Power Supply Circuits

DC to DC converter is good circuit. It can make voltage up or down for many use. In this article we will talk about 12V to 24V DC Voltage Converter Circuit using IC LM324 This circuit is a double input voltage using boost converter and oscillator. Load current must not be more than 800mA. The […]

Digitally Controlled Adjustable Voltage Regulator Circuit is made to give change output voltage for different use. IC LM317 popular regulator and give output 1.25V to 37V adjustable. In this circuit LM317 IC work with digital control transistors and let user choose voltage easy. It is good for different voltage need like microcontroller, power supply and […]

Voltage regulators important in electronic system as it keep voltage steady if input or load changes. IC LM317 is famous and it give 1.25V to 37V output by choosing resistors. This is Simple Adjustable Power Supply Circuit with IC LM317 Circuit show how it work, how to build and formula for design. Circuit Working: Parts […]

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. It changes three phase AC voltage to steady DC output which is good for motor, power supply and other uses. IC 20L6P45 like three phase diode bridge rectifier is […]

DC-DC Inverting Converter Circuit for 15V Output is of special type of circuit which changes positive voltage to negative voltage. This circuit is useful for things which need negative power like op-amps, analog and communication devices. The circuit uses uA78S40 IC and a switching regulator. It takes +15V DC in and give -15V out and […]

Switching Regulator are small circuit and easy to underderstand. They take little energy pieces from input and send it to output step by step. They turn power transistor ON and OFF fast and this controls voltage good. Different from linear regulators they do not waste energy as heat. They use parts like inductors, capacitors, diodes […]
