This study presents an innovative control framework designed for voltage source inverters (VSIs) equipped with LC output filters. The objective of this control framework is to reduce delay and suppress aliasing effects by employing multisampling techniques and implementing repetitive filtering methods. The multisampling approach can significantly reduce control delays, thereby enhancing both the bandwidth and stability margins of the system. The implementation of multisampling techniques for inverter voltage can enhance dynamic performance. However, it may introduce high‐frequency ripples in the control loop, resulting in low‐order aliasing harmonics and ultimately leading to output voltage distortion. To address this issue, a multiple notch filter with minimal phase delay is employed suppress aliasing. The optimal parameters of the system are determined by evaluating the filter specifications, filtering effectiveness, output voltage ripple, and overall system performance, while also considering the actual filtering requirements and circuit size. Its effectiveness and performance are carefully verified by experimental results.
