Voltage converting equipment

Abstract

The invention provides voltage converting equipment, comprising input interfaces which are connected with a power adapter of a computer, an inductive resistor which is used for inducting output voltage signals of the power adapter, a plurality of power switches of the power adapter which are used for setting rated power of the power adapter, a comparator which is used for comparing received voltage values with voltage values corresponding to the selected rated power and outputting control signals in accordance with the comparison result, a first control switch which is switched off when the power adapter is in an underloading state and switched on when the power adapter is in a full load state, an electric pressure converter which is used for converting the received voltage, output interfaces which are used for providing a voltage output by the power adapter for the computer, and a plurality of output ports which are used for providing a voltage output by the electric pressure converter for correspondingly connected electronic equipment. The voltage converting equipment is used for providing a working voltage for a notebook computer and providing different voltage output interfaces to meet different voltage demands.

Description

technical field [0001] The invention relates to a voltage conversion device, in particular to a voltage conversion device connected between a notebook computer power adapter and the notebook computer.
