Abstract: 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.

Key words: synchronous modulation, SVPWM, permanent magnet synchronous motor, vector control
