Abstract

The modular converter of dc voltage includes following parts: a unit of detecting voltage is in use for detecting an input voltage, and a detected voltage is outputted if the input voltage exceeds the first voltage; based on input voltages, first and second voltage conversion units carry out voltage conversion, and output a first, second, third, and fourth output voltages to a host board; if the first and second voltage conversion units receive a detecting signal, then an input voltage is converted to first, second, third, and fourth output voltages; if not, then the input voltage is as the first output voltage, and the input voltage is converted to second, third, and fourth output voltages; when receiving a starting signal, a main control unit of power supply causes first, second voltage conversion units to carry out voltage conversion, and when first, second, third, and fourth output voltages are ready, a signal of power good is output to host board.

Description

technical field [0001] The invention relates to a direct current (DC) voltage conversion technology, in particular to a direct current-direct current conversion structure. Background technique [0002] In general, DC-DC voltage converters are used in many industries, including power supplies for computers, personal digital assistants (PDAs), mobile phones, and other hand-held mobile electronic devices and systems, and in every Each product has a specific need. [0003] However, DC-DC converters used in traditional computer systems can only accept a fixed level of input voltage (such as 12V) without high-voltage input protection, and their output power is too low to meet higher power requirements. demand. Contents of the invention [0004] In view of this, the primary purpose of the present invention is to provide a voltage conversion module that can receive a predetermined range of input voltage, has high voltage input protection, and has high output power. [0005] In ...
