  • AC tied inverter, system and method
    Patent number: 9350265
    Abstract: 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.
    Type: Grant
