Background technology
Along with the development of power technology and lighting technology, power supply product quantity in people's life is more and more, and importance is also more and more higher.For guarantee that power quality can long-time steady operation, power supply and lighting apparatus production firm need carry out 24 or 48 hours non-stop run burn-in tests to power supply, just can be applied in the product through the qualified product in test back.The power source aging process is except power supply is inserted the electrical network, also to connect to power supply and go up load, make power supply to be fallen but these electric energy all become thermal energy consumption usually in DC power output under the rated power, these transform the part that consumes is a huge waste to enterprise.The wasting of resources problem that the utility model produces at consuming a large amount of electric energy in the power source aging process, a kind of power supply feedback power supply energy-saving device is proposed, power supply in burn-in test output electric energy can be carried out conversion, make its interchange input of supply power again, thereby improve the utilance of the electric energy in the power source aging process.
Summary of the invention
The purpose of this utility model is to solve power-supply device to consume a large amount of electric energy in the production ageing process, brings huge energy expenditure to enterprise, proposes the energy saver of a kind of power supply output feedback power supply.
The energy saver of a kind of power supply output feedback power supply that the utility model proposes mainly comprises following components: DC load analog module, charging energy-storage module, frequency conversion inversion module, AC exchange conversion switching controls module, transition detection module, dsp processor control module.
The energy saver of a kind of power supply output feedback power supply that the utility model proposes is with the bulk supply of 220VAC alternating current as whole device, this device can according to the specified input of power supply to be aging set two kinds of 220V/50Hz and 100V/60Hz different exchange output mode, to give aging power supply power supply.The dc output end of aging power supply is linked into the input of the DC load analog module of this device, according to load voltage value and the current value of aging power supply the equivalent load of the fictitious load of device is set adjustment, feasible aging power supply operate as normal.The DC load analog module cooperates the charging energy-storage module, and the direct current of the output of aging power supply is stored in the energy storage super capacitor.Whether the dsp processor control module can reach the set point that possibility of reversal is exported by the electric energy that the transition detection module detects in the energy storage capacitor; When reaching possibility of reversal feedback power supply state, dsp processor control frequency conversion inversion module converts the direct current energy in the energy storage capacitor to the output AC of setting, and control AC exchange conversion switching controls module, start the feedback powering mode, device is exchanged the output be outputted to variable frequency inverter, import as the alternating current of aging power supply with the alternating current of the electric energy conversion of using aging power supply direct current output.
The energy saver of a kind of power supply output feedback power supply that the utility model proposes, make that by the above technology originally consuming useless electric energy in the power source aging process is re-used, thereby can provide the utilance of the electric energy in the power source aging process, for enterprise saves a large amount of electricity charge, and be that society saves a large amount of energy.
