Product Code : EL-PET-1437
Jlab Export is a leading Single Phase Series Inverter Manufacturer,and suppliers in India
Single Phase Series Inverter (code EL-PET-1437) is a power electronics training board for studying how a single-phase series inverter converts DC into AC. The circuit on its panel is built around two silicon controlled rectifiers (SCRs), two 1:1 pulse transformers and a centre-tapped inductor. Jain Laboratory Instruments Pvt Ltd (JLab) produces the board at its manufacturing works in Ambala, India.

What Is the Single Phase Series Inverter Board Used For?
An inverter turns a DC supply into AC. In a series inverter the load is connected in series with a resonant circuit, so the current through the conducting SCR rises, swings back to zero and lets that thyristor turn off by itself; firing the two SCRs alternately then drives current through the load first in one direction and then in the other. Science and engineering students use the board to study this self-commutating action, adjusting the inverter frequency with the potentiometer and watching the resulting waveforms at the panel terminals on an oscilloscope.
What to Specify When Ordering
- Quantity — how many boards the power electronics lab needs.
- Oscilloscope — whether one should be quoted together with the boards.
- Related boards — any commutation, chopper or inverter trainers to be added to the same enquiry.
Frequently Asked Questions
How does a series inverter turn its SCRs off?
By load commutation. The resonant series circuit makes the current in the conducting thyristor fall naturally to zero, after which the SCR regains its blocking state without any separate turn-off circuit. This is the self-commutation method usually taught as class A commutation.
Why is the inverter frequency kept below the resonant frequency?
Each SCR needs its current to reach zero, and a short recovery time after that, before the other SCR is fired. If the second thyristor were triggered too early, both would conduct together and short the DC supply, so a basic series inverter is run at a frequency below the ringing frequency of its resonant circuit.
What other apparatus is required?
A 20 MHz dual trace cathode ray oscilloscope, used unearthed. JLab offers a Dual Trace Oscilloscope as a separate instrument, which can be quoted on the same enquiry.
How does it differ from the DC To AC Inverter board?
This board works from 230 V mains, makes its DC voltage with a bridge rectifier and switches it with two SCRs in a series inverter. The DC To AC Inverter studies a multivibrator circuit with NPN transistors and is operated from a 12 V, 80 Ah battery.
What should an export enquiry state?
The number of boards, the destination country and port or city, the delivery terms you want (such as FOB or CIF), any packing or labelling instructions and a tender reference where there is one.
Who manufactures the Single Phase Series Inverter board?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian manufacturer of engineering lab equipment, including power electronics trainers, incorporated in 2017 with its base on Hargolal Road, Ambala, Haryana. The series inverter board comes from JLab’s own works rather than being bought in from a trader, so colleges, training institutes, dealers and importers buy from the source, every board is visually checked before dispatch and repeat orders are made by the same team. JLab exports worldwide and ships to buyers in every region — for example Guyana in South America, South Africa in Southern Africa, Italy in Southern Europe, Hungary in Eastern Europe and Singapore in Southeast Asia. The JLab lab tenders page has information for tender purchases.
