Diode Reverse Recovery and its Effect on Switching …

WebDiode design/ selection The optimum choice for a given applica-tion depends on the power losses generated by the diode. The power losses come from two different phases. One is reverse switch-ing loss. The other one is forward conduction loss. Here, the switching loss is proportional to the maximum reverse recovery current, IRM of diode. Webcurrent is zero when the switch is open and the power loss is zero, thus V IN is being chopped. When the switch is closed, the voltage across it is zero and the power loss is ...
