Description
本創作係有關於一種電源供應器，特別是一種可變輸出電源供應器。This creation is about a power supply, especially a variable output power supply.
電源供應器是一種常見的電子裝置，藉以提供後端負載或電器用品電源。目前常見的電源供應器的缺點在於，無法藉由外部之開關來改變輸出電流、輸出電壓或輸出之佔空比，甚為可惜；或是達成此等目的之電路過於複雜而價格昂貴。A power supply is a common electronic device that provides back-end loads or power supplies for electrical appliances. A disadvantage of the current common power supply is that it is a pity that the output current, output voltage, or output duty cycle cannot be changed by an external switch; or the circuit for achieving such a purpose is too complicated and expensive.
例如台灣專利證書號I398758係揭露一種智慧型箝制電路，適用於設置在一電源供應器中，並切換地接收一交流電壓以控制一受箝制開關，包括：一開關切換器，受交流電壓控制而切換於導通狀態和截止狀態間；一傳壓單元，受開關切換器控制而根據一產生自交流電壓的待機電壓送出一耦合電壓；及一偵測器，基於耦合電壓和一供電良好信號來控制受箝制開關；當電源供應器從開機模式進入停機模式時，會切換為停止接收交流電壓，開關切換器便切換為截止並造成耦合電壓為低電位，且供電良好信號因進入停機模式而處於低電位，偵測器因此截止受箝制開關。然而台灣專利證書號I398758有著上述無法藉由外部之開關來改變輸出電流、輸出電壓或輸出之佔空比的缺點。For example, Taiwan Patent No. I398758 discloses a smart clamp circuit suitable for being disposed in a power supply and switchingly receiving an AC voltage to control a clamped switch, including: a switch switch controlled by an AC voltage. Switching between a conducting state and an off state; a voltage transmitting unit controlled by the switching switch to send a coupling voltage according to a standby voltage generated from the alternating voltage; and a detector for controlling based on the coupling voltage and a good power supply signal Clamped switch; when the power supply enters the stop mode from the power-on mode, it will switch to stop receiving AC voltage, the switch switch will switch to cut-off and cause the coupling voltage to be low, and the good power supply signal is low due to entering the stop mode. At the potential, the detector is thus cut off by the clamp switch. However, Taiwan Patent No. I398758 has the above disadvantages of being unable to change the duty ratio of the output current, output voltage or output by an external switch.
又例如台灣專利證書號I398763係揭露一種交換式電源轉換電路，用以接收輸入電壓之電能而產生輸出電壓至系統電路，包括：具有第一開關電路之電源電路，藉由第一開關電路導通或截止分別產生輸出電壓與第一輔助電壓；迴授電路，用以因應輸出電壓產生迴授信號；以及控制單元，連接於第一開關電路與迴授電路，用以因應迴授信號與系統電路之關閉狀態與運作狀態控制第一開關電路導通或截止；其中，於系統電路之電源狀態為關閉狀態時，控制單元控制第一開關電路停止運作或間歇性運作，使輸出電壓與第一輔助電壓之電壓值常態低於額定電壓值或為零電壓值。然而台灣專利證書號I398763有著上述無法藉由外部之開關來改變輸出電流、輸出電壓或輸出之佔空比的缺點。For example, Taiwan Patent No. I398763 discloses an exchange type power conversion circuit for receiving power of an input voltage to generate an output voltage to a system circuit, comprising: a power supply circuit having a first switching circuit, which is turned on by the first switching circuit or The output voltage and the first auxiliary voltage are respectively generated by the cutoff; the feedback circuit is configured to generate a feedback signal in response to the output voltage; and the control unit is connected to the first switching circuit and the feedback circuit for responding to the feedback signal and the system circuit The off state and the operating state control the first switch circuit to be turned on or off; wherein, when the power state of the system circuit is off, the control unit controls the first switch circuit to stop or intermittently operate, so that the output voltage and the first auxiliary voltage are The voltage value is normally lower than the rated voltage value or the zero voltage value. However, Taiwan Patent No. I398763 has the above disadvantages of being unable to change the duty ratio of the output current, the output voltage or the output by an external switch.
再例如台灣專利證書號I399007係揭露一種種具交直流電壓偵測之電源供應單元及其電源供應系統，該電源供應單元之電源控制單元可以依據第一電壓的電壓類型(例如交流電壓或直流電壓)與電壓值大小對應調整第一級電源電路與旁路開關電路的運作以提升效率，且應用於高壓直流電壓的電源供應系統時，可以在直流型式的第一電壓其電壓值不足時，防止因第一電壓其電壓值不足或過低導致電源供應單元無法輸出額定電壓值的輸出電壓之問題。然而台灣專利證書號I399007有著上述無法藉由外部之開關來改變輸出電流、輸出電壓或輸出之佔空比的缺點。For example, Taiwan Patent No. I399007 discloses a power supply unit with AC/DC voltage detection and a power supply system thereof. The power supply control unit of the power supply unit can be based on the voltage type of the first voltage (for example, an alternating voltage or a direct current voltage). Adjusting the operation of the first-stage power supply circuit and the bypass switch circuit according to the magnitude of the voltage value to improve the efficiency, and when applied to the power supply system of the high-voltage DC voltage, the first voltage of the DC type can be prevented when the voltage value thereof is insufficient. The problem that the power supply unit cannot output the output voltage of the rated voltage value due to the voltage value of the first voltage being insufficient or too low. However, Taiwan Patent No. I399007 has the above disadvantages of being unable to change the duty ratio of the output current, the output voltage or the output by an external switch.
綜上所述，目前常見的電源供應器的缺點在於，無法藉由外部之開關來改變輸出電流、輸出電壓或輸出之佔空比，甚為可惜；或是達成此等目的之電路過於複雜而價格昂貴。In summary, the current common power supply has the disadvantage that it is a pity that the output current, output voltage or output duty cycle cannot be changed by an external switch; or the circuit for achieving such a purpose is too complicated. expensive.

當該開關30斷路時，該電源轉換單元102的輸出電流或輸出電壓會改變（輸出電流會降為零；輸出電壓會降為零），該電源轉換單元102的內部線路之電流或電壓會改變，由該偵測控制線路110 偵知，當該開關30於一定時間內再度導通時，即可控制調整該電源轉換單元102的輸出電流、輸出電壓或輸出之佔空比。亦即該電源轉換單元102的輸出電流、輸出電壓或輸出之佔空比可由該開關30導通斷路之切換次數或該開關30斷路與導通之間之時間差決定。When the switch 30 is open, the output current or the output voltage of the power conversion unit 102 will change (the output current will drop to zero; the output voltage will drop to zero), and the current or voltage of the internal line of the power conversion unit 102 will change. The detection control circuit 110 detects that when the switch 30 is turned on again within a certain period of time, the duty ratio of the output current, the output voltage, or the output of the power conversion unit 102 can be controlled. That is, the duty ratio of the output current, the output voltage, or the output of the power conversion unit 102 can be determined by the number of times the switch 30 is turned on or off, or the time difference between the open and the conduction of the switch 30.
