Single Phase Cycloconverter Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12804
Indian Lab Suppliers supplies the Single Phase Cycloconverter (Product ID: 12804) as part of its electronics engineering lab equipment range. It generates eight line-synchronised, isolated trigger pulses for SCRs in centre-tap and bridge single-phase cycloconverters.
Quick Answer
A cycloconverter produces a lower output frequency directly from the AC supply by switching groups of SCRs. This unit uses a ramp-comparator and counter scheme on a 89C2051 microcontroller: a thumbwheel switch divides the 50 Hz line frequency by 1 to 10 (position 0 gives 10), and a graduated potentiometer sets the firing angle from 180° to 0°. Outputs T1–T4 serve a centre-tap transformer cycloconverter, while T1/T1′ to T4/T4′, isolated from two secondaries of the same pulse transformer, serve a bridge type. Gate drive is 200 mA, triggers have soft start and stop, and nine test points show the firing logic. It works directly on 230 V AC mains and can also fire single-phase converter experiments. Please confirm at quotation whether the SCR power circuit and transformer are included.

Frequently Asked Questions
What output frequencies are possible?
The 50 Hz line frequency divided by 1 to 10, from 50 Hz down to 5 Hz.
Why are T1 and T1′ separate?
They come from two isolated secondaries of one pulse transformer, so two SCRs at different cathode potentials in a bridge can be fired together.
Can it fire other converters?
Yes, it can be used as a single-phase converter firing unit.
