Description: : Random pulse width modulation speed control system to solve the exchange of acoustic noise in a direct and effective way. Random zero vector distribution is a good random method, but the asymmetrical switching function so that it does not apply to the traditional current sampling methods. PWM cycle through the simulation shows that the mid-point sampling methods can not be an accurate, on average, the analysis of asymmetric mode ripple current caused by the impact on the current average value based on the proposed distribution of a suitable RZV current sampling methods. The simulation results confirmed that the method is simple and feasible.
