All three boards run on three-phase 415 V, 50 Hz mains and carry two 3½-digit panel meters. Choose this one to study the basic diode bridge, whose output is set by the supply; the thyristor boards are the ones for courses that go on to firing-angle control of the output.
What Is the Three Phase Full Wave Rectifier Used For?
A three-phase full-wave bridge uses six diodes, two on each phase line. At any moment the diode on the most positive line and the diode on the most negative line conduct, so the DC output is built from six pulses in every supply cycle and is far smoother than the output of a single-phase rectifier. Bridges of this kind supply the DC in industrial power supplies, battery chargers and motor drives. Science and engineering students use the board to see the six-pulse output on an oscilloscope and to read the DC voltage and load current with the resistive load connected.
What to Specify When Ordering
- Quantity — the number of rectifier boards for the lab.
- Oscilloscope and isolation transformer — whether either should be quoted with the boards.
- Companion boards — the half- or fully-controlled three-phase converters if the course continues to thyristor bridges.
Frequently Asked Questions
Why is a three-phase bridge output smoother than single-phase?
Because the six diodes hand over conduction six times per supply cycle, the output ripple is at six times the supply frequency and its dip between peaks is small. A single-phase full-wave rectifier gives only two pulses per cycle, with much deeper ripple.
What supply does the board need?
A three-phase 415 V, 50 Hz AC mains supply. The board has a four-pole MCB, a 3-pole power connector with AC coil and push-to-ON switch, and a three-phase socket rated 415 V, 50 Hz, 20 A.
What other apparatus is required?
A 20 MHz dual trace cathode ray oscilloscope, used unearthed, and a 50 W isolation transformer for unearthing it. JLab’s Dual Trace Oscilloscope is available as a separate item and can be quoted on the same enquiry.
How does this board differ from the thyristor bridge converters?
It uses six diodes, so its output is fixed by the supply rather than by a firing angle; the half- and fully-controlled converters use thyristors whose firing angle is set by a potentiometer. The table above lists their other differences.
What should an export enquiry include?
The number of boards, the destination country and port or city, the delivery terms you need (for example FOB or CIF), any packing or labelling instructions and the tender reference if one applies.
Who manufactures the Three Phase Full Wave Rectifier board?
JLab (Jain Laboratory Instruments Pvt Ltd) makes it at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an engineering lab equipment manufacturer in India whose range covers power electronics trainers from single-phase boards to three-phase rectifiers and converters. It was incorporated in 2017 and is based on Hargolal Road, Ambala, Haryana. The rectifier board is built at JLab’s own works and not bought from a trader, so colleges, institutes, dealers and importers buy direct from the manufacturer, every board is visually inspected before dispatch, and repeat orders are made by the same works. JLab exports worldwide and ships to buyers in every region — for example the Philippines in Southeast Asia, Sweden in Northern Europe, Romania in Eastern Europe, Hong Kong in East Asia and Zimbabwe in East Africa. Tender details are published on the JLab lab tenders page.
