Single Phase Half Wave and Bridge Controlled Rectifier Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12933
Indian Lab Suppliers supplies the Single Phase Half Wave and Bridge Controlled Rectifier (Product ID: 12933) as part of its electronics engineering lab equipment range. It covers both the single-phase half-wave controlled rectifier and the fully controlled bridge rectifier, with UJT firing and a lamp load.
Quick Answer
Two UJT oscillators, each with a firing-angle potentiometer, fire the SCRs through two 1:1:1 pulse transformers. Students first connect one SCR as a half-wave controlled rectifier, then use all four SCRs as a bridge, and in each case observe how the output waveform and the brightness of the 40 W, 230 V lamp change with firing angle. Power comes through a 50 W, 230 V AC isolation transformer, and the firing circuits use a 9 V DC, 100 mA zener-regulated supply. It uses the same board components as the Single phase fully-controlled Bridge Converter (Product ID: 12892), with the half-wave experiment added. The board runs from 230 V ±10%, 50 Hz mains, and the lamp circuit is at mains voltage.
