A controlled rectifier resonant bridge inverter having its operating frequency varied to maintain a regulated voltage supplied to a load. The inverter has a commutating circuit having a first resonant frequency defining a maximum inverter operating frequency during normal load conditions and a second higher resonant frequency defining a higher maximum inverter operating frequency during short circuit load conditions to provide reliable inverter operation for all load conditions including a short circuit load condition.
