| Sumario: | Active Power Filters (APF) for reducing current harmonic distortion have been widely used in both grids and microgrids. This work proposes a topology for an APF consisting of two Voltage Source Inverters (VSIs) connected in parallel to the same DC-link, which saves space and reduces cost compared to independent APFs. One inverter operates at a low switching frequency and compensates for low-order harmonics. The second inverter operates at a high switching frequency to target high-frequency harmonics. As the high-frequency inverter handles only around 25% of the total RMS current managed by the overall APF, switching losses are significantly reduced. However, connecting inverters in parallel produces circulating currents that can have an adverse effect on the system. In this work, circulating currents are cancelled by controlling the zero-sequence component of the currents in the two inverters. |
