Product Code : SCL-EELE-12476
Indian Lab Suppliers supplies the Power Electronics Lab (Product ID: 12476) as part of its electronics engineering lab equipment range. It is a power electronics lab unit with on-board supplies, triggering and firing circuits, SCRs and other power devices for 32 characteristic, triggering, commutation, rectifier, chopper and inverter experiments.
Quick Answer
Device experiments cover V-I and gate characteristics of the SCR, UJT (with interbase resistance and intrinsic stand-off ratio), MOSFET, IGBT, DIAC, TRIAC and PUT. Triggering and conversion work includes R and RC triggering, SCR triggering by UJT, 555 and IC 741 circuits, ramp-and-pedestal triggering of anti-parallel SCRs, class B, C, D and F commutation, a voltage-commutated chopper, the Bedford inverter, MOSFET and IGBT single-phase PWM inverters, and half-wave, mid-point and fully controlled bridge rectifiers with R and RL loads. The triggering circuit gives five gate outputs (40-900 Hz, 12 V, PWM on G1-G4 with 0-100% duty), the rectifier firing angle is variable from 0° to 180°, and a four-output isolated firing circuit with pulse transformers drives the four 2 A SCRs; please confirm the SCR voltage rating at quotation. Supplies reach ±35 V DC and 18-0-18 V AC, and the 5 W load resistors get hot, so switch off before rewiring.
