Abstract
The 200 kW generator is designed and developed for ion cyclotron resonant heating (ICRH) experiments on Aditya Tokamak and 1.5 MW stage for SST-1 (steady-state super-conducting tokamak 1). The 200 kW stage uses 4CM 300,000GA tetrode. An existing DC power supply capable of delivering 30 kV, 20 A has successfully reconfigured with necessary protections and controls. This is being used for ICRH experiments in Aditya tokamak. screen grid power supply of 1 kVDC, 1 amp, filament power supply of 18 VAC, 430 Amp, have been developed in-house, while the control grid power supply is procured indigenously. High voltage power supplies for the pre-driver stage (2 kW), driver stage (20 kW) have been designed and commissioned along with necessary protections. All the high voltage and auxiliary power supplies can be operated and controlled in manual or remote mode through data acquisition and control (DAC) system. The existing 200 kW system would be augmented with the 1.5 MW stage for experiments on SST1 tokamak This paper presents the details of auxiliary and high voltage power supplies that are developed in house for 200 kW stage. The monitoring and arc protection circuits are described. Results of the wire-burn test are highlighted.
