Abstract
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.
