Model based current mode control design and experimental validation for a $$3\phi$$ 3 ϕ rectifier under unbalanced grid voltage conditions

Abstract: This paper addresses the control design and the experimental validation of a current mode control for a three phase voltage source rectifier. The proposed control law is able to fulfill the voltage regulation and the current tracking control objectives despite of unbalanced and distorted grid voltages. The proposed control law consists of two loops, which are referred as inner tracking loop and the outer voltage regulation loop. The inner loop is designed to provide damping to the system, which also includes a… Show more

“…When studying the current imbalance problem of parallel erected lines, it is assumed that the power at the transmission end, power supply and load end parameters of the line are symmetrical. Using accurate line parameter models to simulate overhead lines, the load impedance can be calculated based on the line delivered power and power factor [14,15]. According to the requirements of the electromagnetic transient calculation program, double circuit transmission line network is simplified, and the simplified system wiring is shown in Figure 2.…”
