Abstract

A resonant power converter includes a DC power source, a positive DC conductor, a negative DC conductor, a phase conductor, and a power converting unit between the DC power source and phase conductor. The power converting unit includes a first switch between the positive DC conductor and phase conductor, a first diode in parallel with the first switch, a second switch between the negative DC conductor and phase conductor, and a second diode in parallel with the second switch. The resonant power converter includes a resonant auxiliary switching circuit between the DC power source and phase conductor. The resonant auxiliary switching circuit includes an inductor in series with a control means, and auxiliary diodes in series with the control means. The inductor is a current discriminating inductor adapted to become saturated by currents flowing through the inductor during normal operation such that the inductance of the inductor is reduced.
