Abstract

The present disclosure provides an interleaved parallel circuit, an integrated power module and an integrated power chip. The interleaved parallel circuit includes a first bridge arm and a second bridge arm at least partly formed in a wafer containing a plurality of first cell groups and a plurality of second cell groups. The plurality of first cell groups are configured to form the first upper bridge-arm switch and the plurality of second cell groups are configured to form the second upper bridge-arm switch, or the plurality of first cell groups are configured to form the first lower bridge-arm switch and the plurality of second cell groups are configured to form the second lower bridge-arm switch. The plurality of first cell groups and the plurality of second cell groups are switched on and off in an interleaved mode.
