Abstract
In this paper, it is considered spike voltage that is generated by ignoring the recovery time of switching device, turn on and turn off time. In the same principle, this spike voltage will be applicable to diode recovery time. The spike voltage causes to break down insulation of input transformer. So, we will show how to remove spike voltage by optimizing value of R and C and using switching diode which have fast recovery time.
