Abstract :
A multilevel PWM (pulse-width-modulated) voltage source inverter, especially a five-level one, is introduced to obtain a static VAr compensator (SVC) as a large-scale power source. The three phase SVC is modeled using circuit DQ transformation and completely analyzed including DC and AC characteristics. Through experimental results for a 5 kVA SVC, the validity of the analyses and the feasibility of the VAr compensation system are shown for high-power applications
