A **buck-boost transformer** gets its name from its ability to both **buck** (decrease) and **boost** (increase) voltage. Here's how it works:
- **Buck** means to **reduce the voltage**. In some situations, you may need to lower the voltage coming into a system to avoid damage to sensitive equipment or to meet the requirements of a particular device.
- **Boost** means to **increase the voltage**. In other cases, the incoming voltage might be too low to operate equipment properly, so the transformer increases it.
The buck-boost transformer is designed to handle small voltage adjustments (either up or down) and is often used to regulate voltage in a circuit. It's efficient because it's typically used when the voltage change needed is relatively small, unlike a regular transformer, which may be used for larger voltage changes.
In short, itβs called a **buck-boost** transformer because it can either lower (buck) or raise (boost) the voltage depending on the needs of the application.
