PSO-based Design Procedure for Class-DE Inverter

Abstract

In this research, a novel numerical design strategy is presented for the class-DE inverter design, which is based on particle swarm optimization (PSO) algorithm. Compared with previous numerical design methods based on Newton’s method, the proposed method shows convenience without restricting the number of design parameters. Additionally, no initial estimation is needed for ensuring convergence. Therefore, system-level optimization, which considers optimized inductor designs, can be realized. A design example of the class-DE inverter is shown in this paper. The numerical calculation proved the validity of the proposed design method.
