| Abstract: |
| A novel HPF(Hybrid Power Filter) is presented for harmonics suppression and reactive power compensation and its topological structure and working principle are introduced. For its operational requirements,a novel current source control strategy is proposed and its three cases are analyzed:closed loop,open loop and complex control strategy. The control characteristics under three conditions are discussed in detail. It is concluded that,the complex current control strategy can obtain the best operational perf... |
