Power to the electronic system PS.
隔離單元58電連接於電源管理器56及控制器52,用以隔離地將電源管理器56發出的信號傳遞至控制器52,此外,隔離單元58也可以隔離地將控制器52發出的信號傳遞至電源管理器56。 The isolation unit 58 is electrically connected to the power manager 56 and the controller 52 for isolating the signal from the power manager 56 to the controller 52. In addition, the isolation unit 58 can also transmit the signal from the controller 52 in isolation. To the power manager 56.
在實際操作時,當開關元件54關閉時,則由交/直流電源轉換模組50之電力輸出端Vdc輸出的直流電力無法通過主電源輸出端V1及V2傳遞至電子系統PS;反之,當開關元件54開啟時,交/直流電源轉換模組50之電力輸出端Vdc輸出的直流電力可以通過主電源輸出端V1及V2傳遞至電子系統PS。另外,不論開關元件54是開啟或關閉,待機電源輸出端Vsb都會輸出電力至電子系統PS。 In actual operation, when the switching element 54 is turned off, the DC power outputted by the power output terminal Vdc of the AC/DC power conversion module 50 cannot be transmitted to the electronic system PS through the main power output terminals V1 and V2; When the component 54 is turned on, the DC power output from the power output terminal Vdc of the AC/DC power conversion module 50 can be transmitted to the electronic system PS through the main power output terminals V1 and V2. In addition, the standby power output terminal Vsb outputs power to the electronic system PS regardless of whether the switching element 54 is turned on or off.
配合參閱第四圖,為本揭示內容第一實施方式之線性控制模組之電路圖。為了方便說明,第四圖同時繪示出開關元件54、主電源輸出電阻器Ro1及Ro2、主電源輸出端V1及V2、待機電源輸出端Vsb及待機電源輸出電阻器Ro3。同時,第四圖也繪示出交/直流轉換模組50的電力輸出端Vdc,以及電源管理器56的控制信號輸出端Sin。在本實施方式中,開關元件54以P型金屬氧化物半導體場效電晶體(Metal-Oxide-Semiconductor Field-Effect Transistor,MOSFET)作為說明範例,實際實施時則不以此為限。 Referring to the fourth figure, a circuit diagram of a linear control module according to a first embodiment of the disclosure is shown. For convenience of explanation, the fourth figure simultaneously shows the switching element 54, the main power output resistors Ro1 and Ro2, the main power output terminals V1 and V2, the standby power output terminal Vsb, and the standby power output resistor Ro3. Meanwhile, the fourth figure also shows the power output terminal Vdc of the AC/DC converter module 50 and the control signal output terminal Sin of the power manager 56. In the present embodiment, the switching element 54 is exemplified by a P-type metal-oxide-semiconductor field-effect transistor (MOSFET), and the actual implementation is not limited thereto.
線性控制模組7包含一控制開關Q1、一第一電阻器R1、一電容器C1及一第二電阻器RS,控制開關Q1電連接於控制信號 輸出端Sin,第一電阻器R1電連接於控制開關Q1,電容器C1電連接於交/直流轉換模組50的電力輸出端Vdc及開關元件54,第二電阻器RS電連接於電容器C1、第一電阻器R1及開關元件54,且並聯於電容器C1。 The linear control module 7 includes a control switch Q1, a first resistor R1, a capacitor C1 and a second resistor RS. The control switch Q1 is electrically connected to the control signal. The output terminal Sin, the first resistor R1 is electrically connected to the control switch Q1, the capacitor C1 is electrically connected to the power output terminal Vdc of the AC/DC converter module 50 and the switching element 54, and the second resistor RS is electrically connected to the capacitor C1 A resistor R1 and a switching element 54 are connected in parallel to the capacitor C1.
在本實施方式中,控制開關Q1為N型金屬氧化物半導體場效電晶體,且控制開關Q1的閘級電連接於控制信號輸出端Sin,控制開關Q1的汲極電連接於第一電阻器R1,控制開關Q1的源極電連接於地端。實際實施時,控制開關Q1也可以是其他具有切換功能的電子元件。 In this embodiment, the control switch Q1 is an N-type metal oxide semiconductor field effect transistor, and the gate of the control switch Q1 is electrically connected to the control signal output terminal Sin, and the drain of the control switch Q1 is electrically connected to the first resistor. R1, the source of the control switch Q1 is electrically connected to the ground. In actual implementation, the control switch Q1 may also be other electronic components having a switching function.
