Product Code : SCL-EELE-12899
Indian Lab Suppliers supplies the Single phase PWM Converter with Power Supply (Product ID: 12899) as part of its electronics engineering lab equipment range. It demonstrates a single-phase converter whose output is controlled by pulse-width modulation of a power transistor.
Quick Answer
A timer, an op-amp, a UJT and XOR and inverter logic gates generate the switching pulses, and two NPN transistors drive an NPN power transistor that switches the converter into the on-board load. Three potentiometers adjust the control settings, so students can see how changing the pulse width changes the output. Supplies are 6 V AC and 30 V AC at 100 mA and ±12 V DC at 100 mA regulated, and the board runs from 230 V ±10%, 50 Hz mains. An oscilloscope is needed to view the PWM waveforms.
