I have been put forth with this question many times in this blog, how do we add a changeover selector switch for automatically toggling of an inverter when AC mains is present and vice versa. And also the system must enable automatic switching of the battery charger such that when AC mains is present the […]

2 Automatic Heatsink Temperature Controller Circuit
In this post we study about a automatic fan speed regulator circuit for controlling the temperature of a heatsink and from preventing the temperature to reach dangerous levels. This approach is to ensure safeguarding of the connected devices wit the heatsink. Written by: Preeti Das With the help of this circuit the speed of a […]
10 Automatic Emergency Light Circuit Diagrams Explain
In this article I have explained 10 simple automatic emergency light circuits using high bright LEDs. This circuit can be used during power failures and outdoors where any other source of power might be unavailable. What’s an Emergency Lamp An emergency light is a circuit which automatically switches ON a battery operated lamp as soon […]
Automatic Door Controller Circuit Diagram using a Single Push-Button
This door controller circuit works in this way: Initially the door is in the closed state. When a push button is pressed, the door begins opening until it reaches the end of the course. When it reaches the end, it automatically reverses its direction and now the door begins closing. It keeps moving until it […]
Automatic Voltage Stabilizer Circuit for TV sets and Refrigerator
Here we will study the design of a simple automatic mains AC voltage stabilizer which can be applied for safeguarding appliances like TV and refrigerators from fluctuating voltages. A voltage stabilizer is a device which is designed to sense inappropriate voltage fluctuations in AC mains supply inputs, and correct them to produce a stabilized voltage for the […]
Automatic Inverter Output Voltage Correction Circuit
The common problem with many low cost inverters is their incapability of adjusting the output voltage with respect to the load conditions. With such inverters the output voltage tends to increase with lower loads and falls with increasing loads. The circuit ideas explained here can be added to any ordinary inverter for compensating and regulating […]
