This paper presents the performance analysis of a Unified Power Quality Conditioner (UPQC) with transformation less Combined Mode Control (CMC) approach. DSP controller TMS320LF2407A is used to realize the switching pulses for the APFs of UPQC. The %THD of load voltage and source current has been considered as a measure for assessing the performance. The experimental results confirm the satisfactory operation of UPQC in mitigating the harmonics. Keywords- Power Quality, Unified Power Quality Conditioner( UPQC), Series Active Power Filter (SAPF), Shunt/Parallel Active Filter (PAPF), Voltage Source Inverter (VSI), Hysteresis Control, Sinusoidal Pulse Width Modulation (SPWM), DSP Controller.
