Dual-loop constant voltage regulation in wireless power transfer systems using phase-shift and duty cycle modulation

Abstract

This study investigates the single transmitter and single receiver (STSR) with dual-output capability. This methodology utilizes dual half-wave rectification. Initially, the system topology of the STSR multi-channel voltage output is presented with the inductor-capacitor-capacitor-series (LCC-S) compensation topology, followed by an in-depth analysis of its double-channel voltage output characteristics. Through detailed analysis and empirical validation, the system is shown to maintain high efficiency and stable performance, making it well-suited for applications demanding reliable dual-voltage outputs under dynamic conditions.
