Schematic Diagram Of Power Supply With Explanation. This schematic does not show the control circuitry that s why you see all mosfet gates and transistor bases are open. Usb 5v to 1 5v 3v dc adapter converts usb to 1 5v or 3v output small uninterruptible ups.
It is quite easy to understand the working process of the switching power supply. 24v 2a power supply circuit. The diagram below shows a partial schematic of a 450 watt atx power supply.
For clarity the parts responsible for miscellaneous auxiliary functions such as current limit fan control and ov protection which are not essential for learning the basic concepts of the power conversion are not shown as well.
In a linear power supply the power transistor is operated in a linear mode. 12v and 5v output many ideas of 12v and 5v dual power supply circuit diagram at 3a max. Some circuits would be illegal to operate in most countries and others are dangerous to construct and should not be attempted by the inexperienced. It helps us to design the sections of the circuit individually and then at the end put them together to have a complete circuit ready for use.
