Abstract
The utility model relates to a power technology, in particular to an AC and DC power conversion device. The utility model aims to overcome the single power supply of the existing household electrical appliances and provide an AC and DC power conversion device in order to meet the need of dual power supply. The utility model adopts the technic proposal of the AC and DC power conversion device to solve the technic problem, characterized in that: the device includes a DC input port, an AC input port, a switching power, a switch and a DC-DC converter; the DC input port is connected with the switch and the AC input port is connected with the switch through the switching power; and the switch is connected with the DC-DC converter. The beneficial effects of the utility model are simple circuit structure, low cost and applicable to AC and DC power supply.
Description
Technical field
The utility model relates to power technology, particularly the supplied by AC/DC electricity conversion equipment.
Background technology
At present, household appliances have become requisite thing in our daily life, and its supply power voltage generally is civilian alternating current.In some less-developed places and the relatively more nervous place of the energy, its use just is restricted.
The utility model content
Technical problem to be solved in the utility model is exactly at the existing single shortcoming of household appliances supply power mode, provides a kind of supplied by AC/DC electricity device, to adapt to dual power supply.
The utility model solve the technical problem, and the technical scheme of employing is that the supplied by AC/DC electricity device is characterized in that: comprise the direct-flow input end mouth, ac input end mouth, Switching Power Supply, diverter switch and DC-DC converter; Described direct-flow input end mouth is connected with described diverter switch, and described ac input end mouth is connected with described diverter switch by described Switching Power Supply, and described diverter switch is connected with described DC-DC converter.
The beneficial effects of the utility model are that circuit structure is simple, and is with low cost, is suitable for two kinds of power supplys of alternating current-direct current.
Description of drawings
Fig. 1 is a structured flowchart of the present utility model;
Fig. 2 is the schematic diagram of embodiment.
Embodiment
Below in conjunction with drawings and Examples, describe the technical solution of the utility model in detail.
The utility model utilizes diverter switch that the input power supply is switched, and in mode cheaply, has realized the dual power supply of power consumption equipment.
The technical solution of the utility model is that the supplied by AC/DC electricity device comprises the direct-flow input end mouth, ac input end mouth, Switching Power Supply, diverter switch and DC-DC converter; Described direct-flow input end mouth is connected with described diverter switch, and described ac input end mouth is connected with described diverter switch by described Switching Power Supply, and described diverter switch is connected with described DC-DC converter;
Concrete is that described diverter switch is made of relay; Described relay normally open contact is connected with Switching Power Supply, and described relay normally-closed contact is connected with the direct-flow input end mouth, and described relay control end is connected with Switching Power Supply, and described relay output end is connected with described DC-DC converter;
Perhaps, described diverter switch is a Manual Transfer Switch;
Further be that described DC-DC converter output voltage is greater than 2 groups.
As shown in Figure 1, the direct current of direct-flow input end mouth input is connected to diverter switch; The alternating current of ac input end mouth input is changed by Switching Power Supply, and the direct current of Switching Power Supply output is connected to diverter switch equally.Diverter switch adopts Manual Transfer Switch, and as push-button switch, toggle switch etc., the user can be by manually selected input voltage kind; If adopt the diverter switch of control automatically, then can realize automatic control.The direct current of diverter switch output is through the required direct voltage of DC-DC converter output.
Embodiment
As Fig. 2, this routine diverter switch adopts relay.The normally-closed contact of relay is connected with the direct-flow input end mouth, and relay normally open contact is connected with Switching Power Supply, and relay control end (drive coil) is connected with Switching Power Supply.In Switching Power Supply inside, alternating current (220V) obtains being approximately the direct current of 300V through behind the rectifying and wave-filtering, adjusts conversion through PWM, last output dc voltage.Because the relay drive coil is connected with one tunnel VD of Switching Power Supply, when Switching Power Supply was worked, relay normally open contact was connected, and whether no matter there is direct current to press input, the DC-DC converter all is operated in and exchanges under the input pattern.When ac input end does not have input, or turn-off after the alternating current, the relay normally-closed contact is connected, and the DC-DC converter is operated under the direct current input pattern.The output voltage of DC-DC converter is designed to the output of many group voltage, can provide suitable power supply for power consumption equipment, as the capable power supply of 130V of television set, 24V field ionization source and 12V working power etc.The diverter switch that this is routine does not need complicated control circuit, has realized the automatic switchover of power supply.The technical solution of the utility model, the power supply that is particularly suitable for household electrical appliance designs.
