Product Code : SCL-EELE-12829
Indian Lab Suppliers supplies the MOSFET, IGBT, Transistor & SCR based Step Down Chopper (Product ID: 12829) as part of its electronics engineering lab equipment range. It is a trainer for step-down (buck) DC choppers built with four different switching devices: MOSFET, IGBT, transistor and SCR.
Quick Answer
A triangular-comparator PWM circuit varies the switching frequency from about 27 Hz to 5 kHz and the duty ratio from 0 to 90%. Each of the four switches, a 55 V / 49 A MOSFET, a 600 V / 10 A IGBT, a 100 V / 5 A power transistor and a 600 V / 16 A SCR, can be run as a step-down chopper with R, RL or motor load, giving twelve chopper experiments plus the PWM circuit study. The motor load is a 24 V, 0.5 A geared DC motor running at 100 rpm. It works from 220 V or 110 V, 50/60 Hz, with four test points and 2 mm sockets.
