[Abstract]:With the aggravation of energy and environment problems, the use of new energy is becoming more and more urgent. Solar photovoltaic power generation has become an important part of the energy composition of the world because of its renewable, clean, inexhaustible and other advantages. The research of distributed small photovoltaic power generation system has become a hot spot. In this paper, a 600W photovoltaic inverter experimental platform is built, which is mainly studied from the following four aspects: the research content of this paper mainly includes the following points: 1: 1. On the basis of analyzing the basic working principle, equivalent circuit and mathematical model of photovoltaic cell, the principle of maximum power point tracking is studied in this paper, and several commonly used maximum power tracking control algorithms are compared and analyzed. A maximum power point tracking method based on temperature and intensity feedback is proposed, and the algorithm is simulated by Matlab. The simulation results show that the new maximum power point. 2. 2 can be quickly tracked when the external environment changes. The general scheme of photovoltaic off-grid inverter is designed, and the single-phase isolated two-stage inverter topology is adopted. The Boost circuit is used to charge the 48V battery on the front stage maximum power point experimental platform, and the push-pull circuit is used to boost the voltage from 48V to 360V and then invert to 220V.3via the full-bridge circuit. According to the technical specifications of the system, this paper selects various kinds of controllers. Finally, TMS320F2812 DSP and ARM S3C2440 are selected as main controller. TMS320F2812 DSP master controller drives the front Boost circuit and the rear stage full-bridge inverter circuit arm S3C2440 as the server. Users can log on to the ARM S3C2440 server using a Android phone to monitor the voltage, current and power of the photovoltaic system. Under the guidance of theoretical research and simulation analysis, the experimental waveforms of the front stage drive, the front stage boost, the rear stage drive and the rear stage inverter are given, and the mobile phone monitoring interface is given.
