1. A power conditioning unit for delivering power from a dc power source to an ac mains utility supply, the power conditioning unit comprising:
a plurality of input terminals for connecting to the dc power source; a plurality of output terminals for connecting to the ac mains utility supply; a voltage increasing converter connected to the plurality of input terminals; a voltage reducing converter connected to the voltage increasing converter; a dc-to-ac converter connected to the voltage reducing converter and to the plurality of output terminals; a voltage sensor for sensing a voltage on the plurality of output terminals; a reference current generator for generating a reference current responsive to said sensing; a current sensor for sensing a supply current in the dc to ac converter; and a comparator for controlling the voltage reducing means responsive to a difference between the reference current and the supply current.
