Description
Technical field
The utility model relates to a kind of supply unit, but relates in particular to the uninterrupted power supply of AC/DC, belongs to electricity field.
Background technology
To be alternating current be converted to direct current by the UPS rectifier to existing ups power charges a battery and exchange as the external equipment power supply by inverter, being converted to, and this ups power can not provide direct current to export.Along with the broad development of electronic equipment, occurred that many needs use galvanic equipment, at ups power in such cases, can not directly use, need extra AC/DC changeover switch, increased the trouble in the application.
Summary of the invention
For the needs of prior art, a kind of direct current and non-break power supply that exchanges output of providing is provided the utility model, can provide AC and DC two kinds of outputs, has applicability widely.
For achieving the above object, the utility model is achieved through the following technical solutions:
Direct current and the non-break power supply that exchanges output are provided, has pluggable direct current output module, described direct current output module comprises circuit board, circuit board is provided with and exchanges modular converter, DC conversion modules and output port, and the input of DC conversion modules, output are electrically connected to the output that exchanges modular converter and output port respectively; Base, have the tank that holds described circuit board, and base one end has the opening of corresponding circuits plate output port; Upper cover, for the hollow housing shape with base coupling and have under shed, the end face of upper cover has two parallel elongated slots, and elongated slot is respectively equipped with foldable power connecting sheet, and two power connecting sheets are electrically connected to the output of ups power.
By said structure, when needs used direct current, the output that the direct current output module is inserted into to ups power got final product output DC; When needs use alternating current, the direct current output module is pulled up and got final product.
Wherein, the pulse wave width modulation module that described interchange modular converter includes full-wave rectifier and is connected with full-wave rectifier, the input of full-wave rectifier is connected to two power connecting sheets, and the output of pulse wave width modulation module is connected to the input of DC conversion modules.
By using rectifier and pulse wave width modulation module (being PWM), the 220V alternating current of UPS output can be converted to the DC power supply of low-voltage.
Wherein, described DC conversion modules comprises DC-DC converter, and the input of DC-DC converter is connected to the output of pulse wave width modulation module, and the output of DC-DC converter is connected to output port.
By using DC-DC converter, namely the DC-DC transducer, convert the direct current of high pressure to low-voltage DC, as from 30V-5V etc., is suitable for small household appliances, uses such as mobile phone, Portable fan.
By above-mentioned improvement, non-break power supply of the present utility model is achieved AC and DC output, and the standby supply of electric power can be provided for the electrical equipment of number of different types.
The accompanying drawing explanation
Fig. 1 is non-break power supply structural representation of the present utility model.
Embodiment
Non-break power supply of the present utility model, on traditional ups power basis, increased the direct current output module, this direct current output module is connected with the delivery outlet of ups power body is separable by socket, described direct current output module comprises circuit board 20, base 30 and upper cover 40, base 30 is coated on circuit board 20 outsides with upper cover 40, and whole DC Module can become direct current by the alternating current of ups power output.
Wherein, circuit board 20 is provided with and exchanges modular converter 21, DC conversion modules 22 and output port 23, interchange modular converter 21, DC conversion modules 22 are positioned at circuit board one end, output port 23 is positioned at the other end, the input of DC conversion modules is connected to the output that exchanges modular converter, and the output of DC conversion modules is connected to output port 23.
Wherein, base 30 position in the central has opening 31 upwards, can put into circuit board 20, at the one end, has the opening corresponding with the output port of circuit board 32.
Wherein, upper cover 40 is complementary with base 30, and the end face of upper cover 40 has two parallel elongated slots 41, the interior power connecting sheet 42 that collapsible withdrawal is installed of each elongated slot, these two power connecting sheets can insert the output of ups power, thereby the 220V alternating current of UPS output is introduced to the direct current output module.Power connecting sheet with exchange modular converter 21 and be electrically connected to.When not needing to use, from ups power, pull up folding to get final product in elongated slot 41 the direct current output module.
When non-break power supply of the present utility model uses, by power connecting sheet, from ups power, obtain alternating current (voltage is 90-240V usually), process full-wave rectifier and PWM are converted to the direct current (normally 30V) of low voltage.To those skilled in the art, rectifier, PWM are conventional electronic units, can buy from the market finished product, and it will not go into details herein.DC conversion modules, namely common described DC-DC transducer, can be converted to low voltage and direct current than the direct current of high voltage, commonly 30V-12V conversion, 30V-5V conversion, thereby to common small domestic appliance power supply.To those skilled in the art, the DC-DC transducer is also common electronic component, can buy from the market.
