12 V to 30 V High Current Boost Converter Circuit [Variable]
In this post I have explained how to make a high current boost converter circuit which will step up a 12 V DC to any higher level up to 30 V maximum, and at an impressive 3 amp current rate. This high current output can be further enhanced by suitably upgrading the inductor wire gauge […]
How to Calculate Ferrite Core Transformers
Calculating ferrite transformer is a process in which engineers evaluate the various winding specifications, and core dimension of the transformer, using ferrite as the core material. This helps them to create a perfectly optimized transformer for a given application. The post presents a detailed explanation regarding how to calculate and design customized ferrite core transformers. […]
How to Design a Flyback Converter – Comprehensive Tutorial
A flyback configuration is the preferred topology in SMPS application designs mainly because it guarantees complete isolation of the output DC from the input mains AC. Other features include low manufacturing cost, simpler design and uncomplicated implementation. The low current DCM version of flyback converters which include output specification lower than 50 watt are more […]
