What process is called commutation in electrical systems?

Commutation in electrical systems refers specifically to the process of changing alternating current (AC) into direct current (DC). This is a crucial step in many electrical applications, especially in situations where DC is needed, such as in power supplies for electronics, electric motors, and charging systems.

The process often involves components such as diodes or thyristors that allow current to flow in one direction, effectively converting the alternating current, which periodically reverses direction, into a steady direct current. This conversion is essential for the operation of many devices that require a stable and constant voltage which DC provides.

The other choices, while closely related to electrical systems, do not accurately define commutation. Regulating voltage refers to maintaining a consistent output voltage level but does not involve the conversion between AC and DC. Storing energy in capacitors is a method used to manage voltage and energy, but it does not pertain to the commutation process itself. Transmitting power relates to the delivery of electrical energy from one point to another, which is also a different function within electrical systems.
