Abstract
No-load losses normally associated with transformer-isolated inverter circuits employing high frequency switching devices are substantially eliminated by electrically short-circuiting the load terminals of the inverter to quickly and efficiently shut down inverter operation and thereby reduce the no-load losses to at least the fall-back current losses of the inverter.
