Abstract

This invention relates to integrated circuits for power conditioning units, that is circuits to supply power to a mains supply, such as domestic grid mains from, for example, a fuel cell or photovoltaic device, and also to circuits for supplying power to a mains supply, such as domestic grid mains, from a dc supply from a low voltage power source such as a photovoltaic device or fuel cell. We describe a semiconductor-on-insulator integrated circuit die comprising a substrate bearing a power conditioning circuit, the power conditioning circuit comprising at least two power devices, one of said power devices being a lateral power device, another of said power devices being a vertical power device. We further describe a power conditioning circuit for providing power from a DC supply to an alternating current mains power supply line, the circuit comprising: a DC input to receive DC power from said DC supply; an AC output for connection to said AC mains power supply line; a DC-to-DC converter having an input coupled to said DC input and having an output; a DC-to-AC converter having a DC input and an AC output to convert DC power to AC power for output onto said power supply line; and a DC voltage regulator coupled between the output of said DC-to-DC converter and the input of said DC-to-AC converter to regulate said DC voltage input to said DC-to-AC converter; and wherein said regulator is configured to control an AC output current of said circuit by controlling said DC voltage input to said DC-to-AC converter.
