If you are a technician or an electrician, you must have come across the term Buck-Boost transformer. A Buck-Boost transformer is a type of transformer that can be used for voltage regulation in power distribution systems. In this article, we will discuss the basics of Buck-Boost transformer wiring diagram.
What is a Buck-Boost Transformer?
A Buck-Boost Transformer is a type of transformer that can be used to raise or lower the voltage in an alternating current (AC) circuit. It is called a Buck-Boost transformer because it can both buck and boost the voltage depending on the power requirements of the system. Buck transformers are used to decrease voltage while boost transformers are used to increase voltage. A Buck-Boost transformer is capable of doing both.
It is commonly used for voltage regulation in single-phase and three-phase power distribution systems. A Buck-Boost transformer can be used to raise or lower voltage by up to 20% of the input voltage.
How Does a Buck-Boost Transformer Work?
A Buck-Boost transformer has two windings, the primary and the secondary. The primary winding is connected to the input power source, while the secondary winding is connected to the load. These two windings are not electrically isolated from each other, unlike in an isolation transformer. The voltage output on the secondary winding can be adjusted by changing the number of turns in the secondary winding compared to the primary winding.
A Buck-Boost transformer can be wired in two ways, as an auto transformer or as an isolation transformer. In the auto transformer wiring configuration, the primary winding and the secondary winding share a common wire or tap. In the isolation transformer wiring configuration, the primary winding and the secondary winding do not share a common wire or tap.
Buck-Boost Transformer Wiring Diagram
The wiring diagram of a Buck-Boost transformer is straightforward. It consists of the primary and secondary windings, and the tap connections. The tap connections are used to adjust the output voltage of the transformer.
The primary winding is connected to the input power source, while the secondary winding is connected to the load. The connection between the primary and secondary winding can be made in two ways. In the auto transformer configuration, the primary and secondary winding share a common wire or tap. In the isolation transformer configuration, the primary and secondary winding do not share a common wire or tap.
The Buck-Boost transformer wiring diagram can be illustrated as follows:
