To achieve the maximum current rising rate, second-generation Experimental Advanced Superconducting Tokamak (EAST) plasma vertical displacement active feedback power supply applies voltage control mode while retaining the first-generation current tracking mode. When the power supply outputs high voltage, the accompanied frequent over-current protection will return the power to DC side, which leads to over-voltage protection, so the current limiting protection is applied. Experimental results prove that the voltage mode can greatly improve the ability to suppress vertical unstable displacement of plasma.