同時配合參閱第三圖及第四圖,當電子系統PS啟動時,電源管理器56的信號輸入端PS_On會接收到電子系統PS送出的啟動信號。之後,電源管理器56的控制信號輸出端Sin送出一控制信號至線性控制模組7的控制開關Q1,以驅使控制開關Q1導通。當控制開關Q1導通,電容器C1開始充電,則開關元件54閘極與源極之間的電壓值升高。其次,當控制開關Q1導通時,第一電阻器R1及第二電阻器R2構成分壓電路,故藉由適當地配置第一電阻器R1及第二電阻器RS的電阻值,就可以控制開關元件54閘極與源極之間的電壓差值,以控制開關元件54導通,同時還能避免開關元件54因承受過大電壓而損壞。當開關元件54導通,主電源輸出端V1及V2輸出電力至電子系統PS。 At the same time, referring to the third figure and the fourth figure, when the electronic system PS is activated, the signal input terminal PS_On of the power manager 56 receives the start signal sent by the electronic system PS. Thereafter, the control signal output terminal Sin of the power manager 56 sends a control signal to the control switch Q1 of the linear control module 7 to drive the control switch Q1 to be turned on. When the control switch Q1 is turned on and the capacitor C1 starts to be charged, the voltage value between the gate and the source of the switching element 54 rises. Next, when the control switch Q1 is turned on, the first resistor R1 and the second resistor R2 constitute a voltage dividing circuit, so that the resistance values of the first resistor R1 and the second resistor RS can be appropriately configured to control The voltage difference between the gate and the source of the switching element 54 controls the switching element 54 to be turned on, while also preventing the switching element 54 from being damaged by excessive voltage. When the switching element 54 is turned on, the main power output terminals V1 and V2 output power to the electronic system PS.
藉由電容器C1、第一電阻器R1及第二電阻器RS的使用,可 以使得開關元件54源極及閘極兩端的電壓差值呈平緩且線性地上升,避免開關元件54在電子系統PS啟動瞬間導通,如此一來,就可以避免電力輸出端Vdc輸出的電壓值在電子系統PS啟動時發生瞬間驟降的情形。 By using capacitor C1, first resistor R1 and second resistor RS, In order to make the voltage difference between the source and the gate of the switching element 54 rise gently and linearly, the switching element 54 is prevented from being turned on at the instant of starting the electronic system PS, so that the voltage value outputted by the power output terminal Vdc can be avoided. An occasional sudden dip occurs when the electronic system PS starts up.
配合參閱第六圖,實線所示為對應第三圖之電力輸出端Vdc輸出之電壓值,虛線所示為對應第三圖之主電源輸出端V1及V2之電壓值。相較於第二圖,第六圖所示之電力輸出端Vdc輸出的電壓在電子系統PS啟動的瞬間並沒有發生瞬間驟降的問題,可以提供電源供應系統3使用的穩定度,避免電源供應系統3因電壓驟降而產生誤動作。是故,本揭示內容之線性控制模組7確實可以有效地避免電力輸出端Vdc輸出的電壓值在電子系統PS啟動的瞬間發生瞬間骤降的情形。 Referring to the sixth figure, the solid line shows the voltage value corresponding to the Vdc output of the power output terminal of the third figure, and the broken line shows the voltage value corresponding to the main power output terminals V1 and V2 of the third figure. Compared with the second figure, the voltage outputted by the power output terminal Vdc shown in the sixth figure does not have an instantaneous sudden drop at the moment when the electronic system PS is started, and the stability of the power supply system 3 can be provided to avoid the power supply. System 3 malfunctions due to a sudden voltage drop. Therefore, the linear control module 7 of the present disclosure can effectively avoid the situation where the voltage value outputted by the power output terminal Vdc instantaneously drops when the electronic system PS is activated.
反之,當電子系統PS未啟動時(即電子系統PS操作於待機狀態時),電源管理器56控制信號輸出端Sin送出一控制信號至線性控制模組7的控制信號輸入端Sin。線性控制模組7接收前述控制信號,並驅使控制開關Q1截止。當控制開關Q1截止,則開關元件54截止,主電源輸出端V1及V2無電力輸出;申言之,僅待機電源輸出端Vsb輸出電力至電子系統PS。 On the contrary, when the electronic system PS is not activated (that is, when the electronic system PS is operating in the standby state), the power manager 56 controls the signal output terminal Sin to send a control signal to the control signal input terminal Sin of the linear control module 7. The linear control module 7 receives the aforementioned control signals and drives the control switch Q1 to turn off. When the control switch Q1 is turned off, the switching element 54 is turned off, and the main power output terminals V1 and V2 have no power output; in other words, only the standby power output terminal Vsb outputs power to the electronic system PS.
