significant industry attention today is the application of digital technology to power supply control. This topic attempts to clarify some of the mysteries of digital control for the practicing analog power supply designer. The benefits, limitations, and performance of the digital control concept will be reviewed.

2024年11月4日 · The unit digital power supply circuit provides a variable, fluctuation-free and regulated ten different DC power supplies. These are 1.5V, 3V, 4.5V, 5V, 6V, 7.5V, 9V, 10.5V, 12V positive power supply, and 12V negative power supply.

Define the ADC signal conditioning circuits. Choose the configuration of the timing hardware that implements the PWM signals, ADC strobe and interrupt service routine (ISR) timing.

What is Digital Power Supply? • “Digital Power Supply” is a power system that is controlled by digital circuits, in much the same way as would be with analog circuits, to monitor, supervise, communicate and control looping. • A fully digital controlled power system includes both “Digital Control” and “Digital Power Management”

2019年7月24日 · We will discuss all scaling factors in detail with worked examples to show how to account for them. We will also discuss how to calculate and overcome the phase loss in a digital power supply. Finally we will carry out a detailed step-by-step design example for a real power supply and present real experimental results to verify the theory.

The UCD3138 is a fully programmable digital power supply controller offering superior levels of integration and performance in a single chip solution. The flexible nature makes it suitable for a wide variety of power conversion applications, include power factor correction (PFC), LLC resonant converter, phase shifted full bridge, etc. In

Figures 1 and 2 show the simplest rectifier circuits. In these basic configurations the peak voltage across the load is equal to the peak value of the AC voltage supplied by the transformer’s secondary winding. For most applications the output ripple pro- duced by these circuits is too high.

Variable Power Supply with Digital Control. A variable power supply circuit is built with variable positive voltage regulator LM317, CMOS decade counter IC CD4017, timer IC NE555 and fixed negative voltage regulator LM7912. The AC supply is fed to the transformer which is stepped down to 12V AC.

2017年5月25日 · Here we present a variable power supply with digital control that is simple and easy to construct. The circuit is built around an adjustable 3-terminal positive-voltage regulator IC LM317, CMOS decade counter IC CD4017, timer IC NE555 and 3-terminal fixed negative-voltage regulator LM7912.

This Power Supply has a digital volt & ampere meter which receives its power from a 15 Volt voltage regulator (IC1). This 15 Volt is also used as input for the 5 Volt voltage regulator (IC5) that powers the PIC and the digital potentiometer.
