EMI Shielding Techniques and Concepts

EMI is the hardest thing to deal in switching power supply design. There are several factors that worsen EMI and there are also some ways to minimize EMI and able to pass the standards. One of the several ways to combat EMI is through shielding and we will discuss here EMI shielding techniques. Before going far, let us define EMI.

Snubber 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

SURGE PROTECTION CIRCUIT PRINCIPLE and DESIGN

Surge protection circuit is the one referred by many as protector for voltage spikes in AC grid lines; however it is not limited particularly in AC grid lines. Surge protector or surge protection device is a device that will provide surge suppression or voltage spike suppression so that sensitive devices will not get damage. Surge protector can handle voltage spikes

NPN Transistor applications and uses

NPN Transistor Principles and Practical Uses

Basic NPN Transistor Principles Universities are covering this topic very well but despite I still attempt to discuss NPN transistor principles that I think easier to understand for non technical people. NPN transistor is the name given to a bipolar junction transistor with two N type materials or negative carriers while there is only one P type material or positive

Transformer Model in LTSpice – Step by Step Guide

I love LTSpice due to its very easy interface and very handy. It has several built-in models that can be used. For ICs, it has many parts available to be used in simulation although most of it is manufactured by Linear Technology (the maker of LTSpice). For beginners and newbie to LTspice, I suggest you visit the tutorial LTSpice Circuit Simulation

Capacitor as ESD Protection

Electrostatic discharge or simply ESD is a universal problem in electronic circuits. Capacitor as ESD protection is providing economical solution to the problem. I used to work in automotive electronics and we used high frequency capacitors to protect the exposed pins of our product. Exposed pins are the one accessible to users. There are several ways to protect devices from

Switching 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
