Hardware Realization of Multilevel Inverter-based Active Power Filter

Abstract

This paper presents the development and implementation of multilevel inverter (MLI)-based active power Alter (APF) using DSP of dSPACE. Implementation of MLI for APF in high-voltage system eliminates use of bulky and high-cost transformer to connect APF. This algorithm, to generate switching signal of devices, is developed in MATLAB SIMULINK. The reference signals of APF are generated by using instantaneous reactive power (p-q) theory. Carrier phase-shifted pulse width modulation (CPS-PWM) scheme is implemented to generate switching signals which reduces the individual device switching frequency. Experimental results of prototype model are presented under different loading conditions to investigate the steady-state and transient performance of the APF.

Keywords:

• Active power filters
• Carrier phase-shifted pulse width modulation
• Multilevel inverter
