Abstract
There is provided a power supply for AC/DC and DC/DC conversion which receives the DC power supplied from airplanes, vehicles and vessels as well as normal AC power, and converts the power to DC power and supplies it to portable electronic products. The power supply for AC/DC and DC/DC conversion includes an AC input, a DC input, a switchfor selecting AC input power or DC input power, a DC output, and a circuit used for AC/DC and DC/DC conversionwhich converts the power input from the AC input or the DC input to DC power having predetermined values of current and voltage, and a secondary side of a transformer (TL) for AC/DC conversion inside the circuit for conversion serves as an inductor for performing DC/DC conversion. The power supply for AC/DC and DC/DC conversion is implemented in compact by providing an element capable of operating different functions upon AC/DC and DC/DC conversions respectively and decreasing the number of elements, thereby allowing an efficient and economical use of electric power and generating high power.
