What does the term commutation refer to in electrical systems?

The term commutation in electrical systems specifically relates to the process of converting alternating current (AC) to direct current (DC). This conversion is fundamental in various applications, especially in power supplies and motor control systems, where DC is often needed for sensitive electronic devices or for feeding into battery systems.

During commutation, the current changes direction, and the circuitry must ensure that transitions are smooth to avoid generating unwanted electrical noise or spikes that could disrupt the operation of connected devices. In the context of electric motors, effective commutation is vital for maintaining torque and reliability.

Understanding commutation is crucial in the design and operation of circuits and devices where maintaining a steady flow of current is necessary, hence underscoring the importance of this concept in electrical engineering.
