摘要：

The paper proposes a method of active switching harmonics current reduction in the dc-link capacitor of a two-level, three-phase, back-to-back converter. Based on the derived analytical solution for switching harmonic currents in the dc-link, it is shown that by specific control over the pulsewidth-modulated (PWM) carriers' phase angles, the targeted harmonics of the rectifier and the inverter can be synchronized in phase such that their cancellation occurs in the dc-link capacitor. This synchronization is provided by harmonic phase feedback control. A three-step procedure to implement the method is detailed in the paper. The effectiveness of the proposed approach is verified experimentally.
