Abstract:

One of the requirements for battery fuel cell and photovoltaic single phase applications is ripple free and steady dc power during normal operation Due to the difference in the instantaneous power at the dc and ac ports of such a single phase power processing application a power decoupling strategy is necessary Conventionally active or passive buffer circuits are used to address this issue in dc ac converters Under ideal conditions the dc input current has a double line frequency 100 Hz or 120 Hz ripple Thus a buffer circuit needs to compensate and inject a suitable voltage or current to cancel this input ripple In this regard one of the limitations in the complete elimination of double line frequency ripples on the dc input current is the increased capacitor voltage ripple and increased voltage stress over the circuit components A flexible active power decoupling FAPD approach is introduced in this paper to increase the power range of the system over a five level single stage dc ac converter Unlike conventional APD methods the proposed FAPD approach can effectively handle intermittent overloads without increasing the voltage stress on the power components The impact of the proposed control method has been investigated and the performance of the system has been verified in simulation
