title: Performance, design and control of a series-parallel (CL/sup 2/-type) resonant DC/DC converter
abstract: The three-element resonant network has various topological alternatives, one of which, a prospective compound topology, is investigated in detail. The converter uses one capacitor (C) and two inductors (L/sup 2/), to form a compound type CL/sup 2/ network. Various advantages and limitations of the converter are detailed, and a new design procedure for such converters is also introduced. The converter may be controlled by varying the switching frequency or by pulse-width modulation. An experimental prototype has been produced and an excellent performance in the lagging power-factor mode has been confirmed
