Embodiment Construction

[0049] The power converter of the present invention will be fully understood through the description of the following embodiments, so that those skilled in the art can implement it accordingly. However, the embodiments of the present invention are not limited by the following examples.

[0050] In view of the shortcomings of the existing power converters that use switching methods to change the output voltage and the power converters that include multiple keys (keys) with an electronic component inside to determine the output voltage, the present invention develops an appearance as shown in Figure 2 ( a) to (c) show the first preferred embodiment of the power converter 10 . The power converter is a single-input converter, that is, it can only accept DC power input or AC power input. As shown in Figure 2 (a) to (c), the power converter 10 of the present invention includes a main body component 11, an input terminal 112, a first connection port 113, a power cord 12, which inclu...

Abstract

Making a input voltage convert to a output voltage, the disclosed power supply change over device includes following parts: a main component of having a case; a input end; a conversion circuit connected to the input end electrically; multiple resistors connected to the conversion circuit and the first connection port; and a switch over unit. The switchover unit includes a switch over head in use for the conversion circuit to generate the output voltage in a specific value. The switchover head includes an input connection port and an output connection port. The input connection port through theswitchover unit is connected to the first connection port so that each resistor is connected to ground or in open circuit or connected to output voltage. The output connection port is connected to the input connection port electrically in order to output the voltage.

Description

technical field [0001] The invention relates to a power converter, especially a power converter capable of providing multiple output voltages through an adapter. Background technique [0002] In addition to the use of batteries, any electronic equipment must rely on the supply of external power. Therefore, how to convert different forms of power (whether it is DC or AC) into a fixed form and range of power required by electronic equipment , is of course a very important subject. [0003] The power converter is a device to achieve such a mission. In general, power converters can be divided into DC-DC, AC-DC and other conversion methods according to the type of transfer, so that users can make appropriate conversions according to different needs. choose. [0004] Generally speaking, the purpose of the power converter is to adapt to the existing but not required voltage, and convert it into the required voltage form and size, so that the electronic equipment can be used smoo...
