Thyristor And Diode Converters
Product Code : LSK-EPS-10526
Thyristor And Diode Converters (SKU LSK-EPS-10526), also described as the Thyristor and Diode Trainer, is a panel trainer for exploring the principles and applications of thyristors, diodes and converter circuits, including firing delay, harmonics and smoothing. It suits power electronics labs in B.Tech/B.E. electrical and electronics engineering and diploma courses. Science Lab Supplies ships it from Ambala, India to engineering colleges, polytechnics, tender contractors and distributors.
Specifications
The control panel carries mimic diagrams with shrouded sockets linking thyristors, diodes, inductors, transformers and smoothing capacitors. Multi-tapped transformers give single- and three-phase AC, a variable control delays the gate firing pulse, and analogue meters, a multi-function digital meter and an oscilloscope show the results.

Applications and Experiments for the Thyristor and Diode Converters
Students wire rectifier and converter circuits with shrouded leads, then vary firing delay and supply voltage while comparing gate pulses with output waveforms on the oscilloscope. This shows directly how firing angle, inductance and interphase transformers affect output voltage, ripple and harmonics.
- B.Tech power electronics lab: single- and three-phase diode rectifiers.
- Controlled rectifiers: effect of firing delay on output waveform and harmonics.
- Smoothing AC ripple with a load inductor and capacitors.
- Reducing circulating currents with a centre-tapped interphase transformer.
Circuits run from mains-derived AC; students should work only under supervision and with the supply off while rewiring.
Standard Scope of Supply
The trainer is supplied with its control panel and all listed components, the multi-tapped and interphase transformers, load inductor, meters, fast-blow fuses, transducers, an oscilloscope and a set of shrouded leads for connecting the circuits.
Packing, MOQ and Lead Time
A quotation can be drawn up for one trainer or for a full power electronics bench layout. It gives packing, delivery time and price for the number you need, and related engineering lab equipment in India can share the same quotation.
Science Lab Supplies, which holds an Importer-Exporter Code, can ship to buyers in Nepal, Bangladesh, Zambia, Rwanda, South Africa and Qatar. Write to us on the contact page, add the trainer to the enquiry cart, or open the lab tender page for tender terms.
Frequently Asked Questions
Is an oscilloscope included?
Yes. An oscilloscope is included, and transducers let students display and compare gate pulses with the output waveforms.
Can the thyristors be triggered externally?
Yes. Students can select either an internal or an external source to trigger the thyristor gates, and a variable control sets the firing delay.
Who supplies the Thyristor And Diode Converters trainer?
Science Lab Supplies supplies the trainer from Ambala, India, for college laboratories and for tender contracts.
What protects the circuits during experiments?
Fast-blow fuses on the control panel protect the load side of the experiment circuits, and the connections use shrouded sockets and leads.
