Answer :
Buck-boost transformers are typically available in sizes up to 10kVA.
Buck-boost transformers can be used as isolating transformers and are usually used to lower or raise line voltage. They are available in a range of sizes, ranging from 50 volt amperes to 360 kVA. Additionally, buck-boost transformers are in compliance with NEC and are typically used to buck (lower) or boost (raise) the supply voltage a small amount, usually 5 to 27%. Buck Boost Transformers can protect connected equipment from damage by reducing or raising line voltage 5% to 20%. Primary and secondary lead wires can be interconnected for use as an autotransformer. For use in induction motors and air conditioning, lighting, and heating systems.

Final answer:
Buck-boost transformers can have different sizes depending on the specific application and manufacturer. They are used to transform voltages from one value to another using induction in various electrical systems. The size availability can vary based on requirements.
Explanation:
Transformers are devices that transform voltages from one value to another using induction. They consist of two separated coils, or windings, wrapped around a soft iron core. The maximum size of buck-boost transformers typically depends on the application and the specific manufacturer.
For example, plug-in transformers that are commonly used for electronic devices operate in the 3 to 12 V range. Transformers used in power distribution systems can have voltages ranging from 5 to 13 kV for local distribution and up to 700 kV for long-distance transmission to limit energy losses.
The specific size availability of buck-boost transformers may vary based on the requirements of the application and the manufacturer.
