Abstract

An electric circuit comprising a transformer having first and second magnetically coupled inductors, a first switch which is connected to the first inductor, a second switch which is connected to the second inductor so as to be turned on and off by the second inductor; and a timing circuit for connection to the first switch for turning the first switch on and off. The second inductor is magnetically coupled to the first inductor such that flux reversal in the first inductor which occurs as the first switch is turned off will induce flux reversal in the second inductor which will thereby turn on the second switch. The circuit includes a damping element arranged to damp the operation of the second switch.
