Computer PSU
DC Laptop Computer PSU Circuit Operate your laptop from a car can be done easily if you have a DC to DC Converter, namely a power supply device for changing a DC voltage into another DC voltage is greater (step-up) or smaller (step-down). Changes in output voltage is usually followed by changes that accompany the current. This Step-up DC-DC converter [...]
Switching Power Supply
40A Switching Power Supply Circuit Here is a switching power supply circuit specifically designed to power a ham station. This switching power supply produces 13.8V regulated on a continuous load current up to 40A. Very precise connected directly to a 12V battery backup because it has a current-limiting. If the potentiometer is rotated, while in a state regulated, switching power [...]
