Hi,
As the title says, I´m deciding on the power stage for a 5kW DC/DC application at 48Vin. I´ve always heard that a H full bridge should be used for applications above 1kW, however the push pull has the advantage of using only 2 switching elements which could potentially reduce the overall conduction & switching losses. I know it has some drawbacks like more voltage stress on the MOSFETs as well as more inefficient utilization of the transformer, since only one winding is conducting every time.
Does it make sense to consider push pull for this application or should I scrap the idea and go straight for an H bridge ?
