Abstract
The majority of industrial controlled induction machine
drives are connected to the mains via a diode bridge. However, if reduction of harmonic currents and / or regenerative operation is desired, replacing the diode bridge by an active front-end (AFE) is
required. This paper describes two models of an AFE: a power balance model disregarding switching effects,and an ideal switching model of a pulse width modulation (PWM) converter. Both models are controlled
utilizing space phasors in a voltage oriented reference frame. Voltage oriented control (VOC) of the mains converter can be compared with field oriented control (FOC) of a machine converter. Design and parametrization of the main parts-synchronization
with mains voltage, current controller and DC voltage controller-are described in detail. Additionally,simulation results proving the implementation and demonstrating possible investigations as well as an outlook on further enhancements are presented.
