In this post I have explained a simple method of converting a wasted spark type ignition system in an automobile, into an enhanced, sequential spark, 6 cylinder engine type ignition system. The idea was requested by Mr. Brenton, as given below: Main Requirements I was looking through the car and motorcycle section but couldn’t find […]
High
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 […]
High Current Zener Diode Datasheet, Application Circuit
Zener diodes that are normally available are mostly 1/4 watt or 1/2 watt types. And it is quite valid since the basic function of zener is to create stabilized reference voltage. Zener diodes are not designed for current regulation directly. However, for some applications where shunting excess voltage and current is necessary a high current […]
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 […]
Mains High Low Voltage Protection Circuit with Delay Monitor
In this post I have explained an upgraded version of my previous mains 220V/120V high-low voltage cut off protection circuit which now includes a delayed restoration of power for the load with 3 LED power status indicators. The idea was requested by one of the dedicated members of this website. Circuit Objectives and Requirements Main […]
