For the problem of input voltage or current waveform to AC motor by inverter, an algorithm for effective value measurement of electric parameter was presented. Based on variable frequency speed control system for AC motor, it also presented the realization of the effective value measurement. Simulation results indicated the validity and feasibility of the proposed algorithm. It is necessary to popularize the measurement algorithm in engineering.
