Below in conjunction with blower fan generating, the utility model 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.
