| 主权项 | 1. A grid tied inverter connectable to an electricity grid, the grid tied inverter comprising: 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 synchronised to the electricity grid, and including a transformer; and a circuit having a first side connected to the DC to DC current fed converter and a second side having an output line connected to the grid, wherein the DC to DC current fed converter comprises a buck-boost stage connected to the DC voltage source, wherein the buck-boost stage is active only during generation of a lower portion of a voltage waveform at the output line. | ||
