Single Phase Transistorised Bridge Inverter with Power Supply Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12905
Indian Lab Suppliers supplies the Single Phase Transistorised Bridge Inverter with Power Supply (Product ID: 12905) as part of its electronics engineering lab equipment range. It is a single-phase full-bridge inverter switched by four power NPN transistors, with opto-isolated drive for each switch.
Quick Answer
Two monostable multivibrator ICs, a quad XOR gate and a hex inverter generate the switching pattern, and a potentiometer adjusts it. Each of the four power transistors is driven through its own opto-coupler and transistor stage (twelve NPN and four PNP transistors in all), so diagonal pairs of the bridge switch alternately and the load sees alternating voltage. Separate regulated supplies are built in: three ±12 V DC at 30 mA for the isolated drivers, 12 V DC at 200 mA and 5 V DC at 100 mA. The board runs from 230 V ±10%, 50 Hz mains.

Frequently Asked Questions
Why are opto-couplers used?
The upper bridge transistors float, so their drive must be isolated from the control circuit.
How many power transistors are there?
Four power NPN transistors.
Why must the two transistors in one leg never conduct together?
That would short the DC supply (shoot-through).
