Abstract
A power module including: a power conversion unit including N switching-element pairs; and a control circuit. The control circuit receives N command signals, which correspond respectively to the N switching-element pairs, and a shared enable signal. The control circuit is configured to, when the enable signal is negated, execute all-off control of turning off all of the switching elements constituting the power conversion unit, and when the enable signal is asserted, execute normal control, dead-time addition control, and dead-time compensation control for each of the switching-element pairs per period of a corresponding command signal.
