A multiple stage switching type converter circuit provided between an AC source and a DC source is provided. The circuit includes a boost converter stage coupled to the AC source, a DC link capacitor stage comprising a DC link capacitor decoupled from an AC source and a DC source, and an isolated DC-DC converter stage coupled to the DC source. The multiple stage switching type converter circuit comprises a plurality of switches, each switch configured to operate at a baseline duty cycle, a baseline voltage, a baseline resistance, with a baseline current and providing a baseline switching time. At least one switch is altered to perform at a duty cycle differing from the baseline duty cycle, a voltage differing from the baseline voltage, a resistance differing from baseline resistance, with a current differing from the baseline current or using a switching time differing from the baseline switching time.
