D.C. Step down MOSFET Chopper with Power Supply Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12922
Indian Lab Suppliers supplies the D.C. Step down MOSFET Chopper with Power Supply (Product ID: 12922) as part of its electronics engineering lab equipment range. It is a step-down (buck) DC chopper switched by a MOSFET, with adjustable switching frequency and duty cycle.
Quick Answer
A triangular-wave generator IC and a MOSFET driver IC produce the gate signal, and two potentiometers set the chopping frequency and the duty cycle. The MOSFET chops the 20 V DC, 1 A regulated supply, so the average output equals the duty cycle times the input voltage, and students can confirm this relation with meters and an oscilloscope. A ±12 V DC, 100 mA regulated supply powers the control circuit, and the board runs from 230 V ±10%, 50 Hz mains. A load is not listed in the specification; please confirm it at quotation.
