The paper presents a novel universal offset based PWM method for 3f ac-ac matrix converter, whose characteristics can be controlled by the offset regulation. Typical characteristics of the offset based PWM control for the matrix converter will be described. The proposed PWM algorithm may help to simplify further study of PWM techniques for ac-ac matrix converter. Different variants of the offset functions for unity input power factor will be presented. The theoretical analysis will be verified by experimental results.
