Abstract

In cascaded multi-converter power electronic systems, fast-acting control can make a power converter appear as a constant-power load (CPL) to a preceding converter. In this scenario, the characteristics of the feeding converter may differ appreciably compared to its conventional constant resistance load (CRL) operation. In this paper, the steady-state analysis of a series resonant converter (SRC) feeding a CPL is presented. Converter voltage gain and inductor rms current are derived in normalized form. The properties of an SRC feeding a CPL are compared with that of the traditional resistive loading. Implications of a CPL on the closed-loop control of an SRC are discussed. The proposed analytical approach is validated using circuit simulation and also on a 110 W laboratory prototype. © 2022 IEEE.
