R60xxVNx series Reduction in Switching Loss of Phase-Shift Full-Bridge Converter using PrestoMOS™ Application Note
●PSFB converter feature many advantages including the following.
■For the primary side full bridge circuit, the switching loss is reduced with the zero-voltage switching (ZVS) operation.
■The primary side input can be isolated from the secondary side output.
■A relatively high power (a few kW and more) can be handled.
●However, the circuit design is more difficult compared with general hard switching DC-DC converters, and the expected performance may not be realized if the circuits are not designed properly in accordance with the switching characteristics of the MOSFET to be used.
●This application note describes the basic operation about PSFB converter first. After that it explains the switching characteristics of the primary side MOSFET, and points for optimizing the circuit design. We expect that understanding these will help you to fully deliver the performance of Presto MOSTM R60xxVNx series, which are ROHM’s super junction MOSFET (SJ-MOSFET) for PSFB converter
