Abstract : This paper presents harmonic and power quality analysis of two level and three level Diode Clamped Voltage
Source Inverter (DCVSI). Purpose of analysis is to investigate performance of VSI in WECS in terms of power quality fed to
grid, filter requirement and DC bus utilization. Modulation strategy used is Space Vector PWM (SVPWM) for two levels
and three levels DCVSI as it is readily available for digital implementation. Performance evaluation of VSI is measured
through Weighted Total Harmonic Distortion (WTHD), IEC 1000-3-4 Regulation and Filtering Ratio (FR). Voltage Source
Inverter and LCL filter are modeled in terms of switching function and state space technique respectively. These models
integrated and simulated using MATLAB-SIMULINK. It is observed from simulation that DCVSI has better WTHD and
higher DC Bus Utilization. Further it is also observed that DCVSI experiences lower switching loss and less filtering
requirement.
