Many articles and papers have been published recently promoting the performance and benefits of the Phase-Shift,Full-Bridge Topology and rightly so. This topology productively utilizes the same elements that have been plaguing
power supply designers for decades, those infamous parasitic components. The topology enables designers to advantageously employ transformer leakage inductance, MOSFET output capacitance and the MOSFET body diode, enabling
designers to easily move their designs upwards in frequency.The topology offers additional advantages like zerovoltage-switching at a constant switching frequency, which substantially reduces switching losses. This can be significant enough to eliminate heatsinking of power MOSFETS and/or enabling the use of less expensive power devices.
