Abstract :
A kind of photovoltaic water-pump control system based on digital signal processor TMS320F2812 is designed. An improved P&Q method for maximum power point tracking of solar array is adopted. The utilization efficiency of solar array is improved by this way. Besides the perfect running and fully-digital controlling are achieved by U/f constant control method which is based on SVPWM modulation. The system has the characteristics of small volume, light weight, running stability and credibility and has the function of perfect protection.
