Realization of the maximum utilization effectiveness of semiconductor devices and magnetic components for push-pull converters

The energy transfer with isolation is used to transfer the energy which can not be used directly to the energy which can be utilized directly. This is achieved via switching control, i.e. duty-cycle control. However, by this way, the low-duty cycle tends to deteriorate the utilization effectiveness of semiconductor devices and magnetic components. Consequently, to overcome this problem, a new control topology is proposed herein, together with some simulation and experimental results are provided to demonstrate its feasibility.
