Analysis and Design of a DC-DC Resonant Converter with a Class D Inverter and LCC Resonant Tank

The purpose of this paper is to provide an easy math analysis and design of a voltage class D inverter with a variant of the LCC resonant tank called capacitive impedance inverter (CII) and a full bridge rectifier. The analysis is performed using phasorial analysis reducing the complexity of the analysis, these equations are valid only in steady state and neglecting parasitic elements. In order to demonstrate theoretical results, experimental measures are also presented for this type of converter since, a zero current switching is applied to the switches of the inverter for minimizing switching losses and stress in the power electronic circuit, therefore, the efficiency of the converter results in a very high range. Experimental results are compared with the calculated ones.
