Power converter with variable output voltage

输出电压可变的电源转换器

Abstract

一种电源转换器,包括切换式电源转换单元及多个连接头。电源转换单元将外部电源转换成直流电压通过第一及第二输出端输出。电源转换单元包括第一及第二电阻器,第一电阻器两端分别耦接第一及第三输出端,第二电阻器两端分别耦接第二及第三输出端。电源转换单元根据第三输出端上的电压调整直流电压。每个连接头都具有第一至第三输入端、第四及第五输出端且都包括第三及/或第四电阻器,第一及第二输入端分别耦接第四及第五输出端,第三电阻器两端分别耦接第二及第三输入端,第四电阻器两端分别耦接第一及第三输入端。当不同的连接头耦接切换式电源转换单元时通过第四及第五输出端输出不同的输出电压。由此可避免人为误触,提高电源供给稳定性。
A power converter comprises a switchover-type power supply conversion unit and a plurality of connectors. The switchover-type power supply conversion unit converts an external power supply into DC voltage which is output through a first output terminal and a second output terminal. The power supply conversion unit comprises a first resistor and a second resistor, wherein two terminals of the first resistor are respectively coupled with a first output terminal and a third output terminal; and two terminals of the second resistor are respectively coupled with a second output terminal and a third output terminal. The power supply conversion unit adjusts the DC voltage according to the voltage on the third output terminal; each connector is provided with a first input terminal, a second input terminal, a third input terminal, a fourth output terminal, a fifth output terminal, and a third and/or fourth resistor, the first and the second input terminals are respectively coupled with the fourth and the fifth output terminals; two terminals of the third resistor are respectively coupled with the second and the third input terminals; and two terminals of the fourth resistor are respectively coupled with the first and the third input terminals. When different connectors are coupled with the switchover-type power supply conversion unit, different output voltage is output through the fourth and the fifth output terminals. Therefore, accidental electric shock can be avoided, and the power supply stability can be improved.
