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.
