True or False: The main difference between a boost and buck transformer connection is the reversal of the series winding connections.

The statement is true because a boost transformer and a buck transformer are indeed differentiated primarily by the way their windings are connected. In a boost transformer configuration, the series winding connections are arranged in such a manner that they add voltage to the source voltage, effectively increasing the output voltage. This is achieved by connecting the primary winding and the secondary winding in a specific orientation that reinforces the voltages.

Conversely, in a buck transformer configuration, the windings are connected in such a way that the output voltage is reduced compared to the input voltage. The reverse arrangement—where the secondary voltage opposes the primary voltage—results in a lower voltage output.

Thus, the main distinction lies in the reversal of the series winding connections, which fundamentally alters the function of the transformer from boosting voltage to bucking it. Understanding this connection behavior is crucial for linemen when they are setting up or troubleshooting these types of transformers in power systems.
