| 英文摘要 |
| For the traditional dq current decoupling dual closed-loop control of single-phase cascaded H-bridge rectifier
is affected by the change of system inductance parameter, and to avoid the interference of system frequency offset, a
new direct power decoupling controller without inductance parameter and system angular frequency is proposed to realize
the independent control of active and reactive power. At the same time, it utilizes a cascaded delayed signal cancellation
algorithm to extract the fundamental positive sequence components and eliminate the effects caused by harmonic signals.
The proposed control method is validated by simulating a three-stage H-bridge rectifier in MATLAB/Simulink with low
DC-side voltage fluctuation, fast system response, and high harmonic suppression. |
