Step down & Step up transistor chopper Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12924
Indian Lab Suppliers supplies the Step down & Step up transistor chopper (Product ID: 12924) as part of its electronics engineering lab equipment range. It is a transistor chopper board that works as both a step-down and a step-up DC converter.
Quick Answer
An IC triangular-wave generator and an op-amp produce the switching pulses for the transistor, and the circuit is connected either as a step-down chopper, where the average output is below the 12 V supply and follows the duty cycle, or as a step-up chopper, where the 40 mH choke stores energy during each on-period and releases it at a higher voltage. A 12 V DC motor and a 230 V, 15 W lamp serve as loads, so students can see the output change with duty cycle in each mode. Supplies are 12 V DC at 1.5 A and −12 V DC at 200 mA, IC regulated, and the board runs from 230 V ±10%, 50 Hz mains. The step-up output can reach a hazardous voltage, so switch off before changing connections.
