Advanced Vector Controller for a Four-Switch Three-Phase Rectifier under Unbalanced Grid Voltage
International Transactions on Electrical Energy Systems, 2022 One of the main challenges of a four-switch three-phase rectifier (FSTPR) is a DC imbalance in capacitor voltages. On the other hand, under unbalanced grid voltage conditions, unbalanced three-phase input current and the DC-link voltage affect the ...
