Understanding the Basics: Variable DC Power Sources Demystified

A variable DC power source, also known as a programmable DC power supply, is an electrical device that generates a controllable DC voltage or current. It consists of a transformer, rectifier, filter, and voltage regulator. The transformer steps up or down the AC voltage from the mains, while the rectifier converts the AC voltage to DC. The filter removes any AC ripple from the DC output, and the voltage regulator provides a stable output voltage.

The key feature of a variable DC power source is its ability to adjust both voltage and current output. This is achieved by using a control circuit that monitors the output voltage and current and adjusts the duty cycle of the PWM signal applied to the power MOSFETs. By varying the duty cycle, the output voltage and current can be precisely controlled.
