Description
Technical field
The utility model relates to the direct current output module, the continuous adjustable alternating current-direct current dual output reserve arrangement of particularly a kind of photovoltaic inverse switch power supply.
Background technology
Along with the develop rapidly of electronic technology, increasing electric equipment products enter into huge numbers of families, are dissolved into the dribs and drabs in our life.We are to the demand of electricity, the dependence of electricity is also become become clear day by day.Pendulum is that a lot of electric equipments all must use 220V alternating current or small voltage direct current in the difficult problem in face of us at present; And transmission cable is inconvenient to move; And not covering of national grid in certain areas; So in some limitation that becomes in the face of wire cable when using removable electrical equipment, make and just can't use modern electric equipment products, make people can't enjoy the facility that modernized electric equipment products are brought at all in many places.Therefore, people press for a kind of power supply and can use in the place of setting up cable, can not cover or some beta sites uses at some cable again; The alternating current of 220V can be exported, the small voltage direct current can be exported again.
The photovoltaic inverter has satisfied the demand of people to a certain extent, and still, present photovoltaic inverter output model is single, or is the alternating current of only exporting 220V, or only exports 3V, 4.5V, 6V, is the direct current of 12V to the maximum.But along with advancing by leaps and bounds of science and technology; Increasing direct current small voltage electronic product gets into our visual field; The specified input voltage that a lot of import electrical equipment require is not the normal voltage 220V of China, and the desired rated voltage of different DC electronic products is also inequality simultaneously, has plenty of 5V; Have plenty of 12V, have plenty of 24V or the like.
The utility model content
The purpose of the utility model is to provide a kind of continuous adjustable alternating current-direct current dual output reserve arrangement of photovoltaic inverse switch power supply of realizing supplied by AC/DC electricity.
The purpose of the utility model realizes through following approach: the continuous adjustable alternating current-direct current dual output reserve arrangement of a kind of photovoltaic inverse switch power supply; This module divides two-way to connect storage battery by solar recharging module, commercial power charged module, and storage battery connects AC output module and the direct current output module constitutes; Described AC output module is the inverter power circuit of output 220V alternating current, and described direct current output module is the adjustable transforming circuit of output DC.
Further; Described direct current output module is made up of parallel two-way circuit; One the tunnel be by rectifier bridge connect with the L296 chip, its periphery is connected some resistance again and parallelly connected some electric capacity constitutes, another road is by rectifier bridge parallel connection filter capacitor, connects L79M05 voltage stabilizing chip again and constitutes.
Further, described inverter power circuit adopts the TL494C chip.
Further, described storage battery is 12V.
Further, the direct current of adjustable transforming circuit output is 3-30V.
Further, storage battery connects AC output module and direct current output module through relay.
The continuous adjustable alternating current-direct current dual output reserve arrangement of a kind of photovoltaic inverse switch of the utility model power supply, it charges through solar energy or the civil power accumulator jar to 12V, when needs use, outwards exports electric energy by the 12V accumulator jar then.Through reverse transformation is that the alternating current of 220V or the alternating current of other type are that current consuming apparatus provides electric energy; Externally export the continuously adjustable direct current of 3V～30V simultaneously.Send into single-chip microcomputer after using A/D converter that cell voltage is gathered during this time, show cell voltage through the LCD LCDs then; Through external matrix keyboard the output dc voltage size is preset or revises simultaneously; Then the result being sent into the VD that single-chip microcomputer and A/D converter collection return compares; Algorithm through the single-chip microcomputer internal composition produces control signal adjustment direct voltage output valve by D/A converter, makes it to match with the matrix keyboard input value.By the LCD LCDs direct voltage output valve is shown simultaneously.
The continuous adjustable alternating current-direct current dual output reserve arrangement of a kind of photovoltaic inverse switch of the utility model power supply; Its volume is little, is convenient to move, carry, as long as there is being light that convenient can the use lastingly in ground of heat arranged; No matter be or in the open air, can both well electric energy output be provided for the user in special emergent occasion.Compared with prior art, it also has following two key characters: 1. the alternating current of both exportable 220V or other type on same power supply, and exportable again continuously adjustable direct current, its range of application is wide.2. supply voltage output regulative mode is through the corresponding numeral input of matrix keyboard, and simultaneously with the whether success of checking button that pipes of buzzer, and auxiliary to show that with LCD display it presets, changes voltage convenient, easy to operate, is prone to promote suitable all kinds of crowds' uses.
