| Abstract |
This paper presents a synchronous control method for a thyristor-controlled reactor (TCR) applied to a three-phase power system and verifies its power factor correction performance. To this end, the structure of a three-phase four-wire power system is analyzed, and a synchronization-based control strategy suitable for this system is developed. The proposed method is implemented using a Y-connected TCR, and its effectiveness is evaluated through both simulation and hardware experiments. The simulations were conducted using PSIM, while the hardware experiments were performed with a capacitive load configured using AC capacitors to create a leading power factor condition. The results confirm that the proposed synchronous control-based TCR improves the power factor effectively in a three-phase four-wire system. |
