Answer :
Final answer:
A buck-boost transformer is not ideal for fluctuating loads because voltage drop on a line can vary significantly with the load. They have limitations, especially under highly variable conditions and may not maintain high efficiency when load changes rapidly.
Explanation:
A buck-boost transformer is not an optimal choice for use with a fluctuating load because the voltage drop on a line varies with load. Buck-boost transformers are designed to handle specific voltage conversions, but they are not ideal for loads that change rapidly over time. A fluctuating load demands a rapid response to maintain voltage levels, which can be a challenge for these transformers. While they can handle variations to some degree, buck-boost transformers may struggle with efficiency under highly variable conditions.
It's also important to remember that transformers, in general, have limitations. For example, transformers do not work for pure DC voltage input, and there are factors like efficiency to consider. While transformer efficiency often exceeds 99%, assuming negligible resistance, this may not hold as true under fluctuating loads where maintaining efficiency can be more challenging.
