Three Phase Fully Controlled Thyristorized Bridge Converter Manufacturer,Supplier and Exporter in India

Three Phase Fully Controlled Thyristorized Bridge Converter

Product Code : JA-PET-1443

The three phase fully controlled bridge converter trainer is a line-commutated six-thyristor bridge with its own triggering circuit. Cards with zero crossing detector, integrator, comparator and pulse generator set the firing angles of the positive and negative thyristor groups, and R and L loads, a freewheel diode and two 3½ digit panel meters are built in; the unit runs on 415 V, 50 Hz three phase mains (SKU JA-PET-1443).

Experiments on the three phase converter

The listed studies are:

  • Nature and generation of the control signal for a three phase full-wave controlled rectifier
  • Operation of the three phase fully controlled bridge rectifier with R load
  • Operation of the bridge rectifier with R-L load
  • Effect of the freewheeling diode on the output waveform

Scope of supply and ordering

The listing covers the three phase converter unit with its triggering cards, R and L loads, panel meters, patch cords and operating instructions, supplied by JaincoLab; a 415 V three phase supply is needed.

Frequently asked questions

How are the thyristor firing angles controlled?
Three identical cards, one per phase, with zero crossing detector, integrator, comparator and pulse generator control the positive group; a fourth card works with them for the negative group, and a potentiometer sets the firing angle.

Which loads are provided?
An R and L load with a load voltage divider, plus one freewheel diode for studying its effect on the output waveform.

What supply and instruments are needed?
Three phase 415 V, 50 Hz mains and a dual trace 20 MHz oscilloscope; unearthed mains sockets for the CRO are on the unit.
