What is Voltage Regulator – Explained in Details
A linear voltage regulator is the easiest to deal with. It is very easy to create and do not need much technical knowledge to understand its behavior. It has two variations: series and shunt.
READBuck Converter Design Tutorial
Buck Converter Basic Function Before going to buck converter design tutorial, we will discuss first how buck converter works in order to fully understand the following tutorial. A buck converter is a switching converter with a voltage output lower than voltage input. It is also called as a step-down switching converter A buck converter has only four main parts. They
READSwitch Mode Power Supply Explained with Common Topologies
For small power applications like on board power sources, linear power supply is often used due to its simplicity and low cost. However, when the need for high power density designs arises, linear power supply simply disappears in the picture. It is because linear power supply is very less efficient. Switch mode power supply comes in place. Switch mode power
READSnubber Circuit Design Analysis
What is a Snubber? Snubber is a form of circuit protection against voltage spikes, ringing and oscillation effects. Snubber works by either clamping voltage spikes but not altering the ringing frequency or does the same function. Snubber Circuit Design is one of the complex tasks in circuit design. It needs a deep knowledge on circuit’s foundations to design a good
READACDC 5 Watts Charger Design Ready for Prototype
This article features a low parts count ACDC 5 Watts Charger Design with an output voltage of 5V and a maximum charge current of 1A. This is applicable for cell phones, tablets and other devices and gadgets that use 5 volt supply. This is a constant voltage constant current charger. A constant voltage means a steady level of the output
READSwitching Power Supply Operation Principle and Design
Switching power supply operation is very different to that of linear power supply. Despite of its complexity, higher bill of material cost and higher parts count, switch mode power supply is still the preferred power supply topology in the market nowadays. The main reason is higher efficiency and higher power density. Higher efficiency simply means that only a small portion
READSizing the Inductor of Buck Converter and Setting its Operation
One of the most important parts of a buck converter is the inductor. Sizing the inductor of buck converter and setting its operation mode makes the converter function correctly. The shape and the magnitude of current of the inductor are dictated by the inductance of the inductor itself. Therefore choosing the right inductor value is very important. Sizing the inductor
READBuck Converter Duty Cycle Derivation
In this article I will share to you the methods I used in buck converter duty cycle derivation. We will consider the ideal and the real scenarios. In ideal buck converter duty cycle derivation, you don’t need to consider the voltage drops of the switching element and catch diode. On the other hand, in real buck converter duty cycle derivation,
READHow Switch Mode Power Supply Regulates its Output
In linear power supply design output regulation is not a question because it is easily done by the linear regulator inserted before the load. Nowadays linear power supply is not anymore widely used. What is drawing more attention now is the switch mode power supply. How switch mode power supply regulates its output is different from what linear regulator does.
