Abstract

A control method of current type PWM AC-to-DC converters which realize sinusoidal AC input current and unity power factor is discussed. In such a type of converter, an LC filter required on the AC side may cause a resonant problem especially in the transient condition. To overcome this problem, state feedback control is introduced, and a control strategy which is suitable for the DC output current control as well as the AC side current control is proposed. Circuit parameters and feedback coefficients in the AC side current control system are optimized on the basis of an analysis in which the system is treated as a sampled data system. This system is applied to current pattern control of a reactor.<>
