Abstract :
The paper presents a Photovoltaic (PV) Inverter System based on TMS320F28027 that can not only achieve single phase DC/AC converting by a full-bridge inverter, but also realize the function of same phase-frequency between sine waveform generated from PV Inverter System and the reference waveform from grid. Furthermore, the single phase DC/VC converting is controlled by means of SPWM generated by taking advantage of the peripheral of TMS320F28027. In addition, PV grid-connected is made up of frequency tracking and phase difference detecting, which needs TMS320F28027 to capture the frequency and calculate the phase by pulse edge detecting according to feedback circuits that can transform sine waveform into pulse waveform. Consequently, PV Inverter System can make single phase DC/VC converting and PV grid-connected come true successfully.
