摘要： A switched mode power supply (SMPS) is disclosed. The SMPS includes a mechanism for discharging charge stored in an input capacitor, upon the SMPS becoming disconnection from the mains, for instance by being unplugged. The SMPS includes a detector for detecting the disconnection of the mains, and a discharge circuit. The discharge circuit comprises a discharge element. The discharge element may be a part of the SMPS which is used otherwise, for instance, a high- voltage current source, or a bus capacitor or it may be an additional element, for instance a resistance load. The discharge circuit is adapted for, in response to the detector detecting a disconnection of the mains, discharging the input capacitor along a path. The detector controls a switch which engages the discharge circuit upon the detection. The switch forms a part of the discharge path.
Also disclosed are methods of operating an SMPS including a safety arrangement, and a controller adapted or configured to operate such methods.

摘要： For many applications an SMPS is designed to operate in boundary conduction mode. As the load decreases the switching frequency increases, and so the concept of valley skipping may be used in which the switching frequency is clamped, by delaying to turn on the time of the active switch, for an integral number of cycles of a resonant circuit in the SMPS. With further reduction of the load, additional valleys may be skipped. However, each change in the number of valleys skipped results in a step in the input current that is drawn, distorting the ideal mains sine wave, thereby increasing unwanted harmonics.
A control method is disclosed, which reduces the steps: instead of a constant on-time for the switch, the duration of the on-time is increased each time an additional valley to be skipped. The predetermined increase may be either a fixed fractional increase or a further additional increment; it may be determined by a small regulation loop that multiplies the on-time from the main loop with a factor equal to the ratio between measured period time and the sum of primary and secondary stroke times.
摘要翻译：对于许多应用，SMPS被设计为在边界传导模式下工作。随着负载减小，开关频率增加，因此可以使用谷跳跃的概念，其中开关频率被钳位，通过延迟有源开关的时间来导通谐振电路的整数个周期 SMPS。随着负载的进一步减少，可能会跳过额外的谷。然而，跳过的谷数的每个变化导致所绘制的输入电流的步长，使理想的主电源正弦波失真，从而增加不期望的谐波。公开了一种控制方法，其减少了以下步骤：代替开关的恒定导通时间，每次要跳过的额外谷值时，导通时间的持续时间增加。预定增加可以是固定的分数增加或另外的附加增量; 可以通过将来自主回路的导通时间乘以等于测量的周期时间与初级和次级行程时间之和的因子的小的调节回路来确定。
