Among them, the main power signal is connected to the power supply nickname, such as + 5 V, ± 12 V, or + 3.3 V 'secure', and the voltage level of the standby power signal is usually the price. Supply crying $ 2 material will Zhao Xian, causing the increase of the temperature of the electric green 14 heart two senses, so it is necessary to design - the scatter to set up the overlay: =! The temperature of the internal environment of the device 2 to avoid the temperature (four) 仏成屯The source supply 2 Yun Weisheng a, n a sign and called 罝 _ μ lost or burned. In this embodiment, the power RP 7G is respectively connected to the power switch .19, the temperature sensing module 15 wide modulation circuit 22, and the temperature system module 15 is disposed at the power supply side to detect the power supply 2 inside. The temperature of the environment: No. 2: The required signal to be measured; the micro control unit 21 receives the detection signal f 24 and the diode 23 and the main power source _ several power sources 2 receive the main power signal or the standby power signal, and according to the control The signal is used to generate a pulse width modulation signal: Finally, the heat sink 14 receives the pulse width modulation signal, and operates according to different pulse widths of the pulse width signal (green) and different duty cycles. For example, #散敎装置】* When the cooling fan is used, the higher driving frequency or the higher the operating cycle will make the cooling fan have a higher rotation speed. The Yin, temperature sensing, and module Μ can be achieved by using the thermistor, but it is not limited to the use of the 雹 雹 以 .. 10/18 M384344: The power supply 2 of this embodiment has a main power supply I2 and — = 'The main power supply 12 can be based on the power-on switch 12's turn-on signal. f At this time, the standby power supply 13 is not turned off, but it is not exported to the outside of the power supply 2; and when the main power supply 12 is switched] When the signal is turned off and the main power signal is stopped, the standby power signal of the original 13 is exported to the external electronic device (not shown) in the standby mode of operation, so that the control unit 21 can connect to the signal. In this way, this creation micro drive power supply. In this way, regardless of the _ job number as its 赤曰鲜τ#_α•电尉, should be in the normal working mode: Micro-control unit 21 can maintain normal operation. "Connecting with the main f and the standby unit 1 24 and the diode carrier μ to obtain the main power signal or the standby (four) signal, respectively, and the switch 24 is controlled, the switch 24 can be the Mos element switch 19, wherein When H κ 开启 ' is turned on, when the power switch 19 is turned on. The domain power supply 2 is switched from the "normal operation mode", and the main power supply 12 outputs a main two: to - turn-on signal: := body voltage standard:: signal And according to the production of higher _ level: road one 2: J two «. Therefore, in the normal guard mode, the scattered pulse sees the double operating power to dissipate heat, thereby allowing rapid high internal environment temperature Reduce the package source supply benefit 2 positive off 19 generate _ off signal, then positive - switch to - standby mode, and the main power 'two: lose 11 / 18 plus Wei # ϋ, when the switch 24 according to the signal Without conduction, the pulse width = circuit 22 can obtain the standby power supply through the diode 23 = the second pulse width modulation signal of the lower voltage level. Therefore, in the standby mode, the heat dissipation device 14 can be used in a single operation. , continue to heat, borrow = reduce the overall power supply 2 power supply ^ lower: according to In the authoring embodiment, when the strict sound inside the power supply 2 increases, the temperature sensing mode, the group 15 will generate a strong = hold = =: element 2 control pulse width modulation circuit 22 produces a higher = Modulation signal, so that the heat sink 14 can be cooled compared to = 1 . Therefore, if the heat sink U is a cooling fan, the speed of the fan will increase with the power supply. The amount of electricity inside the power supply 2 can be discharged more quickly to the internal ring_temperature of the two-source supply 2. On the other hand, if the temperature of the human-particles is at a lower temperature state, the temperature sensing mode, and then w generates a weaker detection signal, and the micro control unit 21 controls the pulse width circuit 22 to generate a pulse width modulation signal device having a lower_cycle, that is, the heat can be dissipated at a lower operating power. According to the different internal temperature of the power supply 2, the operating power of the device, and the device 14 are flexibly adjusted. When the internal temperature is high, the operating power of the heat sink 14 is controlled to rapidly reduce the internal ambient temperature. At lower internal ambient temperatures , control the lower operating power of the heat sink 14 rate to the section: the power loss of the overall power supply 2 ....., • ·. Factory · . . . · zj. r, · ten. ~, , that is, the 'supply, the power supply II 2 is in - is expected to be sheet metal. 9 or - standby mode., the temperature sensing module 15 will continue to sense (,; "power supply .2,: The internal temperature is in gold and the micro control unit u also senses the intensity of the detection signal of the group 15 according to the overflow rainbow, and the pulse width modulation circuit is passed through the pulse width modulation circuit; 12/18 control and adjust the operating power of the heat sink 14. In summary, the power supply 2 of the present invention can have - temperature sensing = magic 5 to detect the internal ambient temperature of the power supply 2, and accordingly A sub-signal 'difficult element 21 can generate a corresponding control period 〇 pulse width modulation signal according to the 控制 号 (4) degree to generate a corresponding control signal , pulse width modulation circuit 22, then the heat dissipation device M can correspond Different temperatures operate at uninterrupted operating power. Moreover, when the power supply 2 is in a positive === wide modulation circuit 22, the pulse width modulation signal will have a moving (four) (eg, 12 volts); when the power supply is in the - standby mode The second pulse width of the pulse width modulation circuit 22 is a low driving voltage (eg, 5 volts).
