Over Voltage Protection for Automotive Load Dump
In this post I have explained an over voltage cut-off protection circuit in the form of automotive dump load for protecting sensitive and sophisticated modern automotive electronics from transient DC electrical spikes emanating in vehicle electrical. Transient bus voltages are a significant risk factor to integrated circuits. The maximum breakdown voltage that an integrated circuit […]
Solving Inverter “No Load Auto-Shutdown” Problem
In this post I have explained how to trick an inverter’s “no load auto-shutdown” feature through an external circuit so that the inverter may be kept running even with minor, below permissible loads at the output. The idea was requested by Mr. Em. Technical Specifications Thanks for your prompt responses and guidance. I was wondering […]
Grid Load Power Monitor Circuit for GTI
In this post I have explained a circuit idea which can be used as a power monitor and control system for ensuring that only the specified amount of watts is allowed to enter into the allocated socket, as per the maximum calculated wattage of the appliances connected across those points. The idea was requested by […]
No Load Detector and Cut-off Circuit for Inverters
In this post I have explained a relay cut-off circuit which may be included in inverters to ensures that under a no load at the output the condition is quickly detected and the supply cut off, preventing the inverter from operating unnecessarily. The idea was requested by Mr. Rajath. Technical Specifications I need to adopt […]
Lathe Machine Over Load Protector Circuit
In this article I have explained a simple overload cut off circuit for safeguarding heavy mains operated machines such as a lathe machine. The idea was requested by Mr. Howard Dean. Technical Specifications May I first say I have very little knowledge of electronics although I could follow a simple diagram. I operate a small […]
