Resonant Converter Design Using Two-Port Passive Network: Single Frequency Design

This paper proposes a design method of resonant converter through two-port network analysis. The impedance conversion characteristics of a two-port network consisting solely of passive elements are analyzed at a single frequency. Through this analysis, this paper presents a general method of designing resonant networks that satisfy the desired input- and output-specifications under the rated conditions and has the desired characteristics for load variations. This design method allows designers to configure resonant networks suitable for specific applications without relying on case studies. To verify the proposed design concept, design examples are introduced and simulation results are provided.
