| A cycloconverter oftenly called as 'cycleconverter' changes the frequency of a single(or three phase ) alternating power sourcewithout the necessity of an intermediate ac todc conversion stage. A cycloconverter requiremultiple control device of a single or threephase excitation, and are limited to low outputfrequency only. The output of a cycloconverterhas a relatively large ripple voltages butcomparatively small ripple currents, which iswhat contributes to motor heating. |
| This unit is given to study of single phase dualconverter operation. It has inbuilt step downtransformers for converters, step downtransformer for synchronization, currentlimiting reactor, two fully controlled bridgeconverters with output cut - off switches and asmall saparately excited dc motor as load. Theunit operates on 220Vac. A clear acrylic top isfitted to look the components. |

In ac circuits the phase controlled rectifier
can be turned on at any angle a with respect
to the applied voltage polarity. The angle a is
oftenly called the firing angle. These circuits
are characterized as controlled rectifiers or
converters. In present model study of such
controlled rectifier in bridge configuration is
performed. The prime aim of firing circuit to
produce trigger pulses to the thyristors at
different firing angles.