藉此,當電子系統PS未啟動時,主電源輸出端V1及V2不會提供電力予電子系統PS,而僅有待機電源輸出端Vsb供應電子系統PS於待機狀態時的電力,如此一來,可以有效地達到節能效果。 Thereby, when the electronic system PS is not activated, the main power output terminals V1 and V2 do not provide power to the electronic system PS, and only the standby power output terminal Vsb supplies the power of the electronic system PS in the standby state, thus, It can effectively achieve energy saving effect.
配合參閱第五圖,為本揭示內容第二實施方式之線性控制模組之電路圖。為了方便說明,第五圖同時繪示出開關元件54、主電源輸出電阻器Ro1及Ro2、主電源輸出端V1及V2、待機電源輸出端Vsb及待機電源輸出電阻器Ro3。同時,第五圖也繪示出交/直流轉換模組50的電力輸出端Vdc,以及電源管理器56的控制信號輸出端Sin。 Referring to FIG. 5, it is a circuit diagram of a linear control module according to a second embodiment of the disclosure. For convenience of explanation, the fifth diagram simultaneously shows the switching element 54, the main power output resistors Ro1 and Ro2, the main power output terminals V1 and V2, the standby power output terminal Vsb, and the standby power output resistor Ro3. Meanwhile, the fifth diagram also shows the power output terminal Vdc of the AC/DC converter module 50 and the control signal output terminal Sin of the power manager 56.
另外,本實施方式的線性控制模組7a與前述第一實施方式之線性控制模組7類似,且相同的元件標示以相同的符號。本實施方式的線性控制模組7a與第一實施方式的線性控制模組7的差異在於本實施方式的控制模組7a更包含一放電電路70。 In addition, the linear control module 7a of the present embodiment is similar to the linear control module 7 of the first embodiment described above, and the same elements are denoted by the same reference numerals. The difference between the linear control module 7a of the present embodiment and the linear control module 7 of the first embodiment is that the control module 7a of the present embodiment further includes a discharge circuit 70.
放電電路70電連接於交/直流轉換模組50的電力輸出端Vdc、控制信號輸出端Sin、電容器C1及第一電阻器R1,放電電路70用以作為電容器C1的放電路徑。 The discharge circuit 70 is electrically connected to the power output terminal Vdc of the AC/DC converter module 50, the control signal output terminal Sin, the capacitor C1 and the first resistor R1, and the discharge circuit 70 serves as a discharge path of the capacitor C1.
放電電路70包含一切換元件Q2及一第三電阻器R3,切換元件Q2電連接於交/直流轉換模組50的電力輸出端Vdc、控制信號輸出端Sin及控制開關Q1,第三電阻器R3電連接於控制開關Q1、第一電阻器R1、第二電阻器RS及電容器C1。在本實施方式中,切換元件Q2為金屬氧化物場效電晶體,切換元件Q2的閘級電連接於控制信號輸出端Sin及控制開關Q1,切換元件Q2的源極電連接於交/直流轉換模組50的電力輸出端Vdc,切換元件Q2的汲極電連接於第三電阻器R3。 The discharge circuit 70 includes a switching element Q2 and a third resistor R3. The switching element Q2 is electrically connected to the power output terminal Vdc of the AC/DC converter module 50, the control signal output terminal Sin and the control switch Q1, and the third resistor R3. It is electrically connected to the control switch Q1, the first resistor R1, the second resistor RS, and the capacitor C1. In the present embodiment, the switching element Q2 is a metal oxide field effect transistor, the gate of the switching element Q2 is electrically connected to the control signal output terminal Sin and the control switch Q1, and the source of the switching element Q2 is electrically connected to the AC/DC conversion. The power output terminal Vdc of the module 50 and the drain of the switching element Q2 are electrically connected to the third resistor R3.
放電電路70提供儲存在電容器C1中之電荷一放電路徑,以加速電容器C1完成放電動作。如此一來,可以避免電源供應系統於電子系統PS在關閉後短時間內再次啟動時,因電容器C1未完全放電而使得開關元件54無法線性地導通,導致直流電源輸出端Vdc輸出的電壓發生瞬間驟降。 The discharge circuit 70 provides a charge-discharge path stored in the capacitor C1 to accelerate the discharge operation of the capacitor C1. In this way, when the power supply system is restarted in a short time after the electronic system PS is turned off in a short time, the switching element 54 cannot be turned on linearly due to the capacitor C1 not being completely discharged, and the voltage output from the DC power output terminal Vdc is instantaneous. Dips.
