Figure 1: Schematic diagram of the universal AC-DC power supply circuit, 12V-3A (36W) AC1 and AC2 are AC input Nets corresponding to two Pads on the PCB for Mains connection. R2 is a varistor (MOV), ...

In this installment of Circuit VR, we’ll look at a simple buck converter — that is a switching regulator that takes a higher voltage and produces a lower voltage.

The capacitor auto-discharge module presented in this article is simply a failsafe module that automatically discharges the buffer/filter capacitor in a power supply circuit when its input supply is ...

We’ve all seen those cheap bench power supply units (PSUs) for sale online, promising specifications that would cost at least a hundred dollars or more if it were a name brand model. Just how… ...

Circuit diagrams were designed using LTSpice and Ansys SIWave Simulation software and thermal, direct current (DC) and frequency analyses were performed. Efficiency and output voltage fluctuations ...

High-end, custom capabilities Monitoring and control completely independent of operator touch screen Generator control completely independent from master controller ...

This paper presents a variety of traditional switching power supply auxiliary start circuits, and analyzes the characteristics and the defects of these circuits. On this basis, then proposes revised a ...

The high-efficiency switching power supply has become a staple ingredient in many of today’s electronic systems. What are its origins and how has it evolved over the decades?

Wall-wart power supplies are everywhere in modern life. These Chanzon 12V 2A UL-listed 24-watt AC/DC switching power supply adaptors are available on Amazon. You might not give much thought to what’s ...

In addition to the schematic export, CAD models for select Power Integrations components can also be downloaded on the main SnapMagic Search website, previously known as SnapEDA.
