Abstract
The utility model discloses an uninterrupted switch power supply module. In an internal circuit of the switch power supply module, after at least a large-capacity electrolytic capacitor is connected in series with a slow-recharging and quick-discharging circuit, which consists of a resistor and a rectifier diode in parallel connection, the capacitor is connected in parallel with a DC busbar inside the power source module. The uninterrupted switch power supply module has the advantages of the low cost, the simple and reliable technology, little influences on the original circuit, and so on.
Description
Technical field
The utility model relates to railway signal power supply system, a kind of specifically Uninterruptible Power Module.
Background technology
The power supply of the signal power source of railway output requires when alternating current input power supplying takes place 150MS with interior instantaneous interruption, and its power supply output power supply is uninterrupted.At present for reaching the purpose of uninterrupted power supply, use the power-supply device that contains battery, as uninterrupted power supply UPS etc., but this just needs to increase in addition charging device and battery, and the power-supply system volume is increased, and cost increases, and reliability reduces.
Summary of the invention
The purpose of this utility model is for providing a kind of cost low, the uninterrupted power supply that technology is simple and reliable.
The technical scheme that realizes the foregoing invention purpose is as follows:
A kind of uninterrupted switch power supply module has discharge the soon dc bus of Lu Houyu power module inside of at least one resistance of big capacity electrochemical capacitor series connection and the trickle charge of a whole utmost point pipe formation in parallel to be in parallel in the switch power module internal circuit.
Big capacity electrochemical capacitor capacity described in the utility model is greater than 470 microfarads.
Diode and resistance constitute charging battery circuit and fast discharge circuit in the utility model, make the increase of this partial circuit minimum to the overall performance influence of former power module, when exchanging the input normal power supply, by resistance storage capacitor is charged, the energy of storage capacitor is by diode D1 discharge when exchanging the instantaneous interruption of input, continue to keep the power supply of module, make the output power supply uninterrupted.It is low to the utlity model has cost, and technology is simple and reliable, and primary circuit is influenced advantages such as little.
