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 […]
How to Interface Arduino PWM with any Inverter
In this post I have explained how to interface an existing Arduino PWM signal with any inverter to convert it into a sine wave equivalent inverter. The idea was requested by Mr. Raju Visshwanath Technical Specifications I am in need of following inverter circuit designs: Single phase DC to AC inverter. Input 230 VDC. PWM […]
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 […]
