Abstract
A series connection circuit of IGBTs and an AC switch are contained in one package. The series connection circuit is connected between the positive and negative terminals of a DC power source, and the AC switch is connected between a neutral point of the DC power source and a series connection point between the IGBTs. Straight conductor strips can be used to connect terminals on the package to the DC power source, thereby reducing inductance and thus also reducing voltage spikes.
