In this post I will try to analyze what is constant current source and how it affects a load, or how it may be used with a load correctly for achieving the most efficient results. The following discussion between me and Mr. Girish will clearly explain what is CC or how constant current operates. How […]

Over Current Cut-off Power Supply Using Arduino
In this post I will show how to construct a battery eliminator / DC variable power supply which will automatically cut-off the supply, if the current flow through the load exceeds the preset threshold level. Main Technical Features The proposed over current cut-off power supply circuit using Arduino has 16 X 2 LCD display, which is […]
High Current Sensorless BLDC Motor Controller using Back EMF
In this post I have explained a high current sensorless BLDC motor controller circuit which does not depend on hall effect sensors for initiating the operations rather utilizes the back EMF from the motor for the sequential input Overview For proper commutation most 3-phase BLDC driver circuits rely either on a sensor based feedback or […]
High Current Motor Control Circuit using Arduino
In this project, I have explained how to control motor speed using Arduino PWM circuit, and how to implement reverse forward or direction control in a DC motor using Arduino through a couple of push button switches. Any high current motor upto 30 amp can be controlled using this set up. Introduction Motor is a […]
7 Watt LED Driver SMPS Circuit – Current Controlled
The presented 7 watt LED driver circuit is an SMPS based non-isolated, transformerless circuit which ensures a safe current controlled output for the attached LED, it is very affordable to build without involving complex transformer winding. Constant Current and Load Regulation Objective The aim behind the design of the IC TPS92310 (from TEXAS INSTRUMENTS) is […]
High Current Wireless Battery Charger Circuit
In this article I have explained regarding how to design and make your own customized high current wireless battery charger circuit using wireless power transfer concept. Introduction In many of my earlier articles I have comprehensively discussed wireless power transfer, in this article we will go a step ahead and try to learn how to […]
