Simple High Power Three Phase Bridge Rectifier Circuit
Simple High Power Three Phase Bridge Rectifier Circuit is very important for factory and place where there is need of a big DC voltage and current. Also, it changes three phase AC voltage to steady DC output which is good for motor, power supply and other uses. The IC 20L6P45, which functions as a three-phase […]
Understanding Switching Regulator Circuit
Switching Regulator are small circuit and easy to understand, as they take little energy pieces from input and send it to output step by step; then they turn power transistor ON and OFF fast and this controls voltage good. Also, they are different from linear regulators as it do not waste energy as heat. In […]
Switching Regulator Circuit using IC uA78S40
The Switching Regulator Circuit using IC uA78S40 works as a buck converter that smartly and efficiently reduces a high input voltage to a lower output voltage. Also, IC uA78S40 chip is good for power supply and it has built-in parts like voltage reference that change with temperature, oscillator for duty cycle, strong switch, separate op-amp […]
Simple Time Delay Circuit for DC Power
Simple Time Delay Circuit for DC Power uses SCR and it is very useful in many uses and is easy to understand. Need wait before device ON? then this circuit gives delay after power ON; also circuit is good to turn devices one-by-one and avoid current spike. Also, the max input DC for this circuit […]
