SEMINAR ON BUCK-BOOST TRANSFORMER
[attachment=42605]
INTRODUCTION
Buck boost transformers are single phase KVA, 600V insulating transformers with dual primary and dual secondary windings.
Buck boost transformers are effectively utilized as a cost effective method of correcting and lowering (buck) or making higher (boost) voltages and the voltage corrections.
Buck boost transformers are a standard type of single phase distribution transformers that utilizes primary voltages of 120,240 or 480 volts and secondary voltages of 12,16,24,32 or 48 volts which are commonly available in sizes ranging from 50VA-10kVA.
A buck–boost transformer is a type of autotransformer used to make adjustments to the voltage applied to alternating current equipment.
The buck–boost transformers are less costly than a two winding transformer as the buck–boost winding must only carry a fraction of the load power than two windings carry full power delivered to the load for large adjustments in voltage.
Types Of Buck Boost Transformer
There are two basic types:-
self-adjusting (active) transformers
Passive transformers.
The active types monitor incoming voltages and will adjust the outgoing voltage to be within an acceptable range.
The system will either buck (lower) or boost (raise) the voltage if it senses a variance in the incoming voltage.
In an active buck–boost transformer, a control circuit which selects tap to use to maintain the output voltage within the desired range.
Passive transformers are used for larger equipment where the amount of buck or boost is fixed.
The passive transformers are rated in volt-amperes and are rated for a percent of voltage drop or rise.
