摘要：
An improved controller for minimum dc-link-voltage control is proposed. due to its adaptive minimum dc-link voltage characteristic, it can obtain the better compensation performances, and also the minimum dc-link voltage control with self-charging process can be obtained as well as providing the dynamic harmonic currents, it has better dynamic and static characteristics. In order to make an accurate design of the proportional and integral gains, the design procedures of the improved minimum dc-link voltage controller are discussed in detail. Finally, representative simulation and experimental results in a three-phase four-wire center-split shunt APF are presented to verify the validity and effectiveness.
