Digital 5V Power Supply using L296
This circuit is derived from an application note of L296, It is a Power Switching Regulator from ST. The advantage of using a switching regulator is that there is not much Heat Dissipation in...
5V -1A Power Supply using LM2575
A Power Transistor which is having a drop of 4 Volts across it and passing 3 amps thru it, may dissipate around 12 Watts of Heat, This is the problem in Series Regulators. While...
Battery Management and Supply Design
As you have have pointed out, my circuit is not driving any motor or such loads…but it is driving a Wireless Module which draws about 165mA to 240mA from my circuit during transmission [for...
Three Phase AC SSR for 1 HP Motor
I need to build a three phase AC(in 120V)-AC(out 440V) solid state relay to turn on or off a small(1hp) three phase AC motor. Do you have any idea? Can I use three MOC3043...
Pulse width modulation using 555
IC1 astable gives a fixed square wave at pin 3, C1 and R1 derive uS trigger pulses from IC1 and this will trigger IC2 monostable or single shot, the voltage at pin 5 of...
Mains Voltage Indicator with a LED
This is a mains 230V AC voltage indicator and is a LIVE CIRCUIT, so take care. The Resistor has to be a fusible ceramic wire wound and the capacitor 630V AC or higher capacity....
Mains Current Indicator with a LED
This is a mains 230V AC load current indicator and is a LIVE CIRCUIT, so take care. The Resistors have to be a fusible ceramic wire wound. More at Mains Voltage and Power Circuits...
