The proposed slow-start power supply circuit is specially designed for power amplifiers to ensure that the loudspeaker connected with the amplifier do not generate the loud and unwanted “thump” sound during power switch ON. This also implies that the power supply will safeguard or protect the loudspeaker from the sudden inrush current transient from the […]

Motorcycle Button Start Locking Circuit
In this post I have explained how to modify an existing button start system in motorcycles so that it’s disabled as soon as the engine has started and gained the required minimum amount of RPM. The idea was requested by Mr. Jordan Circuit Requirements I just discovered your splendid site/blog with focus on education about […]
Submersible Pump Start/Stop Circuit
In this post I have explained an automatic submersible pump start, stop circuit with dry run protection in order to implement an automatic ON/OFF switching of the motor in response to the high/low water levels of the overhead tank. Circuit Concept In one of the previous posts I have explained a similar concept which also […]
PWM Motor Soft Start Circuit to Prevent High Consumption during Power Switch ON
In this post I have explained an effective PWM motor soft start circuit which can be used for enabling heavy motors with a soft start and thus prevent the equipment from drawing dangerous high currents. Why a Soft Start High wattage motors such pump motors or other forms of heavy industrial motors tend to draw […]
Oil Burner Button Start Ignition Circuit
In this post I have explained a simple automatic ignition for an oil burner system system which is initiated with a push button operation. The idea was requested by Mr. Andreas. Technical Specifications I have a request and i wonder if its possible for someone to find a simple circuit about oil burner controller. I’m […]
Refrigerator Motor Soft Start Circuit
Refrigerators tend to draw appreciable amounts of current each time their compressor switch ON, and this could happen many times per day. A soft start circuit to the compressor motor could probably tackle this issue and help save electricity. The idea was requested by Mr. Naeem Khan. Technical Specifications I need your help regarding to […]
