Single Phase PWM Inverter Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12800
Indian Lab Suppliers supplies the Single Phase PWM Inverter (Product ID: 12800) as part of its electronics engineering lab equipment range. It demonstrates a single-phase PWM firing circuit driving H-bridge inverters built with MOSFETs and with IGBTs.
Quick Answer
Pulse-width modulation is produced by a firing circuit built from an inverter and a comparator, with a comparator square-wave generator and triggering circuits on the same board. The pulses drive either a MOSFET bridge or an IGBT bridge into a load resistor, so students can compare the two devices and watch output voltage change with modulation. Two +12 V DC supplies are built in, schematic diagrams are printed on the panel and test points bring out every node for measurement. It runs from 230 V AC ±10%, 50 Hz; a 20 MHz dual-trace oscilloscope is needed and not included. Please confirm the inverter DC bus voltage at quotation.
