A new output voltage control method for PWM‐controlled cycloconverters with space vectors is proposed in this paper. Results are as follows:. (1) The classification and the systematic behavior of the space vectors of PWM‐controlled cycloconverters are clarified through the analysis. (2) A new output voltage control method that makes excellent output voltage waveforms is proposed using the results of this analysis. (3) Feasibility of the proposed output voltage control method is confirmed by simulation. (4) Output voltage waveforms of the PWM‐controlled cycloconverters are compared with those of the PWM‐controlled inverters, using the performance index of variance of time‐integral of higher harmonic components. Therefore, the proposed control method may reduce both acoustic noise and torque ripple of induction motors.
