| Abstract |
In this paper the cascade output voltage control of a unidirectional three-phase three-switch buck-type unity power factor PWM rectifier is discussed. Two control structures, i.e. an inner DC side inductor current control and an inner AC side input current and input filter capacitor voltage control are discussed. Guidelines for the control design which is nbased on a dynamically equivalent DC-to-DC converter model are given. Small signal transfer functions are derived by state space averaging. Finally, a comparative evaluation of the dynamics and of the realization effort of the control schemes is given and the continuation of the research is discussed. |
