Patent ID: 10547245

Abstract:
In a power converter including a plurality of switches, a plurality of freewheeling diodes each electrically connected in anti-parallel with a respective one of the switches, a freewheeling current input electrically connected to an output terminal of each of the switches, and a freewheeling current output electrically connected to an input terminal of each of the switches, a plurality of freewheeling current paths are defined, each of which is an electrical path passing through a respective one of the freewheeling diodes from the freewheeling current input to the freewheeling current output. At least one of the freewheeling current paths is a maximum path having a maximum impedance among the freewheeling current paths. A voltage drop across the freewheeling diode included in the maximum path is less than a voltage drop across each of the other freewheeling diodes when a freewheeling current flows through each of the plurality of freewheeling diodes.
