SMPS: Phase-Shifted Full-Bridge Converters

Phase-shifted full-bridge (PSFB) converters are used to step down high DC voltages and to provide isolation in medium to high power applications (> 1000 W). PSFB converters are similar to conventional full-bridge DC-DC converters, but with a phase shifting control. The phase shift full-bridge converter can achieve soft switching by phase-shifting the gate signals...

SMPS: Symmetrical Isolated Converters

The previous article in our series on switched-mode power supplies (SMPS) covered asymmetrical isolated converter topologies. Now we will investigate several symmetrical isolated converters along with their advantages and disadvantages for different applications. Symmetrical converters require an even number of switches. The full available flux swing in both quadrants of the B-H loop is used, thus...
