چکیده
A circuit of a multi-phase active power filter based on multi-stage inverter architecture was introduced. The paper is focused on building the MATLAB / Simulink model of an AC power supply system including a single-phase active power filter with a two-stage inverter. Each stage of the filter uses the pulsewidth modulation (PWM) method. The results confirmed high efficiency of such a compensating circuit. The presented model will be used for the verification of the bridge-element concept, enabling computer modelling of multi-phase bridge converters, for any number of electrical phases. Key-Words: Electric power supply system, Active power filter, Mathematical modelling, Multi-stage inverter, Power quality, Electromagnetic compatibility.
