Abstract
The invention provides a UPS and a control method thereof. A rectifier converts commercial power into DC power for detection by a control processor, when detecting that voltage is higher than set voltage, the control processor controls a first switch to be switched on, power is supplied by direct use of the commercial power, and at the same time, a part of the commercial power is distributed to a charger to charge a battery; and when detecting that the voltage is smaller the set voltage, the control processor controls the first switch to be switched off, and an inverter inverses the voltage of the battery into AC commercial power voltage for output. According to the invention, the inverter is at a work state only when the battery works, such that the power consumption can be reduced, and the life is prolonged. Besides, AC output and DC voltage output are independently controlled, such that power can be supplied to different devices.

A kind of control method of ups power, wherein, ups power comprises control processor, rectifier, inverter, charger, battery, first switch, civil power is converted to direct current and detects to described control processor by described rectifier, when the voltage that described control processor detects closes higher than controlling described first switch during setting voltage, direct use mains-supplied, a part for civil power is assigned on described charger to described battery charging simultaneously, when the voltage that described control processor detects is less than the voltage of setting, described control processor controls described first switch and disconnects, the voltage inversion of described battery is that the line voltage exchanged exports by described inverter, use the described mains-supplied that inversion comes.
Further, wherein said inverse converter adopts metal-oxide-semiconductor.
Further, wherein when directly using mains-supplied, provided direct voltage output by the described battery charged,
Further, wherein said direct voltage is the USB interface output of 5V.
Further, wherein provide power supply to described control processor by described battery.
By ups power circuit provided by the present invention and corresponding control method, inverter only normally works when powered battery, and be in standby under other states, power consumption is little, and the life-span is long.In addition, in ups power of the present invention, civil power output and direct voltage output can control separately, can support all electronic product chargings.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, in describing embodiment below, the required accompanying drawing used is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, to those skilled in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the control circuit block diagram of the ups power of the embodiment of the present invention.
Embodiment
Illustrate clearly and completely the technical scheme in the embodiment of the present invention below in conjunction with drawings and Examples, described embodiment is only the present invention's part embodiment, but not as the foundation limited the present invention.Do not making based on those skilled in the art's those of ordinary skill the every other embodiment obtained under creative work prerequisite, all belonging to the category of the present invention's protection.
Fig. 1 shows the control circuit block diagram in the ups power of the embodiment of the present invention.Control circuit in Fig. 1 in this ups power comprises, rectifier 1, charger 2, control processor (under be called for short CPU) 3, inverter 4, battery 5, some K switch 1, K2, K3, interlock circuit 6, specifically, when there being civil power, rectifier 1 converts civil power to direct current and detects to CPU3, when control processor is called for short CPU detection voltage for 3 times higher than setting voltage, control switch K1 closes, direct use mains-supplied, and by control switch K2, control the output of line voltage, a part for civil power is assigned on charger 2, charger 2 charges to battery 5, battery 5 provides power supply to CPU3 in addition, now battery 5 can provide the direct voltage output of 5V, is controlled the output of direct voltage by K switch 3.In one embodiment, be export with USB interface form.Civil power in the embodiment of the present invention exports and direct voltage output can control separately, can support all electronic product chargings.
When exporting with normal line voltage, the inverter 4 in ups power is in holding state, can reduce its loss like this, strengthens the life-span.
When CPU3 detects that voltage is less than the voltage of setting, the power inverter of battery 5 is the voltage of civil power and is converted to alternating current output by its control inverter 4, and inverter 4 is in running order; By control switch K2, the interchange controlling the line voltage be converted to exports; Use the described mains-supplied that inversion comes.While inverter 4 starts conversion, CPU3 control switch K1 disconnects, and the function of the realization that inverter 4 is main is boosted and be converted into alternating current by battery 5 direct current out.
In a specific embodiment, what inverter 4 adopted is metal-oxide-semiconductor, and its advantage is, the time interval of conversion is short, there will not be the situation of power-off, successfully manages emergency.
