摘要： A controller which has functions of remote control, multiple protection and PWM inside. The controller can shut down and latch the converter, when a failure happens (such as under voltage and over voltage of output, and over power protection). But, under-voltage and over-power protection will also happen when Vin is decreased by AC interruption or Vin source is removed. This invention is to provide a method to reset the latch protection by detecting Vin and Vo voltage.

摘要： A flyback power converter includes a power switch connected to a primary side of a transformer, and a sensing signal is provided for a control circuit to switch the power switch so as for the transformer to convert an input voltage into an output voltage. The sensing signal is a function of the input voltage, and the control circuit extracts a variation of the sensing signal during a preset time period. The variation of the sensing signal is used to prevent the output ripple and the green mode entry point of the flyback power converter from varying with the input voltage.
