摘要
建立了采用四桥臂逆变器为主电路的三相四线制电力有源滤波器的数学模型。该电力有源滤波器基于滑模的控制策略,采用指数趋近律的方法以减少抖动的影响。Matlab仿真结果表明,基于滑模控制策略的三相四线制电力有源滤波器具有很好的谐波抑制性能。
The paper built the mathematic model of active power filter（APF） for three-phase four-wire system by use of four-legged inverter as main circuit.The APF is based on sliding mode control strategy,which uses the exponential reaching law to eliminate chattering.The simulation results in Matlab showed that the APF for three-phase four-wire system with the slide mode control strategy has good performance of harmonic suppression.
