Abstract
The invention provides a stack type power supply adapter comprising a plugging body and an adapter piece. The plugging body comprises a first plugging front end, a base level voltage generation unit, a first plugging tail end and a first output end. The first plugging front end is electrically connected with an AC power supply. The base level voltage generation unit generates reference voltage and outputs the reference voltage to the first plugging tail end and the first output end, wherein the reference voltage is U0. The adapter piece is plugged with the plugging body and comprises a second plugging front end, a timed level voltage generation unit, a second plugging tail end and a second output end. The second plugging front end is plugged with the first plugging tail end. The timed level voltage generation unit progressively increases the reference voltage at the timed level and then outputs the progressively-increased reference voltage to the second plugging tail end and the second output end. Output voltage of the second plugging tail end and the second output end is U1, and U1=2*U0. Size of the output voltage increases with the number of the inserted adapter pieces at the timed level so that adjustment of the size of the output voltage is facilitated for users.
