直交磁心を主構成要素とするローカルエネルギー利用システム用DC-AC変換装置

抄録

A new DC-AC converter for local energy utilization system is proposed in this paper. The DC-AC converter is constructed with orthogonal cores and a three-phase thyristor inverter. Using the DC-AC converter, we can easily supply the power from a DC power source to an AC distribution line. The DC-AC converter exhibits following features:
(1) The isolation between the DC power source and the AC distribution line is good. (2) The power can be transferred from the DC power source to the AC distribution line over the wide DC voltage range of the input. (3) The DC-AC converter has simple construction and the maintenance is easy.
The DC-AC converter presented here is useful for utilizing small powers such as the power generated by solar cells.
