Designing efficient power supply circuits have never been easy, however in the course of time researchers … Read morePower Factor Correction (PFC) Circuit – Tutorial
In this post we try to understand the method of dimensioning or calculating inductors in buck boost SMPS circuits in order to ensure an optimal performance from these devices. In a few of my earlier posts we comprehensively studied regarding how SMPS buck and boost converters work, and we also deduced a few fundamental formulas … Read moreCalculating Inductors in Buck Boost Converters
A boost converter (also called step-up converter) is a DC to DC converter circuit which is designed to convert an input DC voltage into an output DC voltage with a level that may be much higher than the input voltage level. However the process always conserves the relation P = I x V, which means … Read moreHow Boost Converters Work
In this post we learn how to select ferrite core material with the correct specifications for ensuring proper compatibility with a given SMPS circuit design Why Ferrite Core Ferrite is a wonderful core substance for transformers, inverters and inductors in the frequency spectrum 20 kHz to 3 MHz, owing to the benefits of reduced core … Read moreFerrite Core Material Selection Guide for SMPS
PWM stands for pulse width modulation which signifies the variable nature of the pulse widths that may be generated from a particular source such as a discrete IC, MCU, or a transistorized circuit. What’s PWM In simple terms a PWM process is nothing but switching ON and OFF a supply voltage at a particular rate … Read moreWhat’s PWM, How to Measure it
This power supply functions with a broad input voltage range from 90 to 265 V AC and produces a dual output in the form of 5 V / 2.5 A, and 14.5 V / 1 A. The Circuit Layout The great aspect of this source is its minimal power consumption, optimized power consumption in idle … Read moreLCD Monitor SMPS Circuit
