With a specific embodiment explanation the present invention, illustrate as example below with single cover winding generating terminal voltage.Specified charging voltage value 29.6VDC as energy storage component, the Charge Management device itself has 3 times wide pressure process range, be m=3, the output voltage of then corresponding single cover winding generating end all is an effective voltage at 21VAC-63VAC, can both be through the charging of Charge Management device treatment and supplied energy storage component.Voltage as simplex winding output is 10.5VAC, if do not pass through this circuit, then this voltage is dead voltage, and after the foregoing circuit series connection, voltage is upgraded to original 2 times and becomes 21VAC, effectively; Voltage as simplex winding output is 12VAC, if do not pass through this circuit, then this voltage is dead voltage, and after the foregoing circuit series connection, voltage is upgraded to original 2 times and becomes 24VAC, effectively; Voltage as simplex winding output is 15VAC, if do not pass through this circuit, then this voltage is dead voltage, and after the foregoing circuit series connection, voltage is upgraded to original 2 times and becomes 30VAC, effectively; Voltage as simplex winding output is 20VAC, if do not pass through this circuit, then this voltage is dead voltage, and after the foregoing circuit series connection, voltage is upgraded to original 2 times and becomes 40VAC, effectively,
And the voltage of the 21VAC-63VAC that sends for the generator simplex winding is originally just in the effective voltage scope, need not to boost, therefore many covers winding this moment output voltage of simplex winding that promptly directly uses in parallel gets final product, when being 22VAC as the voltage of simplex winding output, constant the getting final product of above-mentioned two cover windings sustaining voltage value in parallel this moment, in like manner, when being 30VAC, during 40VAC as the voltage of simplex winding output, during 50VAC, all allow the voltage that the above-mentioned two cover windings magnitude of voltage that keeps exporting to the Charge Management device in parallel is exactly the output of generator list cover winding get final product during 60VAC.
As seen, the voltage of the 10.5VAC-63VAC that simplex winding generating end sends is all effective, make the effective voltage scope become 10.5VAC-63VAC by original 21VAC-63VAC, wide pressure scope has become 6 times, 2 times on 3 times basis, have been promoted again, the voltage of the disabled 10.5VAC of the script that generator windings is sent～21VAC section also can be the energy storage component charging, has made full use of power generation energy resource, improves the utilance of generator.Boost during series connection, electric current is constant, and voltage is constant when in parallel, and electric current increases.
The foregoing description has been narrated the connections of two cover windings, also can be 3 covers, 4 cover windings, when overlapping winding, connects by above-described mode between per two cover windings more, overlaps between the positive-negative output end of winding to be in turn connected to form series loop more; Be connected to form the shunt circuit between connection and the negative output terminal between the positive output end.Because this is that those skilled in the art are easy to expect according to above-mentioned annexation, therefore do not described in detail at this.The words of 3 cover windings, the output voltage of 7VAC-63VAC is all effective, the words of 4 cover windings, 5.25VAC-63VAC output voltage all effective, every increase by one cover winding, wide pressure scope just expands and is twice, prevented the waste of the energy, the utilance of generator is just high more, during with above-mentioned two cover windings in like manner, so do not repeat them here.For two covers, the situation of two-phase phase place symmetric winding, identical with above-mentioned three phase windings, circuit such as Fig. 5, the first winding RZ1 ' connects first bridge rectifier of being made up of diode D1 '-D4 ', the output of first bridge rectifier connects first inductance L 1 ', the second winding RZ2 ' connects second bridge rectifier of being made up of diode D10 '-D13 ', the output of second bridge rectifier connects second inductance L 2 ', described switching circuit comprises three powerful gate-controlled switches, be respectively switch N1 ', switch N2 ' and switch N3 ', the power pin of switch N1 ' connects the negative output terminal of the first winding RZ1 ' and the positive output end of the second winding RZ2 ', the described first bridge rectifier first electric capacity E1 ' in parallel, the first electric capacity E1 ' is connected between the power pin of the positive output end of the first winding RZ1 ' and switch N1 ', the described second bridge rectifier second electric capacity E2 ' in parallel, the second electric capacity E2 ' is connected between the power pin of the negative output terminal of the second winding RZ2 ' and switch N1 ', switch N2 ' connects the positive output end of the first winding RZ1 ' and the positive output end of the second winding RZ2 ', switch N3 ' connects the negative output terminal of the first winding RZ1 ' and the negative output terminal of the second winding RZ ', the negative output terminal of the positive output end of the first winding RZ1 ' and the second winding RZ2 ' is connected described Charge Management device U1, and the Charge Management device connects energy storage components such as storage battery.Above-mentioned inductance and electric capacity all are filter actions, and principle is identical with above-mentioned three phase windings, so do not give unnecessary details.
Treatable maximum when handling magnitude of voltage for exceeding the Charge Management device, this part power supply is an inactive power sources, the Charge Management device can't be handled, can't supply with energy storage component, the words that accumulate on Charge Management device internal circuit certainly will be damaged the components and parts of Charge Management device, therefore described Charge Management device also comprise one when the magnitude of voltage of the detected single cover winding generating end of Charge Management device greater than described Charge Management device institute treatable maximum handle magnitude of voltage/
Or single cover winding dc terminal voltage value is greater than m

By Blast Furnace Top Gas Recovery Turbine Unit (TRT) such as solar energy, when body-building device or wind-force are the energy storage component charging, because these energy sources all are unsettled, therefore voltage can the time little when big, therefore in a single day can not detect change in voltage just switches, row switches and will detect after the voltage condition more fully, does not stop the problem switched in order to avoid switching device occurs, causes potential safety hazard.
