摘要： In a preferred embodiment, there is provided a switched mode power supply operable in start-up mode, normal mode and standby mode. The power supply may comprise a transformer having a primary winding on a primary side and a secondary winding on a secondary side, the primary winding being coupleable to a DC input voltage, and circuitry on the secondary side being arranged to provide a DC output voltage; and a power controller. The power controller may comprise a regulation controller for regulating a DC supply voltage on a supply line during standby mode, and a high voltage device coupled to the DC input voltage and the supply line. The current through the high voltage device to the supply line, during standby mode, may be controlled by the regulation controller. During standby mode, when the supply voltage is greater than or equal to a reference voltage, the current through the high voltage device to the supply line is substantially zero. When the supply voltage is less than the reference voltage, the greater the difference between the supply voltage and the reference voltage, the greater the current through the high voltage device to the supply line. In other preferred embodiments, there is also provided the power controller itself and a method for regulating a supply voltage during standby mode.
摘要翻译：在优选实施例中，提供了一种在启动模式，正常模式和待机模式下可操作的开关模式电源。电源可以包括具有初级侧的初级绕组和次级侧的次级绕组的变压器，初级绕组可耦合到DC输入电压，并且次级侧上的电路布置成提供DC输出电压; 和电源控制器。功率控制器可以包括用于在待机模式期间调节供电线路上的直流电源电压的调节控制器和耦合到直流输入电压和电源线的高压设备。电流通过高压设备到电源线，在待机模式下，可由调节控制器控制。在待机模式下，当电源电压大于或等于参考电压时，通过高压设备到电源线的电流基本为零。当电源电压小于参考电压时，电源电压和参考电压之差越大，通过高压设备到电源线的电流越大。在其他优选实施例中，还提供了功率控制器本身以及用于在待机模式期间调节电源电压的方法。
