Abstract
A power module is a power module having a PFC (power factor correction) function. The power module includes: IGBTs in a pair; first diodes in a pair connected to the IGBTs in a pair, the first diodes forming a reverse-conducting element; and second diodes in a pair connected to the IGBTs in a pair, the second diodes having a rectifying function. The power module further includes a driving IC that drives the IGBTs in a pair, and P terminals in a pair provided independently of each other. The P terminals are connected to one ends of the first diodes in a pair, respectively, the one ends being opposite to the other ends of the first diodes to which the IGBTs in a pair are connected.
