This paper describes a method of determining parameters of PWM rectifiers based on the degrees of total harmonic distortion (THD). The inductance value of ac reactors and the capacitance value of the dc capacitor have a great influence on the amplitude of the harmonics in the ac input currents and dc output voltage, respectively. So far, simulation‐based harmonic analysis is dominant. Here, the harmonic distortion determining factor is proposed that provides a simpler and broader manner of obtaining THD values, that is, it enables approximate THD values to be calculated without conducting any simulations or experiments. Finally, an experiment using a DSP is carried out to confirm the usefulness. An optimal regulator theory is applied to the controller design.
