auxiliary voltage terminal transistor switch 506 is electrically connected to the standby circuit 80, the optocoupler receiving end 504, the auxiliary voltage terminal resistor 510, the Zener diode 508, the first power conversion circuit 30, and the second Power conversion circuit 40.
如前所述,當該負載裝置60不連接該具有低待機損耗之適配器10時,該第一接地端302與該第二接地端402的電壓不相同,該光耦合器發送端214不送出該第一訊號。此時,該光耦合器接收端504沒有接收到該第一訊號而不導通,使得該輔助電壓端電晶體開關506不導通,該輔助電壓端電晶體開關506不送出該第四電壓VDD。亦即,該輔助電壓控制電路50不驅動該第一電源轉換電路30及該第二電源轉換電路40,因此該第一電源轉換電路30及該第二電源轉換電路40不將該第一電壓HV轉換成一第一輸出電壓Vout1和一第二輸出電壓Vout2。 As described above, when the load device 60 is not connected to the adapter 10 having low standby loss, the voltage of the first ground terminal 302 and the second ground terminal 402 are different, and the optical coupler transmitting end 214 does not send the The first signal. At this time, the optocoupler receiving end 504 does not receive the first signal and is not turned on, so that the auxiliary voltage terminal transistor switch 506 is not turned on, and the auxiliary voltage terminal transistor switch 506 does not send the fourth voltage VDD. That is, the auxiliary voltage control circuit 50 does not drive the first power conversion circuit 30 and the second power conversion circuit 40, so the first power conversion circuit 30 and the second power conversion circuit 40 do not use the first voltage HV. The signal is converted into a first output voltage Vout1 and a second output voltage Vout2.
當負載裝置沒有連接適配器時,因為不同的電源轉換電路的接地端的電壓不同,可使電源轉換電路不被驅動而不工作不耗能,藉此降低適配器的待機損耗(可小於0.5瓦特)。 When the load device is not connected to the adapter, because the voltage of the ground of the different power conversion circuits is different, the power conversion circuit can be driven without being operated without energy consumption, thereby reducing the standby loss of the adapter (which can be less than 0.5 watts).
當該負載裝置60連接該具有低待機損耗之適配器10時,該第一接地端302與該第二接地端402形成短路,該光耦合器發送端214送出該第一訊號。該光耦合器接收端504接收到該第一訊號後導通,使得該第三電壓VAUX導通該輔助電壓端電晶體開關506,該輔助電壓端電晶體開關506送出該第四電壓VDD。亦即,該輔助電壓控制電路50送出該第四電壓VDD以驅動該第一電源轉換電路30及該第二電源轉換電路40,使得該第一電源轉換電路30及該第二電源轉換電路40開始將該第一電壓HV轉換成該第一輸出電壓Vout1和該第二輸出電壓Vout2以傳送至該負載裝置60。在該輔助電壓端電晶體開關506導通之後,利用該齊納二極體508的電氣特性以箝制該第三電壓VAUX以形成並提供該第四電壓VDD。 When the load device 60 is connected to the adapter 10 having low standby loss, the first ground terminal 302 forms a short circuit with the second ground terminal 402, and the optical coupler transmitting end 214 sends the first signal. The optocoupler receiving end 504 is turned on after receiving the first signal, so that the third voltage VAUX is turned on by the auxiliary voltage terminal transistor switch 506, and the auxiliary voltage terminal transistor switch 506 sends the fourth voltage VDD. That is, the auxiliary voltage control circuit 50 sends the fourth voltage VDD to drive the first power conversion circuit 30 and the second power conversion circuit 40, so that the first power conversion circuit 30 and the second power conversion circuit 40 start. The first voltage HV is converted into the first output voltage Vout1 and the second output voltage Vout2 for transmission to the load device 60. After the auxiliary voltage terminal transistor switch 506 is turned on, the third voltage VAUX is clamped by the electrical characteristics of the Zener diode 508 to form and provide the fourth voltage VDD.
當負載裝置連接適配器時,不同的電源轉換電路的接地端形成短路,可使電源轉換電路被驅動而供電予負載裝置,藉此可使適配器的自動重置啟動迅速且準確。 When the load device is connected to the adapter, the ground terminal of the different power conversion circuit forms a short circuit, so that the power conversion circuit can be driven to supply power to the load device, thereby enabling the automatic reset of the adapter to be started quickly and accurately.
