Abstract

PURPOSE:To improve the utilization rate of an inverter as a power source for feeding both three-phase and single-phase loads, by providing a three-phase/two-phase converting transformer in parallel to the three-phase load of a three-phase three- wire system sine-wave inverter, and connecting a halved single-phase load to the secondary side of said transformer. CONSTITUTION:A three-phase three-wire output system multiple inverter IN is connected to a three-phase load 3 and moreover with a Scott connection system transformer 11 for a three-phase/two-phase conversion. Halved single-phase loads 1A and 1B are provided on the output side of said transformer 11. Therefore, dividing the single-phase load into two alone will be sufficient enough, so that the division is facilitated, and the current unbalance of the converting transformer observed from the inverter is reduced. Accordingly, it is possible to improve the utilization of the inverter.
