Below in conjunction with blower fan generating, the present invention is described in further details:
First, the field effect transistor of this device is because be contained on heating panel, and heating panel needs to produce a large amount of heats, so need to carry out radiating treatment.As Fig. 1, the output of current rectifying and wave filtering circuit connects by Switching Power Supply, and the output of Switching Power Supply is connected with three terminal regulator LM7812, and three-terminal voltage-stabilizing stable output voltage supplies to fan, and fan can carry out radiating treatment.Simultaneously three terminal regulator be also connected with temperature sensing circuit, the output of temperature sensing circuit and above-mentioned overcurrent protection connection, carry out temperature detection protection by 3 pin of resistance R19, R6, R9 arrival TL494.
The boosting operation principle of this device is:
Wind-driven generator sends three-phase alternating current and exports through mainboard three phase rectifier and lead up to inductance L 1-field effect transistor Q1-diode D1 by being divided into two-way after inductor filter and boost.After inductance L 2-field effect transistor Q2-diode D2 of separately leading up to boosts, two-way parallel connection is amplified through current detector CS020 output voltage batteries charging makeup energy.
Electric current, the voltage protection principle of this device are:
16 pin of the over-current signal-R19-R6-R9-TL494 detected by 3 pin of current sensor CS020 during load overcurrent; flow through load current larger potentiometer R6 mid-point voltage lower; the 16 pin voltages of TL494 decline thereupon; 3 pin voltages are raised and sends into pulse width modulation device; TL494 driving pulse width is reduced gradually; thus reaching overcurrent protection object, C8, R20 are the feedback original paper of error amplifier.
1 pin of the overvoltage signal-R4-R3-R5-R7-TL494 of transducer CS020 output detections; more high potential device R5 mid-point voltage is lower to flow through load voltage; the 1 pin voltage of TL494 declines thereupon; 3 pin voltages are raised and sends into pulse width modulation device; TL494 driving pulse width is reduced gradually, thus reaches overvoltage protection object.
The MOSFET field effect transistor that this circuit amplifier section have employed 4 performances higher is contained on one piece of fin; the heatsink temperature that works long hours is higher, damages have employed two kinds of defencive functions: 1) connect 12V electric fan by accessory power supply and reduce heating panel temperature to heating panel blowing in order to avoid power tube Yin Wendu rising.2) detect heating panel temperature signal and current signal by temperature sensor together send into TL494 chip controls driving pulse width thus protect the damage that power tube Yin Wendu raises, make amplifying circuit reliable and stable.
Voltage is raised 50-100V through secondary voltage multiplying rectifier again by the three-phase alternating voltage of wind-driven generator by this booster circuit device after three phase rectifier.Efficiently solve middle-size and small-size wind-force send out system can not to charge in batteries in the hypodynamic situation of wind, supplement the problem that the energy content of battery consumes.Utilize when rotation speed of fan is low plug-in type supply unit also to have charging current like this, provide charging current and control system energy by booster power.When rotation speed of fan height, output voltage cuts off automatically more than 260V boosting detection system.There is provided energy by former blower fan system, if due to certain cause specific booster circuit damage time, blower fan system still normally works.(this power supply ceiling voltage is decided to be 260V, can determine according to cell arrangement) this power supply exports and is connected with output circuit through heavy-duty diode output, can avoid interference each other like this.
Normal wind generator could start generating when cutting people's wind speed 3m/s, rated speed 12.5m/s, when wind speed is 25m/s just likely there is the wild effect appearance such as the dangerous output voltage rising of driving in wind-driven generator, otherwise when incision wind speed is less than 3m/s or time calm, the effective electricity of conventional wind-driven generator is low cannot charge to storage battery, this device just improves wind-driven generator energy output under the low speed to charge in batteries effectively, substantially increase the applicability of middle-size and small-size wind-driven generator, make middle-size and small-size wind-driven generator have wide field to have business promotion to be worth.This device can make wind-driven generator send faint voltage to raise into and can charge, and increases electricity and effectively extends battery, improves the annual effective energy output of wind-driven generator.
Middle-size and small-size wind-force sends out system in the hypodynamic situation of wind, not only to charge in batteries, and can not want the performance of consuming cells.It is primarily of control system and the certain electric energy of yaw system consumption; for 10KW wind power system; wind energy system need consume and be about 500W power; to be plug-in type power supply can send small boost in voltage to existing middle-size and small-size wind generator system to this device in the hypodynamic situation of wind by wind-driven generator become voltage required for system to storage battery makeup energy, adopts inserted mode reasonable in design, defencive function is complete can not affect or change original wind generator system function.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, although the present invention discloses as above with preferred embodiment, but and be not used to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solution of the present invention, according to any simple modification that technical spirit of the present invention is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
