Study on Photovoltaic Pump Power Supply Based on Space Vector Pulse Width Modulation

Aiming at the characteristics of photovoltaic pump system. A power supply of photovoltaic pump is designed, which can drive general pump. The control strategy of this system is discussed. The principle of space vector PWM and true maximal power point tracking are analyzed by digital signal controllers dsPIC2010. Software of system are worked out and related experimental results are achieved.
