Linear Power Supplies

Linear power supplies are rugged devices frequently used in industrial equipment, such as CNC machines, robots, and automated assembly lines. The basic components of a linear power supply are a transformer, a rectifier, and a filter capacitor:

The transformer steps down the input voltage to a lower voltage that is suitable for the rectifier
The rectifier converts the AC voltage to a DC voltage
The filter capacitor smooths out the DC voltage to remove any ripple

A regulated linear power supply also includes voltage regulation circuitry that maintains the output voltage at a constant level, regardless of changes in the input voltage or load current.

Regulated and unregulated linear power supplies offer several advantages, including low output ripple, high output voltage accuracy, and low output noise. They are relatively simple in design and generate minimal electromagnetic interference (EMI) due to the absence of high-frequency switching components.
