摘要：

This paper presents design considerations of a new power supply and a new coil system for the vertical plasma position control in ADITYA-U tokamak. The main objective is to improve overall plasma performance compared to the existing open-loop system. Feedback stabilization of the plasma vertical position in ADITYA-U tokamak will play a vital role. Vertical Displacement Events (VDE) can be triggered during shaped plasma operation and requires proper control to avoid plasma disruptions. A radial magnetic field created by exterior coils will arrest the vertical plasma position against unwanted VDEs. Therefore, procurement of a new power supply namely, active position magnet control power supply (APMC-PS) is proposed to fulfill the vertical position control requirement in the ADITYA-U tokamak. This work presents the overall requirement for an active control system to improve the vertical control capability in the mid-size machine without passive stabilisers. The proposed scheme will support a reduction in time response with relatively less apparent power for controlling the vertical plasma position.
