The family of DC-to-DC converters using the LC-PWM-RDC cell without resonant cycle interruption: analysis simulation and experimental results

A family of lossless commutation pulse-width-modulated DC-to-DC converters using a resonant disconnecting circuit (LC-PWM-RDC) cell without resonant cycle interruption. The most important property of this family of converters is the ability to regulate output power and voltage by PWM, with constant operating frequency, without load limitation, and without sacrificing the lossless commutation. As a consequence, the time response is improved, and the design procedure and implementation are facilitated. The authors present the complete operation principle and design-oriented analysis, output characteristics for numerical simulation examples, relevant equations, and simulation and experimental results
