Description

A kind of regulated power capacitor

Technical field

The utility model relates to a kind of power supply, especially a kind of regulated power capacitor.

Background technology

Stabilized voltage power supply is to provide the electronic installation of stablizing AC power or DC power supply for load.Comprise alternating current steady voltage plug and the large class of D.C. regulated power supply two.Alternating current steady voltage plug claims again AC voltage regulator.Along with the development of electronic technology, particularly electronic computer technology are applied to after each industry, scientific research field, the ac power supply that various electronic equipments all will be aspired for stability, the direct power supply of electrical network can not be satisfied the demand, and the appearance of stabilized voltage power supply has solved this problem.

And on Intelligent integration power condenser product, need the stable DC30V in a road, and the power supply of 1A, this power supply is, by transformation, 400V is become to 31V through over commutation and filtering, and voltage is in DC40V left and right, and after integrated circuit voltage stabilizing, voltage stabilizing is to 30V.The input voltage of this integrated circuit reaches as high as 50V.Through under on-the-spot actual motion, find that integrated circuit there will be the situation of damage.Through investigation, reach a conclusion, the load factor of a lot of newly-built engineering transformers is lower, and the floating voltage of power transformer is higher, and in the time of high, 0.4KV line voltage can reach 460V.After Intelligent integration power condenser inner pressure relief transformer again after rectifying and wave-filtering, the voltage being added on integrated circuit reaches 55V left and right, cause the critical value of this device operating voltage, cause in use procedure device fault rate higher, this is that what to adopt due to stabilized voltage power supply is that such problem has just appearred in voltage reducing type voltage stabilizing circuit.

Summary of the invention

The purpose of this utility model is, a kind of regulated power capacitor of voltage stabilization is provided.

The utility model solves the technical scheme that its technical problem adopts: a kind of regulated power capacitor, comprise power capacitor, current rectifying and wave filtering circuit, stabilized voltage power supply, power capacitor is connected with current rectifying and wave filtering circuit, current rectifying and wave filtering circuit is connected with stabilized voltage power supply, and described stabilized voltage power supply is boost type stabilized voltage power supply.

Of the present utility modelly further be set to: stabilized voltage power supply comprises MC33063 chip, MC33063 chip has DRC, Ipk, VCC, CII, SWC, SWE, TC, eight interfaces of GND, DRC is contact resistance R029 successively, inductance L 03, Ipk, after Ipk contact resistance R028, be connected with VCC, VCC connects polar capacitor C08, ground connection after the parallel circuits that capacitor C 07 forms, SWE and GND ground connection, TC connects the rear ground connection of capacitor C 09, CII, between SWC, connect successively voltage stabilizing didoe D17 and resistance R 030, polar capacitor C11, capacitor C 10, the parallel circuits that resistance R 032 forms, one end is connected with diode D17, the other end is connected with resistance R 031, resistance R 031 respectively with resistance R 030, polar capacitor C08, the parallel circuits that capacitor C 07 forms connects.

Said structure adopts MC33063 boost type voltage stabilizing circuit, and input maximum input voltage is 12VDC～40VDC, and output 1.5A, replaces original voltage reducing type voltage stabilizing circuit.The inner step-down transformer of Intelligent integration power condenser becomes 16V by 400V, obtains 20V direct voltage after rectifying and wave-filtering, obtains 30V direct voltage after MC33063 boosts voltage stabilizing.If the output appreciation 19.2V of the inner step-down transformer of Intelligent integration power condenser during 0.4KV line voltage appreciation 480V like this obtains the direct voltage of 26V left and right after current rectifying and wave filtering circuit, be less than the maximum input voltage of MC33063.Still can stablize normal work.After actual motion checking adopts this chip, the voltage stabilizing circuit at this place is always very stable, no longer outlet fault.
