A novel smart compensator for energy/power quality enhancement of nonlinear loads

摘要

The paper presents a novel flexible smart compensator converter scheme for energy utilization enhancement and/or power quality harmonic ripple control. The converter topology is flexible and can be controlled by pulse width modulation (PWM), pulse frequency modulation (PFM) or a combined PWM/PFM switching strategy to ensure power quality enhancement and better energy utilization of nonlinear cyclical arc or inrush type electric loads. This includes large industrial induction motors, robotic drives, industrial arc-furnaces, and fluorescent industrial commercial lighting schemes.
