【Abstract】 A photovoltaic water pump control system based on space vector pulse width modulation (SVPWM) was designed. The system adopted variable voltage variable frequency (VVVF) control based on SVPWM to realize high performance running of three-phase asynchronous motor and whole digital control. The hardware and software design was given. The experimental results show that the system has less output current harmonic distortion and runs stably and reliably.更多还原
