Description
Technical field
The present invention relates to a kind of power source aging device, especially relate to a kind of power source aging system.
Background technology
The ageing test of electronic product is the necessary means of controlling Quality of electronic products, getting rid of electronic product early failure hidden danger.Power supply is as the part of electronic product or electronic product, and the stability of itself directly affects the stability of electronic product work, and front needs carry out strict burn-in test therefore power supply dispatches from the factory.General power source aging system is next aging as its power termination with cement resistor or other pure resistive module at present, and electric energy is wasted by power termination in the process of power source aging like this, and this utmost point does not meet the policy requirements of energy-conserving and environment-protective.And select design along with the variation of the model specification of power supply need to re-start the power termination of power source aging system, its flexibility, versatility are relatively poor.Compare with the conventional power source aging equipment, the charged ageing system of power supply of the present invention is exactly a kind of energy saver of developing for the huge waste problem that solves the energy in the pure resistive ageing process of power supply.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of power source aging system, solved the expensive problem that the conventional power source aging equipment causes a large amount of waste of energy.
To achieve these goals, the technical solution used in the present invention is:
A kind of power source aging system, civil power is input to the mains hybrid inverter by static switch K, and the output of mains hybrid inverter is connected to the input that is aging power supply U, and the output that is aging power supply U is connected to the mains hybrid inverter by diode D.
The quantity that is aging power supply U is a plurality of, is arranged in parallel, and the quantity of corresponding diode D is also a plurality of.
Static switch k is controlled by logical circuit.
Mains hybrid inverter A is responsible for that electric current collects, direct current is to the conversion that exchanges and the modulation of phase place, the electric energy in circuit is reclaimed and power from the suitable electric energy of city's electric absorption.
The charged ageing system of this cover power supply uses ohmic load in present power source aging loop, and the conventional apparatus of a large amount of electric energy of waste has proposed to use inverter to replace the improvement of resistance as load.The mains hybrid inverter will be aging the converting direct-current power into alternating-current power of power supply output, and this alternating current has been realized the recycling of electric energy through can be used as the input in power source aging loop after phase-modulation.Owing to being that a plurality of Switching Power Supplies are simultaneously aging in the reality use, so the present invention has improved the utilance of electric energy greatly, reduced the power source aging cost.
Description of drawings
Accompanying drawing is structural representation of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further details.
As shown in drawings, the present invention is a kind of power source aging system, a kind of power source aging system, civil power is input to the mains hybrid inverter by static switch K, the output of mains hybrid inverter is connected to the input that is aging power supply U, and the output that is aging power supply U is connected to the mains hybrid inverter by diode D.The quantity that is aging power supply U is a plurality of (U1-Un), is arranged in parallel, and the quantity of corresponding diode D is also a plurality of (D1-Dn).
Static switch is responsible for the switch of whole system and is controlled; Diode has the unidirectional general character, can prevent from that each road is aging to produce the damage power supply of playing a reversed role between the output current of power supply, and each electronic component in power source aging system is shielded; The civil power inverter is as the load of Switching Power Supply, and the direct current with multiple power supplies output pools together simultaneously, and the direct current that receives is become the alternating current consistent with the civil power phase place through modulating transformation, provides electric energy as the electric supply installation that is aging power supply for it.If this part electric energy can not satisfy the demand that is aging power supply, then draw electric energy from civil power and replenished.The present invention has realized the recycling of electric energy, thereby has greatly improved the utilance of electric energy, has effectively solved a large amount of waste problems of conventional power source aging equipment to electric energy, has reduced the power source aging cost.
Usually in use, at first closed static switch when aging work is carried out, civil power is introduced aging loop, alternating current is by being aging output DC after power supply, the mains hybrid inverter receives the direct current of each power supply output, becomes the alternating current consistent with the civil power phase place through modulating transformation, re-enters the power source aging loop as the power supply of power supply, if this part electric energy can not satisfy the demand of Switching Power Supply, then draw electric energy from civil power and replenished.For utilizing the unidirectional general character of diode to prevent playing a reversed role of electric current for the pressure drop difference that is aging power supply, with the electronic component in this protective circuit.
The course of work of the present invention is: control static switch by logical circuit closed, the input civil power.At first the alternating current of input introduces mains hybrid inverter A, mains hybrid inverter A provides alternating current for power supply U1-Un, subsequently, the 220V alternating current becomes low-voltage DC (such as 6V, 12V, 24V etc.) output after power supply through being aging, if each road is aging the pressure drop difference that power supply U produces, each road output may be played a reversed role by generation current.Utilize the one-way conduction characteristic of diode K can prevent that electric current from playing a reversed role, the electronic device in protective circuit.Be aging the direct current of power supply output through the mains hybrid inverter, the mains hybrid inverter collects electric current and the direct current modulation conversion of input is become go forward side by side line phase modulation of alternating current, make this alternating current phases consistent with the civil power phase place in input power aging loop, at last the alternating current of output is re-entered the power source aging loop.
The above; only embodiments of the invention; be not that the present invention is imposed any restrictions, every any simple modification, change and equivalent structure of above embodiment being done according to the technology of the present invention essence changes, and all still belongs in the protection range of technical solution of the present invention.
