Push-pull topology is a derivative of two forward converters operating 180 degrees out of phase.
This configuration allows operation in the first and third quadrant of the hysteresis loop, with a better
utilization of the magnetic core of the transformer. The maximum voltage stress of the switching
MOSFETs is twice the input voltage which is the same as the the forward topology. A current mode PWM
converter avoids run away of the flux core by monitoring the current of each of the push-pull transistors
and forcing alternate current pulses to have equal amplitude.， 大小：134 KB
