Make this 220V to 12V SMPS Using UC2842 IC
This UC2842 IC based SMPS design is simple, cheap and efficient kind of isolated power supply. We can use it in off-line stuff like AC-DC adapters, battery chargers and all those small power supplies. What is cool? It takes that high voltage AC then steps it down and then keeps input and output fully isolated […]
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 […]
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 […]
DC to DC Converter Circuits using SG3524 [Buck, Boost Designs]
A DC to DC converter is basically a switch-mode power supply, designed to work either as a boost-converter to step-up a low voltage DC to a higher voltage DC, or as a buck-converter to step-down a higher voltage DC to a lower voltage DC. The switched mode conversion ensures that the power transfer in the […]
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 […]
