Description
Technical field
This utility model is related to computer power supply technical field, specially a kind of anticreep computer with warning function
Power supply.
Background technology
Computer belongs to light current product, that is to say, that the running voltage of part than relatively low, typically within positive and negative 12 volts, and
And be unidirectional current.And common civil power is 220 volts（Some countries are 110 volts）Alternating current, it is impossible to directly on machine element
Use.Therefore computer needs a power pack as a lot of household electrical appliances, and being responsible for for common civil power being converted to computer can be with
The voltage for using, is typically mounted at computer-internal.The core component running voltage of computer is very low, and due to computer
Operating frequency is very high, and therefore the requirement to power supply is higher.The power supply of computer is on-off circuit at present, by common alternating current
Switch to unidirectional current, then by chop control voltage, different voltage is exported respectively and gives the computer such as mainboard, hard disk, CD-ROM drive portion
Part.
The reason for computer power supply produces electric leakage is mainly power supply casing and is not separated with insulant with computer cabinet
Open, therefore leakage current can be delivered to computer host box, will get an electric shock when user is using computer, affect to calculate
The life safety of machine user, this are accomplished by a kind of computer power supply can when computer leaks electricity with warning function, remind
User is noted in use.
