Thyristor And Diode Converters
Product Code : LSK-EPS-10526
Thyristor And Diode Converters (SKU LSK-EPS-10526), also called 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. Engineering colleges, polytechnics, tender contractors and distributors can request it from Science Lab Supplies, which prepares quotations in Ambala, India.
Specifications
Each feature of the thyristor and diode trainer appears on its own table row. In short, a mimic-diagram panel with shrouded sockets links thyristors, diodes, inductors, transformers and smoothing capacitors, with adjustable gate firing delay, single- and three-phase AC from multi-tapped transformers, meters and an included oscilloscope.

Applications and Experiments for the Thyristor and Diode Converters
With the trainer, students can 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, showing how firing delay, inductance and interphase transformers affect output voltage, ripple and harmonics.
- B.Tech power electronics lab: single- and three-phase diode rectifiers fed from multi-tapped transformers, a tapping principle the Three Phase Mobile Transformer also shows.
- 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 the components above, 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, plus the lower-panel controls for AC supply voltage and ballast resistance.
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. For a power electronics bench, a short note on the contact page or an entry in the enquiry cart starts the quotation; tender terms are explained on the lab tender page.
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. For other benches, the separate Oscilloscope with colour display can be quoted.
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 delays the gate firing pulse to show its effect on harmonics and waveforms.
Who supplies the Thyristor And Diode Converters trainer?
Science Lab Supplies, located in Ambala, India, prepares the quotation for this power electronics trainer, whether it is for a single college laboratory or part of a larger tender contract.
What protects the circuits during experiments?
Fast-blow fuses on the control panel protect the load side of the experiment circuits, and students connect the parts using the included shrouded leads in the shrouded sockets of the mimic-diagram panel.
