9. A power conditioning unit for delivering power from a dc power source to a mains utility supply the power conditioning unit comprising:
-
input connection means for connecting to the dc power source; output connection means for connecting to the mains utility supply; voltage increasing means for increasing the voltage supplied to the input connection means; voltage reducing means for reducing the voltage supplied by the voltage increasing means; dc to ac conversion means for converting a direct current supplied by the voltage reducing means to an alternating current suitable for supplying to the mains utility supply; voltage sensing means for sensing a voltage on the output connection means; reference current generation means for generating a reference current responsive to said sensing; current sensing means for sensing a supply current in the dc to ac conversion means; and control means for controlling the voltage reducing means responsive to a difference between the reference current and the supply current.
