PWM frequency conversion method

The invention provides a PWM (Pulse Width Modulation) frequency conversion method, which is used for solving the problems of current jitter and torque jitter of a permanent magnet synchronous motor at a specific rotating speed, calculating whether a carrier period Tsw can cause existence of low-freq...
