How to Build a Boost Converter Circuit: Explained with Calculations
I have explained comprehensively how to build a boost converter circuit for converting a low level DC voltage inputs to a higher level DC voltage outputs. I have furnished all the required calculations s that you can design a customized boost converter circuit. A Practical Boost Converter Circuit Design using IC 555 This simple circuit […]
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 […]
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 […]
110 V to 310 V Converter Circuit
The discussed circuit is a solid state AC to DC voltage converter that will convert any AC input between 85 V and 250 V into a constant 310 V DC output. This kind of circuits are normally use in LCD TV sets for operating the system through inputs from 100 V AC to 250 AC. […]
The Role of Inductor Coil in SMPS
The most crucial element of a switched mode converter or an SMPS is the inductor. Energy is stored in the form of a magnetic field in the core material of the inductor during the brief ON period (ton) switched through the connected switching element such as MOSFET or a BJT. How the Inductor Works in […]
