摘　　要：本文对光伏直驱空调同步空间矢量调制(SVPWM)算法进行研究,给出同步调制的实现方案,并通过仿真验证该同步调制实现方案的有效性。最后通过在永磁同步电机矢量控制系统中应用SVPWM调制,验证了该调制方法在低开关频率的闭环控制中的稳定性。This paper studies the synchronous space vector modulation(SVPWM)algorithm of photovoltaic direct-drive air conditioners,and gives the implementation scheme of synchronous modulation.And the effectiveness of the synchronous modulation scheme is verified by simulation.Finally,by applying SVPWM modulation in the vector control system of permanent magnet synchronous motor,the stability of the modulation method in closed-loop control with low switching frequency is verified.
