Abstract
The invented microcomputer built-in uninterrupted switch power supply consists of master switch. The characteristic lies in that the master switch is connected on the accumulator. There are ac and dc voltages in the input circuit and exchange circuit. The pulse wide modulation I serves for the action to ac output, the pulse wide modulation II serves for action while inversion. It possesses of the functions of on-line power on and off, protection and warning and features high efficient, energy saving and safety.
Description
The present invention relates to a kind of is built-in uninterruped switch power supply, and it unites two into one traditional separate power supply and pc switching mode power supply.
Existing computer power all is to adopt Switching Power Supply, export four groups of DC voltage, do not possess uninterrupted function, when having a power failure for really reporting, computer data is not lost, necessary external uninterrupted power source, usually Switching Power Supply and uninterrupted power source all are series connection, and the uninterrupted power source volume is big, cost height, shortcoming such as efficient is low.
The present invention is directed to above-mentioned shortcoming, propose a kind of microcomputer built-in uninterruped switch power supply, promptly the online uninterrupted power source of collection in the microminiature volume and the Switching Power Supply two big functions of microcomputer inside are the novel power supply of one, and microminiature, low cost, high-quality are arranged.
Task of the present invention is finished like this, master switch is connected on the accumulator, when switch opens, among input circuit and the translation circuit I AC and DC voltage is arranged also, it is that output is worked to direct current that pulsewidth is transferred to I, it is that output is worked to direct current that pulsewidth is transferred to I, and pulsewidth is transferred to when control II is inversion and is worked.
The present invention has following effect: microcomputer built-in uninterruped switch power supply is specially designed at China's power supply grid environment; the voltage scope of application extremely wide (0～250V); has online power failure power supply; protection and warning function; efficiently, energy-conservation, safety; be replace traditional separate type Switching Power Supply and uninterrupted power source desirable integrated, the novel computer power of microminiature.
Accompanying drawing 1 is a The general frame of the present invention
Describe embodiment in detail in conjunction with above accompanying drawing, the input anti-jamming circuit, its effect is the extraneous high frequency interference that suppresses to come from electrical network, to guarantee that computing machine is not influenced by it, the high frequency interference that power supply itself is produced suppresses simultaneously, in order to avoid pollute electrical network.By rectifying and wave-filtering I, again by pulse width modulation controlled I, reach the purpose of voltage stabilizing, by translation circuit I and translation circuit II, it can realize the automatic conversion of two groups of power supplys, makes output voltage not have break time fully.Again by rectified wave filter II, pulse width modulation controlled II circuit, this control circuit for pulse-width modulation can be exported 181 ° of two pairs of phase phasic differences and have the driving pulse of time-delay through dc output circuit.Again through inverter circuit and holding circuit, this power-supply device+5V overvoltage protection ,-5V, 12V overcurrent protection, output overloading protection; battery under-voltage protection is through charging circuit, through battery cave voltage; play metering function, analyse slowdown monitoring circuit by warning circuit and input voltage at last and all finish and realize.
