Abstract: The invention relates to a grid synchronizer for connecting an AC output of a power converter to the AC grid mains. In one aspect the invention provides a grid synchronizer comprising an inverter controller to control an AC output of the inverter, the controller including a receiver to receive grid data from a grid sensor location remote from said inverter. In another aspect we describe techniques for rapid removal of charge from a control terminal of a power switching device such as a MOSFET, IGBT or Thyristor using a particular driver circuit.
