Single Stage Push-Pull Forward Inverter of PV Power Source
This paper proposed a single stage inverter for PhotoVoltaic(PV). The inverter is a push-pull forward converter employed synchronous rectifier technique. The push-pull forward converter is used to convert the photovoltaic battery output voltage into high frequency SPWM square wave, and the rectifier circuit is used to change the polarity of the isolation high frequency transformer output SPWM wave. For improve performance of the inverter in both the command tracking and the load disturbance regulation, a PID control strategy is realized by using the TMS320LF28335 DSP. Theoretical analysis and experimental results indicate that the proposed topology and control scheme are promising for the applications of PV power supply.
