Commutation in Electrical Engineering: A Comprehensive Guide

Commutation is a fundamental concept in electrical engineering that plays a crucial role in the operation of various devices and systems. It refers to the process of reversing the direction of current flow in a circuit, typically achieved by switching the connections of a device to an external power supply.

What is a commutator?

Simply put, the commutator turns the coils on and off to control which direction the electromagnetic fields are pointing. On one side of the coil, the electricity should always flow "away," and on the other side, electricity should always flow "towards.". This ensures that the torque is always produced in the same direction.

OverviewConnection of two power elementsThe structure of a commutation cellThe commutation cell in convertersSee alsoExternal links

The commutation cell is the basic structure in power electronics. It is composed of two electronic switches (today, a high-power semiconductor, not a mechanical switch). It was traditionally referred to as a chopper, but since switching power supplies became a major form of power conversion, this new term has become more popular. The purpose of the commutation cell is to "chop" DC power into square wave alternating current. …

Definition for self-commutated switches

Self-commutated switches (GTO, IGBT, MOSFET) Bi-directional switches (SSWI) Switch models are ideal. That is, both turn-on and turn-off transients are neglected. A switch has an on-resistance of 10µΩ and an off-resistance of 1MΩ. Snubber circuits are not required for switches. Here is the only definition that I found: Self-Commutated Switches.

Commutator

Group theory. The commutator of two elements, g and h, of a group G, is the element. [g, h] = g−1h−1gh. This element is equal to the group''s identity if and only if g and h commute (that is, if and only if gh = hg ). The set of all commutators of a group is not in general closed under the group operation, but the subgroup of G generated by ...

What Is The Function Of The Brushes And Commutators In An Electric …

The function of the commutator is twofold. First, it acts as a mechanical switch, continuously reversing the direction of current flow in the armature winding as the rotor rotates. This reversal is necessary because the magnetic field generated by the stator''s electromagnets changes in polarity as the rotor spins.
