This 10A power supply circuit s based on the ISL8200M IC which require few external components and is very easy to build but is capable to offer a high power making it useful in current-sharing DC DC power supply module for those power hungry Datacom\Telecom\Servers.
A 12 to 220 volts voltage converter electronic project can be designed using electronic diagram below. This 12 to 220 volts voltage converter electronic project is designed using CMOS 4047 integrated circuit, that converts a voltage of 12 volts DC into a 220 volt alternative. CMOS circuit 4047 is used as a multivibrator. From the output pins, pins 10 and 11 a symmetrical square wave is amplified by Darlington transistors T1 and T2, which ultimately reach the transformer secondary coil.
With the potentiometer P1 output frequency can be adjusted within certain limits (50-400Hz).
A transformerless power supply electronic project can be design using electronic diagram below. This transformerless power supply allows to power a device that requires a voltage of 12 volts, without using a transformer . Using this power supply can be powered a consumer requiring a maximum current of 10 mA.
