Zusammenfassung:	To provide a power supply system that reduces the occurrence of unbalance between three phases, thereby contributing to the deterrence of instability in a power system, and to provide a three-phase to single-phase inverter for the system.SOLUTION: The power supply system is for supplying power from a commercial grid to individual customers. The power supply system includes at least three-phase three-wire wiring and a three-phase to single-phase inverter. The three-phase three-wire wiring draws power from a pole transformer arranged in the commercial grid to the interior of each consumer in a three-phase three-wire configuration. The three-phase to single-phase inverter converts the three-phase power drawn indoors by the three-phase three-wire wiring into single-phase power.SELECTED DRAWING: Figure 4 【課題】三相間でのアンバランスが発生する事態を低減して、電力系統の不安定の抑止に資する電力供給システム及び当該システムに用いる三相－単相インバータを提供することを目的とする。【解決手段】本発明は、商用系統から各需要家に電力を供給する電力供給システムであって、少なくとも三相３線式配線と、三相－単相インバータとを、備え、前記三相３線式配線は、商用系統に配置された柱上変圧器から三相３線式のままで各需要家の屋内に電力を引き込むものであり、前記三相－単相インバータは、前記三相３線式配線によって屋内に引き込まれた三相電力を単相電力に変換することを特徴とする電力供給システムとすることで課題を解決した。【選択図】図４
