What Is the Triac and AC Phase Control Board Used For?
A TRIAC is a bidirectional thyristor that conducts in both half-cycles of the mains, so a single device can control the full AC power to a load such as a lamp. A DIAC in the gate circuit breaks over at a definite voltage in either direction and delivers a sharp trigger pulse, which makes the pair the basis of the ordinary light dimmer. The board is used in power electronics practicals in diploma and degree courses in electrical and electronics engineering. Experiments that can be performed:
- TRIAC characteristics and operation in all four modes: I+, I−, III+ and III−
- Gate control of the TRIAC with an NPN transistor
- Gate control of the TRIAC with a PNP transistor
- Phase control with the TRIAC and a DIAC as pulse generator for gate trigger
- TRIAC light dimmer: hysteresis effect and its minimisation by the gate slaving technique
- Radio frequency interference (RFI) in phase control and its suppression by an RFI filter
What to Specify When Ordering
- Other apparatus — the multimeter, regulated power supply and oscilloscope are separate items; name the ones you need on the enquiry.
- Companion boards — the Training Board for Triac or the SCR phase control board if the course covers them.
- Quantity — the number of boards for your lab.
Frequently Asked Questions
What are the four triggering modes of a TRIAC?
Modes I+ and I− are with main terminal MT2 positive with respect to MT1 and a positive or negative gate current; III+ and III− are with MT2 negative and a positive or negative gate current. The board lets each mode be studied.
What is the hysteresis effect in a TRIAC dimmer?
In a simple DIAC-TRIAC dimmer the lamp switches on at a different control setting from the one at which it goes off, because once the DIAC fires it partly discharges the timing capacitor, which changes the starting voltage for the next half-cycle. The board demonstrates the effect and its minimisation by gate slaving.
Why does phase control produce radio frequency interference?
The TRIAC switches the load current on abruptly part-way through each half-cycle, and the fast edges contain high-frequency components. The RF choke and capacitor on the board form a filter that suppresses this interference.
What other apparatus is needed?
A 3¾-digit digital multimeter, a 0–30 V, 1 A IC-regulated power supply and a 20 MHz dual trace cathode ray oscilloscope used unearthed. They are separate items that can be quoted together with the board.
What information is needed for an export quotation?
Send the number of boards, the destination country and port or city, the delivery terms you prefer (for example FOB or CIF), packing or labelling requirements and any tender reference.
Who manufactures the Triac and AC Phase Control board?
Jain Laboratory Instruments Pvt Ltd (JLab) builds it at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian maker of power electronics and electrical engineering trainers, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. This board is produced in JLab’s own works rather than bought from a trader, so engineering colleges, dealers and importers order it from the manufacturer, each unit is visually inspected before dispatch, and repeat orders are handled by the same team. JLab exports worldwide and ships to buyers in every region — for example Mauritius in East Africa, Lesotho in Southern Africa, Canada in North America, Norway in Northern Europe and Cyprus in Southern Europe. Tender information is on the JLab lab tenders page.
