Thyristor And Diode Converters

Product Description

Description: The Thyristor and Diode Trainer is a versatile teaching aid.It explores the principles and applications of thyristors, diodes andconverters. The control panel has clear mimic diagrams with shrouded sockets.Students use shrouded leads to connect the different parts of the circuits. Theparts include thyristors, diodes, inductors, transformers and smoothingcapacitors. A mix of standard analogue meters and a multifunction digital metermeasure the currents and voltages in the circuits. The multi-tappedtransformers give a choice of single and three-phase AC voltages for connectionto the diodes and thyristors. A centre-tapped inter phase transformer shows theeffect of reducing circulating currents in rectifier circuits. A load inductorshows the effect of inductance when smoothing the AC ripple in rectifiercircuits. Fast-blow fuses on the control panel protect the load side ofexperiment circuits. Students use controls on the lower panel to adjust ACsupply voltage and ballast resistance during experiments.Key Specifications: Six diodes Six thyristors Three multi-tapped transformers One interphase transformer Internal and external thyristor fi ring control Two resistive loads One inductive load Oscilloscope Key Features: Fully equipped for both single and three phase experiments Internal or external thyristor firing control source Selectable gate pulse monitor connection to compare firingpulse with output waveforms Variable thyristor firing delay for studies of harmonics andeffect of firing delay on output waveforms Transducers and oscilloscope included for waveformmonitoring
