Abstract

본 발명은 인버터 장치는 상마다에 병렬로 접속된 복수의 스위칭 회로에 있어서 안정된 전류 균형을 도모한다.The present invention achieves a stable current balance in a plurality of switching circuits connected in parallel to each phase.

본 발명의 인버터 장치는 인버터 회로의 U상을 구성하는 스위칭 회로(TrU1과, TrX1, TrX2및 TrU3과 TrX3)을 각각 직렬로 접속하고, 또 이들 접속선과 U상의 출력선 사이에 인덕터부(L1내지 L3)을 삽입한다. 전류시에는 스위칭 회로(TrU1)의 트랜지스터를 흐르고 있는 전류는 임피던스의 차에 의해 스위칭 회로(TrX1)로 전류한다. 이와 마찬가지로, 스위칭 회로(TrU2)를 흐르고 있는 전류는 스위칭 회로(TrX2)로 전류하고, 스위칭 회로(TrX3)을 흐르고 있는 전류는 스위칭 회로(TrX3)으로 각각 전류한다. 이 결과, 전류시에 있어서 양호한 전류 균형이 확보된다.The inverter device of the present invention connects the switching circuits (TrU 1 , TrX 1 , TrX 2 , TrU 3, and TrX 3 ) constituting the U phase of the inverter circuit in series, and between these connection lines and the output line of the U phase. The inductor parts L 1 to L 3 are inserted. Current when a current flowing through a transistor in the switching circuit (TrU 1) are current to the switching circuit (TrX 1) by the difference of the impedance. Likewise, the current that flows through the switching circuit (TrU 2) and the current to the switching circuit (TrX 2), the current flowing to the switching circuit (TrX 3) are each a current switching circuit (TrX 3). As a result, a good current balance is ensured at the time of current.
