Abstract
Analytical results, design considerations, and experimental results at 1.5 MHz are presented, for a novel resonant high-frequency dc/dc converter. The circuit works virtually without dynamic losses at several-MHz switching frequency. The analysis gives the permissible area of the equivalent load impedance for lossless operation, presents a model for regulation by narrow-band frequency control, and characterizes the output full-wave rectifier. Experimental data from a 1.5-MHz 40-W converter verify the results of the theoretical analysis. The measured efficiency was 85 percent.