此外,線性控制模組7a更包含一保護開關D,電連接於交/直流轉換模組50的電力輸出端Vdc、切換元件Q2及電容器C1。在本實施方式中,保護開關D例如(但不限制是)二極體,且保護開關D2的陽極電連接於電力輸出端Vdc,保護開關D的陰極電連接於切換元件Q2及電容器C1。當電子系統PS發生短路時,電力輸出端Vdc產生大電流輸出,保護開關D2可以避免電容器C1在電子系統PS發生短路且電力輸出端Vdc輸出大電流時無法有效地放電的情形產生,意即保護開關D2可以讓電容器C1在電子系統PS發生短路時,仍然可以透過放電電路70進行放電,因此,當電子系統PS的短路情況排除並再次啟動時,開關元件54會線性地導通,避免電力輸出端Vdc輸出的電壓值在電子系統PS啟動的瞬間發生瞬間骤降的情形。 In addition, the linear control module 7a further includes a protection switch D electrically connected to the power output terminal Vdc of the AC/DC conversion module 50, the switching element Q2, and the capacitor C1. In the present embodiment, the protection switch D is, for example but not limited to, a diode, and the anode of the protection switch D2 is electrically connected to the power output terminal Vdc, and the cathode of the protection switch D is electrically connected to the switching element Q2 and the capacitor C1. When the electronic system PS is short-circuited, the power output terminal Vdc generates a large current output, and the protection switch D2 can prevent the capacitor C1 from being effectively discharged when the electronic system PS is short-circuited and the power output terminal Vdc outputs a large current, that is, protection The switch D2 can cause the capacitor C1 to discharge through the discharge circuit 70 when the electronic system PS is short-circuited. Therefore, when the short-circuit condition of the electronic system PS is eliminated and restarted, the switching element 54 is turned on linearly to avoid the power output terminal. The voltage value of the Vdc output instantaneously drops when the electronic system PS starts.
此外,本發明更提供一種開關元件的線性導通方法,開關元件之線性導通方法適用於第四圖及第五圖所示之線性控制模組之電路架構。所述線性控制方法用來控制電連接於交/直流轉換模組次級測的開關元件,交/直流轉換模組具有一 位於次級側的電力輸出端,如第三圖所示。 In addition, the present invention further provides a linear conduction method of a switching element, and the linear conduction method of the switching element is applied to the circuit architecture of the linear control module shown in FIG. 4 and FIG. The linear control method is used to control a switching element electrically connected to the secondary measurement of the AC/DC conversion module, and the AC/DC conversion module has a Located on the secondary side of the power output, as shown in the third figure.
開關元件接收電力輸出端輸出的電力,並於電子系統PS啟動時,使主電源輸出端輸出前述電力傳遞至電子系統PS,以供應電子系統PS在啟動狀態下的操作電力;而在電子系統PS操作於待機狀態時,停止輸出主電源輸出端輸出電力至電子系統PS。 The switching element receives the power outputted by the power output terminal, and when the electronic system PS is activated, causes the main power output terminal to output the foregoing power to the electronic system PS to supply the operating power of the electronic system PS in the activated state; and in the electronic system PS When operating in the standby state, the output of the main power output output power to the electronic system PS is stopped.
此開關元件之線性控制方法用來控制開關元件54的開關狀態,使開關元件54呈現線性開啟,使開關元件54操作於安全操作區域(safe operating area),進而避免開關元件54過熱而損毀。所述開關元件54之線性控制方法首先提供一驅動電壓,並依時提供複數脈衝寬度調變(Pulse Width Modulation)控制信號予開關元件54。切換該等脈衝寬度調變信號的工作週期,使脈衝寬度調變信號的工作週期係依時序由0%增加至100%,如第七圖所示,使驅動電壓呈現線性地增加,藉以驅使開關元件54線性地導通。在本實施方式中,控制信號的工作週期由0%增加至100%的時間約為20毫秒(ms)。 The linear control method of the switching element is used to control the switching state of the switching element 54, causing the switching element 54 to be linearly opened, so that the switching element 54 operates in a safe operating area, thereby preventing the switching element 54 from being overheated and damaged. The linear control method of the switching element 54 first provides a driving voltage and provides a plurality of Pulse Width Modulation control signals to the switching element 54 in time. Switching the duty cycle of the pulse width modulation signals, so that the duty cycle of the pulse width modulation signal is increased from 0% to 100% according to the timing, as shown in the seventh figure, the driving voltage is linearly increased, thereby driving the switch Element 54 is turned on linearly. In the present embodiment, the time period during which the duty cycle of the control signal is increased from 0% to 100% is about 20 milliseconds (ms).
然以上所述者,僅為本發明揭示內容之較佳實施例,當不能限定本發明揭示內容實施之範圍,即凡依本發明申請專利範圍所作之均等變化與修飾等,皆應仍屬本發明之專利涵蓋範圍意圖保護之範疇。 However, the above description is only a preferred embodiment of the present disclosure, and the scope of the disclosure of the present invention is not limited thereto, that is, the equivalent changes and modifications made by the scope of the present invention should remain the same.
