Abstract
An output from an electric generator 1 is rectified by a DC converter unit 2. An output from the DC converter unit 2 is regulated in voltage by the DC-DC converter unit 3 and converted into an AC output having a predetermined frequency by the DC-AC converter unit 4. The DC-AC converter unit 4 includes a median converter unit 4-1 to form a median of the DC voltage output from the DC-DC converter unit 3, an inverter 4-2, and a filter 4-3 and outputs a single-phase three-wire output to output lines 5-1 to 5-5.
Claims4
A power supply apparatus comprising an inverter which converts a DC power supply output into an AC power having a predetermined frequency to output the AC power,
- wherein a DC-DC converter which switches the DC power supply output, regulates the DC power supply output to a predetermined voltage, and supplies the output to the inverter is arranged, and
- a median converting means to form a median of the DC voltage output from the DC-DC converter is arranged on the output side of the DC-DC converter.
