This paper describes a power-transfer principle and power-loss analysis of phase-shift-controlled switched-capacitor-based resonant converters (PSC-SCRC). Power loss in the PSC-SCRC is theoretically derived and compared with that in a conventional switched-capacitor converter (SCC) and a frequency-controlled SCRC (FC-SCRC). As a result, it is clarified that a PSC-SCRC has no theoretical power loss unlike an SCC and an FC-SCRC. The experimental results agree well with the theoretical ones.
