Abstract:This paper introduces the design and implementation scheme of a new type of green energy power generation experiment platform. Based on C8051F120 as the control core, the experimental platform is a simulation device to achieve the realization of gridconnected voltage frequency and phase tracking by sampling the city power network signal. Using LCL filter made by inductance self winding to filter, the experimental platform is based on IGBT for single phase full bridge inverter main circuit to generate the sine pulse width modulation wave (SPWM) by means of software to achieve the maximum power point tracking (MPPT). The experimental platform has software and hardware automatic overcurrent protection and lowvoltage protection function. In addition, the hardware circuit of the system is simple and cost low, which provides guarantee for the practice of senior grades electrical majors under the condition of limited education funds.
