Choose this board to study a transistor inverter of the kind used in battery backup supplies; the series inverter board is the one for a thyristor inverter with self-commutation.
What Is the DC To AC Inverter Board Used For?
Inverters let a battery run equipment that needs AC, as in home backup supplies, vehicles and solar systems. In the circuit studied here a multivibrator produces the alternating drive signals and the transistor stages turn the battery’s DC into AC. Battery inverters commonly switch the current alternately through the two halves of a centre-tapped transformer winding, and the transformer raises the voltage to the level the load needs. Science and engineering students use the coloured test points to check the wave shape and amplitude of the pulses at each stage on an oscilloscope.
What to Specify When Ordering
- Quantity — the number of inverter boards needed.
- Companion boards — for example the series inverter or the MOSFET chopper for the same course.
- Oscilloscope — whether one should be quoted with the boards.
Frequently Asked Questions
What is the multivibrator used for in an inverter?
A multivibrator is an oscillator that switches between two states, giving two alternating square-wave outputs. In an inverter these outputs drive the switching transistors alternately, so the current in the transformer reverses each half cycle and an AC voltage appears at the output.
Why are both low-power and high-power transistors used?
In a transistor inverter the drive signals from the oscillator ICs can supply only a small current, so low-power transistors are commonly used as drivers and high-power transistors switch the much larger current drawn from the battery.
Why do battery inverters use a transformer?
A low-voltage battery cannot drive mains-voltage equipment directly. The transformer steps the switched low voltage up to the level the load needs, and a centre-tapped winding lets two switching stages take turns driving it.
What other apparatus is required?
A 12 V DC, 80 Ah battery (any car battery can be used) and a 20 MHz dual trace cathode ray oscilloscope, used unearthed. JLab’s Dual Trace Oscilloscope is a separate item that can be quoted on the same enquiry.
What should an export enquiry give?
The number of boards, the destination country and port or city, the delivery terms (for example FOB or CIF), packing or labelling instructions and the tender reference if there is one.
Who manufactures the DC To AC Inverter board?
Jain Laboratory Instruments Pvt Ltd, known as JLab, 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 and power electronics trainer manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The inverter board is made at JLab’s own works rather than bought in from a trader, so colleges, institutes, dealers and importers obtain it straight from the maker, each board is visually inspected before dispatch and repeat orders are handled by the same works. JLab exports worldwide and ships to buyers in every region — for example Spain in Southern Europe, Moldova in Eastern Europe, Sierra Leone in West Africa, Norway in Northern Europe and Tunisia in North Africa. For tender purchases, see the JLab lab tenders page.
