ABSTRACT

• MOSFET-based inverter topologies suffer from one
  or more of these drawbacks MOSFET failure risk
  from body diode reverse recovery, increased
  conduction losses due to more devices, or low
  magnetics utilization.
• By splitting the conventional MOSFET based phase
  leg with an optimized inductor, this paper
  proposes a novel MOSFET-based phase leg
  configuration to minimize these drawbacks.
• Based on the proposed phase leg configuration, a
  high efficiency single-phase MOSFET
  transformerless inverter is presented for the PV
  microinverter applications.
• The pulsewidth modulation (PWM) modulation and
  circuit operation principle are then described.
• The common-mode and differential-mode voltage
  model is then presented and analyzed for circuit
  design.
