      It consists of the following modules.

      • Input module
      • Thyristor module
      • Regulation module
      • Output module
      • Excitation module
      • Indicating and operating module
      • Protection module

      4.a Input module

      The incoming 415V 3PH four wire supply will be brought into this module. It consists of -

      • Tripple pole and neutral incoming AC heavy duty isolator switch.
      • Three nos. HRC fuse link for mains.
      • Main contactor
      • Line surge suppressor consisting of capacitors, resistors & MOVs.

      4.b Thyristor module

      It will consist of three phase, full wave, fully controlled thyristor bridge assembly comprising of -

      • Six nos. derated thyristors each mounted on Aluminium heat sinks
      • RC Snubber circuit for power semi-conductors.
      • MOVs to protect thyristors against spikes.
      • Pulse transformers to isolate the control circuit from power circuit.
      • Forced cooling arrangement.

      4.c Regulation module

      It consists of modular glass-epoxy based printed circuit boards of height 4U with plug-in type gold plated connectors for easy replacement and servicing.

      These are green masked, legend printed PCBs housed in a card frame and interconnected by a mother PC Board. 

      The different blocks are as under.

      • Power supply and regulator.
      • Ramp generator with adjustable accn. Decn. Circuit.
      • Voltage and current control amplifier which controls the output voltage with adjustable voltage and current limiting.
      • Pulse amplifier feeding the pulse transformer primary and the gate trigger cirrcuits.
      • Tripping circuit for single phasing, phase sequence, under voltage, field failure and Electronic overload.
