Description
Summary:An active power filter with single phase matrix converter topology is presented to reduce the THD of the input current, output current and output voltage of the system which is the main analysis in this paper. AC-AC converter topology switching strategy is used in the SPMC which is controlled by the current control closed-loop circuit or also known as active current wave-shaping technique. In order the AC-AC SPMC to operate and synthesize as an active power filter, the input supply current is being compensated by current control closed-loop circuit to produce the SPWM signal to be injected to the switches used which are the IGBTs. The work has been done using Matlab/Simulink simulation and the results are being compared to the same simulation done in open-loop method without using the active current wave-shaping technique.
