Abstract

This brief presents load-independent Class E2 parallel resonant dc-dc converter, which consists of load-independent Class E parallel resonant inverter and load-independent synchronous Class E voltage-driven low <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$dv/dt$ </tex-math></inline-formula> resonant rectifier. The proposed converter achieves zero-voltage-switching (ZVS) and zero-voltage-derivative-switching (ZVDS) at a rated load resistance, and maintains ZVS and a constant dc output voltage over a wide range of load resistance without additional elements or feedback control. The validity of the operation was confirmed by circuit simulation using LTspice and circuit experiments.
