Thyristor and Diode Converters
Thyristor and Diode Converters (Product Code: SLE/EPS/07) is a power electronics trainer used to build and study diode and thyristor rectifier circuits in electrical and electronics engineering laboratories. Students patch thyristors, diodes, inductors, transformers and smoothing capacitors together on a mimic-diagram panel, then compare gate pulses with output waveforms on the oscilloscope included with the set. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM, at its own factory in Ambala, India.

What Are Thyristor and Diode Converters Used For?
This trainer teaches how AC is converted to DC — first with uncontrolled diode rectifiers, then with thyristor circuits whose output depends on when the gates are triggered. Students select single-phase or three-phase AC from the multi-tapped transformers, wire each rectifier circuit on the mimic panel, and measure currents and voltages on the analogue meters and the multi-function digital meter.
Two parts make classic effects visible: the load inductor shows how inductance smooths AC ripple, and the centre-tapped interphase transformer shows how circulating currents in rectifier circuits are reduced. Through the transducers, the included oscilloscope displays gate pulses beside the output waveform, whether triggering comes from the internal or an external source. A good habit is to start each new circuit at a low AC supply voltage, set on the lower panel, and raise it once the wiring is checked.
What to Specify When Ordering
- The single-phase and three-phase mains supply available in your laboratory.
- Number of trainers needed for your student groups.
- Whether you need extra shrouded leads or replacement fast-blow fuses — ask us.

Frequently Asked Questions
What components are on the Thyristor and Diode Converters trainer?
The Thyristor and Diode Converters trainer (SLE/EPS/07) provides thyristors, diodes, inductors, transformers and smoothing capacitors on a control panel with clear mimic diagrams and shrouded sockets. Students connect them with shrouded leads to build different rectifier circuits.
Is an oscilloscope included with the Thyristor and Diode Converters?
Yes. An oscilloscope is included with the Thyristor and Diode Converters trainer. Transducers let students connect it to show and compare the thyristor gate pulses with the output waveforms of the circuits they build.
Which AC supplies can the circuits use?
Multi-tapped transformers in the Thyristor and Diode Converters trainer give a choice of single-phase and three-phase AC voltages for connection to the diodes and thyristors. Controls on the lower panel adjust the AC supply voltage and ballast resistance during experiments.
How are the thyristor gates triggered?
For thyristor experiments on the Thyristor and Diode Converters trainer, students select either an internal or an external source to trigger the thyristor gates, then compare the gate pulses with the output waveform on the included oscilloscope.
How are the experiment circuits protected?
Fast-blow fuses on the control panel of the Thyristor and Diode Converters trainer protect the load side of experiment circuits, and all connections use shrouded sockets and leads. Ask ScienceLab about replacement fuses when you order.
Who manufactures the Thyristor and Diode Converters trainer?
The Thyristor and Diode Converters trainer is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory in Saha, Ambala, Haryana, India, and supplied factory-direct to institutions and dealers in India and international markets.
Can a calibration certificate be supplied for the meters?
Whether a calibration certificate can be supplied for the meters of the Thyristor and Diode Converters trainer should be discussed with ScienceLab before you order. Mention it on our contact page with your quantity and supply details.
