Abstract: “The ‘Neutron Generator Facility’ is operational at PURNIMA, BARC. The Neutron Generator is a 300KeV electrostatic DC accelerator. A 400 kV, 10mA DC power supply is being used for acceleration of deuteron beam. The HV power supply generates 400 kV from 3 phase Mains. The basic logic to generate 400 kV consists of following stages: Three phase Mains → Three phase Converter → High Frequency Inverter → Step-Up Transformer → Balanced CW Multiplier. The converter is controlled by SCR firing card & Converter control card and Inverter Protection Card controls the Inverter. Present project is to design a new PC based control system for SCR Firing, Converter & Inverter circuit to provide local and remote operation”
