INTERCONNECTION INVERTER

WIPO Patent Application WO/2010/055713

A1

An interconnection inverter comprises an inverter (1) that pulse-width modulates an output from a DC power supply (5); a first pair of capacitors (41) that is disposed on an input side of the inverter and that consists of two capacitors so series-connected as to form a neutral point; a second pair of capacitors (42) that is disposed on an output side of the inverter and that consists of two capacitors so series-connected as to form a neutral point; a leakage-current bypassing path (g) that is formed by connecting the neutral point of the first pair of capacitors to that of the second pair of capacitors; at least one common-mode choke coil (3) that is disposed between the first pair of capacitors and the second pair of capacitors and that suppresses a common-mode current generated in the inverter; and an output filter (2) that converts the pulse-width modulated voltage output by the inverter to a voltage having a sinusoidal waveform.
