The post presents a couple of simple LED intensity controller circuit which may be appropriately configured for specific related applications. The idea was requested by Mr. Chand. Technical Specifications I would like to have a circuit designed by you which is very simple and straightforward. This will be incorporated as a stand alone feature in […]

Higher Variable Output Voltage from IC 7812
You may have often wondered whether it was feasible to get higher voltages than 12 V from a 7812 IC? In this short post I have explained how to configure the IC 7812 with a BJT stage, so that its output can be made variable for achieving any desired voltage higher than 12 V, without […]
LM317 Variable Switch Mode Power Supply (SMPS)
So far in this website we have studied LM317 based linear power supply circuits, here I have explained how an LM317 can be executed as a variable switch mode power or SMPS with zero loss. LM317 as Linear Regulator We all know that an LM317 IC is internally designed to work as a linear voltage […]
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 […]
Single Phase Variable Frequency Drive VFD Circuit
In this post I have explained a single phase variable frequency drive circuit or a VFD circuit for controlling AC motor sped without affecting their operational specifications. What is a VFD Motors and other similar inductive loads specifically do not “like” operating with frequencies that might be not within their manufacturing specs, and tend to […]
100 amp Variable Voltage Power Supply Circuit Diagram
The post describes a simple but extremely versatile 100 amp, variable voltage power supply circuit using just a few BJTs in parallel and in a common collector mode. The idea was requested by Mr. Andre. Technical Specifications Hello Swagatam, I was wondering if you could possibly assist me. on the blogs I have seen some […]
