Abstract
A power converter according to one embodiment includes a controller that switches between a boosting operation in a boost circuit and a pulse-width modulation operation in a single-phase inverter. The controller modifies an output from a voltage detection filter based on a delay compensating value for compensating a detection delay introduced by the voltage detection filter, when switching is performed the boosting operation in the boost circuit to the PWM operation in the single-phase inverter.
