LCL滤波PWM整流器的新型准直接功率控制
Novel quasi direct power control for LCL-based PWM rectifier
摘要
Abstract
The LCL filters cause resonance and need active damping control. In order to solve the problem, a novel quasi direct power control scheme for three-phase LCL-based PWM rectifier is proposed based on the derivation of relationship between the power and the current. The AC-side control system includes two loops—an outer power loop and an inner current loop. The power loop provides current command for the current loop. Capacitor current feedback is used in the current loop for active damping. The control system structure is introduced and detailed design procedure of the controller is analyzed. The proposed method has clear principle and is easy to implement. The simulation results show that the system is stable, the resonance is suppressed, the AC-side currents are highly sinusoidal with a power factor close to 1, and the system has excellent steady state performance and transient performance.关键词
