Claim Text:
1. An electricity handling device comprising: an AC tied inverter; an electrical interface configured to connect to each of a load device powered by an AC source, the AC source, and an energy source; a switching system configured to connect the AC tied inverter to the AC source, and the AC source to the load device; and a grid monitor configured to detect when the AC source is failing and to control the switching system to disconnect the AC tied inverter from the AC source and disconnect the load device from the AC source, wherein when the AC tied inverter and the load device are disconnected from the AC source, the AC tied inverter provides power to the load device from the energy source, wherein the AC tied inverter comprises a DC to DC current fed push-pull converter configured to generate a rectified current waveform from a DC voltage source, the rectified current waveform being substantially synchronized to the AC source, and wherein the DC to DC current fed converter comprises a buck-boost stage connectable to the DC voltage source, wherein the buck-boost stage is active only during generation of a lower portion of a voltage waveform at an output line.
