Abstract: A power converter to supply power to each phase of a three-phase motor includes a booster circuit connected to a DC power supply to boost an input voltage input from the DC power supply in response to a pulse width modulation boosting signal, an inverter connected to the booster circuit and including a three-phase switching circuit including switches, and an output connected to the three-phase switching circuit to supply power to each phase of the three-phase motor, and a controller to output the pulse width modulation boosting signal to the booster circuit and output the pulse width modulation boosting signal to the booster circuit when detecting that the booster circuit is in a boosted state.
