Photovoltaic Inverter Power Supply Design
In this project, I designed a device to simulate function of PV Grid Generation. In the MCU, I designed the algorithm to create the functional SPWM by C programming for converting DC power to AC, meanwhile, the circuit gather some signal from the output to feedback, then the MCU adjust the parameter of SPWM. The main board, which was the most important circuit, amplified the SPWM with the Mosfet Bridge and rectified the output signal of the Bridge.
Also, I designed the overcurrent and low-voltage protection circuit.
