Abstract
A kind of battery feed circuit, comprises external-connected port, battery supply end and earth terminal, is connected in series the first electric capacity between described external-connected port with battery supply end, described external-connected port be connected in series the second electric capacity between earth terminal.The utility model by increasing by two electric capacity on the external-connected port of original battery feed circuit, a ground connection, one connects power end, and the electric capacity increased by two can the effectively interference that sealed in by external-connected port of filtering external circuits, the increase stability of a system.
Description
Technical field
The utility model relates to a kind of battery feed circuit.
Background technology
When charged autonomous system product produce in batches time will with extraneous communication data, but when communication interface is set up (signal wiring), outer welding system can cause interference the product of charged autonomous system cannot normally be worked.
Summary of the invention
The utility model provides and a kind ofly filtering can seal in the battery feed circuit that interference, cost are low, increase the stability of a system.
The technical solution adopted in the utility model is:
A kind of battery feed circuit, is characterized in that: comprise external-connected port, battery supply end and earth terminal, be connected in series the first electric capacity between described external-connected port with battery supply end, described external-connected port be connected in series the second electric capacity between earth terminal.The utility model by increasing by two electric capacity on the external-connected port of original battery feed circuit, a ground connection, one connects power end, and the electric capacity increased by two can the effectively interference that sealed in by external-connected port of filtering external circuits, the increase stability of a system.
The beneficial effects of the utility model: can filtering seal in interference, cost low, increase the stability of a system.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with specific embodiment, the utility model is further described, but the utility model is not confined to these embodiments.One skilled in the art would recognize that the utility model covers all alternatives, improvement project and the equivalents that may comprise in Claims scope.
With reference to Fig. 1, a kind of battery feed circuit, comprises external-connected port 1, battery supply end 2 and earth terminal 3, described external-connected port 1 be connected in series the first electric capacity C1 between battery supply end 2, described external-connected port 1 be connected in series the second electric capacity C2 between earth terminal 3.The utility model by increasing by two electric capacity on the external-connected port 1 of original battery feed circuit, a ground connection, one connects power end, and the electric capacity increased by two can the effectively interference that sealed in by external-connected port 4 of filtering external circuits 4, the increase stability of a system.Battery feed circuit in the utility model is more existing power supply circuits.
When the external-connected port 1 of battery feed circuit connects external circuits 4, the interference that external circuits 4 seals in divides following two kinds:
When high voltage interference, the second electric capacity C1 plays a role and the voltage exceeded is sponged by capacitor charging.
When low-voltage is disturbed, the second electric capacity C2 first plays a role, and the second electric capacity C2 discharges; If drop-out voltage is larger, the electricity that second electric capacity C2 deposits cannot eliminate the interference of ground voltage completely, so only the second electric capacity C2 is inadequate, after adding the first electric capacity C1, time local voltage disturbance is come, the second electric capacity C2 discharges, now the first electric capacity C1 also discharges, and the first electric capacity C1 can supplement electricity by power supply, enhances the effect of filtering low-voltage interference.
