1 Introduction. This application note presents a bidirectional 3-phase DC-AC solution used in solar application systems, based on the TMS320F28035 MCU (see Figure 1). If the load must take energy from the AC grid, the solution could work in rectifier mode so that the system can transfer 3-phase AC power from the grid to the DC voltage.
The study concludes that the maximum power point tracking (MPPT) efficiency of the bidirectional energy storage photovoltaic grid-connected inverter designed was as high as 99.9%. The distortion rate of the grid-connected current waveform was within 2% and the DC current component was less than 0.5%.
