1. An interleaved parallel circuit comprising a first bridge arm and a second bridge arm, whereinthe first bridge arm comprises:

  • a first upper bridge-arm switch comprising a first terminal, a second terminal and a control terminal; and

    a first lower bridge-arm switch comprising a first terminal, a second terminal and a control terminal;

    wherein the second terminal of the first upper bridge-arm switch is electrically connected to the first terminal of the first lower bridge-arm switch;

    the second bridge arm comprises;

    a second upper bridge-arm switch comprising a first terminal, a second terminal and a control terminal; and

    a second lower bridge-arm switch comprising a first terminal, a second terminal and a control terminal;

    wherein the first bridge arm is connected in parallel with the second bridge arm;

    the second terminal of the second upper bridge-arm switch is electrically connected to the first terminal of the second lower bridge-arm switch;

    wherein the first bridge arm and the second bridge arm are at least partly formed in a wafer containing a plurality of first cell groups and a plurality of second cell groups;

    wherein the plurality of first cell groups are configured to form the first upper bridge-arm switch of the first bridge arm and the plurality of second cell groups are configured to form the second upper bridge-arm switch of the second bridge arm; and

    the plurality of first cell groups and the plurality of second cell groups are switched on and off alternatingly;

    wherein the plurality of first cell groups are disposed in a first region of the wafer, and the plurality of second cell groups are disposed in a second region of the wafer;

    wherein the first region contains a plurality of first sub-regions, and the second region contains a plurality of second sub-regions, each of the first sub-regions and the second sub-regions is in a stripe shape or a polygon shape, and the first sub-regions and the second sub-regions are arranged alternatively.
