RPM Controller Circuit for Diesel Generators
In this post I have explained a diesel generator RPM controller circuit for boats using PWM technique and also using a simple triac shunt circuit. The idea was requested by […]
Triac Phase Control using PWM Time Proportional
A triac phase control using a PWM circuit can be useful only if it’s implemented using a time-proportional format, otherwise the response could be haphazard and inefficient. In a few […]
How to Make a Zero Crossing Detector Circuit
Making a zero crossing detector circuit is actually very easy and it could be effectively applied for protecting sensitive electronic equipment against mains switch ON surges. A zero crossing detector […]
