Energy Storage | Applications | Capacitor Guide

Capacitors used for energy storage. Capacitors are devices which store electrical energy in the form of electrical charge accumulated on their plates. When a capacitor is connected to a power source, it accumulates energy which can be released when the capacitor is disconnected from the charging source, and in this respect they are similar to batteries.

Reduction of torque ripple in an electrolytic capacitor-less BLDC motor

One of the techniques proposed to remove the capacitor of the drive of a BLDC motor is the use of matrix converters, which uses a greater number of switches to deliver the AC power directly to the motor without any energy storage elements (inductor or capacitor) [7]. A second technique proposed is changing the structure of the drive.
