Abstract :
Resonant power supply involves the use of zero-current-switching (ZCS) high-frequency inverters. The load can be considered as a bandpass, so that a variation of its resonant frequency (by decreasing of distance of the power consumer) means that the inverter switches at higher current which can damage the IGBTs. This paper proposes a closed-loop-control of the inverter frequency to preserve the ZCS condition
