  • Power conversion device
    Patent number: 11398776
    Abstract: A power conversion device is provided. The power conversion device includes N power conversion circuits and M magnetic components, where N and M are positive integers greater than 1. Each of the N power conversion circuits includes M inductors. DC currents flowing through the M inductors respectively are unequal. Each one of the M inductors in different ones of the N power conversion circuits corresponds to each other to form a group of N corresponding inductors. In the N power conversion circuits, DC currents respectively flowing through the corresponding inductors are equal. Each of the M magnetic components includes a middle pillar, N side pillars and two substrates. The middle pillar has an air gap. In the N power conversion circuits, windings of N corresponding inductors are respectively wound around the N side pillars of one of the M magnetic components.
