Apr 14, 2019 · Commutation in Power Electronics refers to the process of commutation of SCR. Whenever we talk of commutation in power electronics, we simply mean the process to turn off an SCR. This article details about the commutation of SCR, Natural Commutation, Forced Commutation and various types of Forced Commutation techniques.
So, commutation is how we do that. In brief, this is how we manipulate currents in inductors to build magnetic fields in motors to ‘pull’ the motor-rotor around. Properly ‘commutating’ a motor means properly aligning this magnetic field to produce maximal torque.
Thyristor commutation is a process used in power electronics to Turn OFF a thyristor (also known as a silicon-controlled rectifier or SCR) after it has been turned on. Once a thyristor is triggered into conduction, it will remain in the conducting state until the current flowing through it drops below a certain level (known as the holding ...
Power Electronics refers to the process of controlling the flow of current and voltage and converting it to a form that is suitable for user loads. The most desirable power electronic system is one whose efficiency and reliability is 100%. Take a look at the following block diagram.
Commutation cell. 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.

A PCs power supply is an example of a piece of power electronics, whether inside or outside of the cabinet. Power electronics is the application of electronics to the control and conversion of electric power . The first high-power electronic devices were made using mercury-arc valves. In modern systems, the conversion is performed with ...
