A flying capacitor multilevel PWM converter based UPFC [PDF]
2001 IEEE 32nd Annual Power Electronics Specialists Conference (IEEE Cat. No.01CH37230), 2002 The paper presents a unified power flow controller (UPFC) based on the flying capacitor (FC) multilevel voltage source converter (VSC) with phase-shifted sinusoidal PWM control. The topology allows high power handling, low power loss, low harmonic distortion and hence less filtering requirement.
