Stabilizing 5V and 12V in a Computer Power Supply

In a computer power supply (PSU), the stabilization of 5V and 12V outputs is achieved using a switching power converter with feedback control. Below are the primary methods used for voltage stabilization:

1. PWM Control (Pulse Width Modulation)

Modern ATX power supplies use PWM to regulate the output voltage. A controller monitors the output voltage and adjusts the duty cycle of switching transistors accordingly. This maintains stable voltage levels despite changes in load.

What are convertors?

Presentation. The convertors in dc drive systems are designed to control and supply separately-excited dc machines in applications that demand rapid response, high accuracy and great reliability.

The convertors are available with single-convertor arrangement and in double-convertor arrangement.
