Abstract

See full text

An inverter device includes a DC positive input line and a DC negative input line, a main bridge which includes a pair of series-connected switching elements with diodes being connected in reverse parallel with the switching elements respectively, an auxiliary bridge which includes a pair of series-connected switching elements with diodes being connected in reverse parallel with the switching elements respectively and a current-limiting reactor. A plurality of sets each one of which includes the main bridge and the auxiliary bridge is connected between the DC positive and negative input lines. Each set constitutes a phase. The current-limiting reactor is connected between a common connection point of both switching elements of the main bridge and a common connection point of both switching elements of the auxiliary bridge in each set.
