An AC tied inverter connectable to an AC source, the AC tied inverter including a DC to DC current fed push-pull converter operable to generate a current waveform from a DC voltage source, the current waveform being substantially synchronized to the AC source, the push-pull converter including a transformer including a first side connectable to a battery and a second side connectable to the AC source, wherein each of the two primary sides is connected to ground via a switching transistor; and respective voltage clamps are connected between the respective primary side of the transformer and the respective switching transistor, the voltage clamp commutating the current from the respective primary side of the transformer when the switching transistor is turned off.

AC tied inverter, system and method

A grid tied inverter connectable to an electricity grid having a DC to DC current fed push-pull inverter to generate a current waveform from a DC voltage source. The push-pull inverter includes a transformer having a first side winding connectable to a battery and a second side winding connectable to the grid. The first end of the second side winding is connected between two diodes connected in series between a positive and negative output rail and being oriented in the same direction. The second end of the second side winding is connected between two capacitors connected in series between the positive and negative output rail. A further winding is connected at one end between the two capacitors and at its other end between another two diodes connected in series between the positive and negative output rail.
