Diodes

Semiconductor devices that allow current to flow in one direction only, used in various electrical applications.

3-Phase

Refers to an electric power system that uses three alternating currents of the same frequency, which are out of phase with each other by 120 degrees, to deliver power in a more efficient manner than single-phase electricity.

Full-Rectification

The conversion of AC (alternating current) to DC (direct current) using both halves of the input waveform, usually in power supply or electronic signal processing.

Rotor
