Aging equipment described in the utility model can wear out to M * N power supply simultaneously, not only ageing efficiency is high, and take full advantage of the power of electronic load, make electronic load in the situation that fully loaded or approaching fully loaded work, like this under the condition that satisfies equivalent amount or equal capacity, the electronic load cost that drops into is original 1/N, has saved cost.For traditional electronic load or ohmic load, its aging electricity consumption only has 20% of traditional resistor load or electronic load, greatly reduces to produce to have reduced production cost.
In Fig. 1, the arrow aspect represents be energy flow to, power supply to be aging is divided into the M group, every group N, N equals the power of the single pass power of current-sharing module/single channel output small-power power, perhaps N also can obtain by following mode: namely N equals the output voltage of the current-sharing module single channel input voltage upper limit/single channel output small-power power, and the N value that two kinds of methods are calculated should equate; Behind N the single channel output small-power power process N passage series board, obtain a higher voltage, then be connected to an input channel of current-sharing module, the output corresponding to all input channels of current-sharing module is summarised in together, then be connected to the input end of main power inverting unit, finally by crossing main power inverting power back off is arrived electrical network, realize the recycling of electric energy.
Aging for single channel output small-power power, its pulling load current is lower, therefore many as much as possible for the current-sharing module band is carried, therefore require the input voltage range of current-sharing module wider, be generally 10～100VDC, even 5～100VDC, guaranteeing that the single channel output small-power power of 5V/1A or 5V/2A can be connected 16, the single channel output small-power power of 12V/1A or 12V/2A can be connected 8.The below illustrates.
For example, current-sharing module has 16 input channels, and input voltage range is that 10～100V calculates, and power calculates with every passage 180W, and input current 0～5A calculates.
So, can the wear out quantity of single channel output small-power power of 5V/1A or 5V/2A of such current-sharing module is calculated as follows: because input voltage is 5V, passage maximum 100V/5V=20pcs that can connect, consider that the output voltage when the single channel output small-power power of actual conditions 5V is unloaded may be greater than 5V, maximum can reach 5.1V, series connection 20pcs may cause current-sharing module input overvoltage and can not start shooting, therefore with 16 calculating of connecting.Current-sharing module maximum 16*16=256pcs single channel output small-power power that can wear out.If by traditional parallel energy-saving electric load aging, current-sharing module 16pcs single channel output small-power power that can only wear out, therefore the single channel output small-power power of aging 256pcs5V/1A or 5V/2A uses aging cost of the present utility model to compare with using traditional parallel energy-saving electric load, 1/16. before use cost of the present utility model only has
So, can the wear out quantity of 12V/1A single channel output small-power power of such current-sharing module is calculated as follows: passage maximum 100V/12V=8.5pcs that can connect, the voltage of considering the zero load of single channel output small-power power ranges up to 12.1V, therefore a passage series connection 8pcs gets final product.Current-sharing module maximum 16*8=128pcs that can wear out.Therefore the single channel of aging 128pcs12V/1A output small-power power uses aging cost of the present utility model to compare with using traditional parallel energy-saving electric load, 1/8. before use cost of the present utility model only has
So, can the wear out quantity of 12V/2A single channel output small-power power of such current-sharing module is calculated as follows: the power of 1pcs single channel output small-power power has reached 24W, therefore can only calculate with power the quantity of Series Sheet passage output small-power power, the quantity that one passage can be connected is: 180W/24W=7.5pcs, namely calculate with 7pcs.Current-sharing module maximum 16*7=112pcs that can wear out.Therefore the single channel of aging 128pcs12V/2A output small-power power uses aging cost of the present utility model to compare with using traditional parallel energy-saving electric load, 1/7. before use cost of the present utility model only has
In technical scheme described in the utility model, because each passage is equipped with anti-paralleled diode on the N passage series board, therefore interpolating unit is divided product, normally carrying out that product also can guarantee to wear out do not inserted in empty part position.Aging chassis still designs by 256pcs, and the single channel output small-power power of aging 5V/1A or 5V/2A is all loaded onto; Aging 12V/1A single channel output small-power power is only inserted 128 positions wherein, 128 empty getting final product in position in addition; Aging 12V/2A single channel output small-power power is only inserted 144 other empty getting final product in position of 112 positions wherein.
Above demonstration and described ultimate principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
