Abstract
A phase shifted H-bridge resonant converter with symmetrical currents includes, a DC storage cap (), four switches (-) with a parallel turn off network consisting of diodes (-), capacitors (), (), (), (), resistors (), (), (), (). The subsequent output of switches (-), is arranged in series with DC blocking caps (-), connected to a low mutually coupled inductor (), an AC resistive load, capacitor (), resistor () across inductor (), with capacitors (), () that comprise a resonant tank circuit, and is connected to the primary of transformer (21) wherein the interaction between the two coils of the low mutually coupled inductor () provides symmetrical currents within the switches and resonant tank circuit. Further, output rectification may be arranged by use of secondary winding of transformer (), diodes (-), filter inductor (), filter capacitor (), and load resistor ().
