The control coupling switch device is configured to control the switching device to perform cutting, so that the switching device outputs an AC output voltage. According to an exemplary embodiment of the present invention, the charge pump circuit solid diode is composed of N capacitors, where N is a positive integer. In an exemplary embodiment in accordance with the present creation, the output voltage is at least 4 kV when the negative cut is the ion fan 5 M4380V3. - The creation uses a two-stage boosting method. The first stage uses the charge pump to boost the second stage of the second and second stages. Therefore, the 'i turn (four) is limited by the device space. Enhance the power _ ° Another side - this creation _ sub-wind heat sink can be used in the 限 limited space 'ion fan module can operate at the output voltage and carry out the heat and heat dissipation effect. (4) The ion fan is fanlessly fanned. There is no traditional fan noise, wind ride, fan dust or large volume. In addition, the ion wind heat sink of the present invention has the advantages of small size, no moving parts and energy saving compared to the conventional fan heat sink. In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following detailed description of the embodiments and the accompanying drawings will be described below. [Embodiment] An exemplary embodiment of the present invention will now be considered as a moxibustion in a detailed embodiment, and an example of the exemplary embodiment will be described in the accompanying drawings. Where possible, the same reference symbols will be used throughout the drawings to refer to the same. In the following embodiments, when an element is referred to as being "connected" or "coupled" to another element, it may be directly connected or spliced to the other element, or there may be intervening elements. Relatively, when an element is referred to as being "directly connected" or "directly coupled" to another element, there is no intervening element. 1 is a schematic 6 view of an ion wind heat sink in accordance with an embodiment of the disclosure. Please refer to Figure 1. From + 11 〇 and ion wind money = thermal device just included voltage conversion device at the input to VlN and ions. The voltage conversion device 11G is electrically connected to the input voltage Vw to form a DC voltage between the group 12G and the group 12G to increase the DC module 12 〇 (load) to the voltage (high ink) ν 〇υ τ to the ion fan. The human voltage VlN can be a general description of the rovers ~ refers to the voltage value of the thousand sample level: the meta-changing device 110 includes a DC-AC conversion single two: the direct, the input voltage 4 is converted, thereby output-crossing (4) Surface-connected DC/AC conversion unit Rainy ▲ This voltage conversion device 110 performs boosting in two stages. In the first stage, the transformer 3G performs boosting. The second stage of the Hunan charge pump circuit 6〇 performs another boost. . The DC-AC conversion unit 10 includes a controller 20 and a switching device 24 based on a pulse width modulation architecture. The switching device 24 receives the DC input voltage vin. The controller 20 is coupled to the switching device 24 . The controller 20 controls the switching device 24 to switch by means of pulse wid A modulation (PWM), whereby the switching device 24 outputs the AC output voltage Vaco to the primary winding 40 of the transformer 30. During the first stage boosting process of the transformer 30, the secondary winding 4〇 and the secondary winding 50 are magnetically coupled to the same transformer core, and M438073 is boosted to generate an AC induction dragon Αα. The secondary side winding 5Q is used to raise the level of the original input voltage Vin, wherein the level of the AC output voltage Va(7) is between +VJN and ^. Further, the primary side winding 4〇 and the secondary side winding 50 may have a numerical ratio of ηκ. Please note that the transformer (10) of this creation does not have a high turns ratio to boost, so the transformer in the voltage conversion device 110 does not have a large volume compared to the conventional transformer, which helps to configure the transformer 30. In a limited space of equipment. On the other hand, since the transformer 30 does not use a very high area ratio, the loss between the primary side winding and the secondary side winding 50 is not serious or even negligible. The charge pump circuit 60 is coupled to the secondary winding 4〇 of the transformer || During the second-stage boosting process, the 'charge pump circuit 6' is configured to receive the AC induction, press Vaci, and boost the AC induced voltage VACI to generate an output voltage V〇^T', wherein the output voltage ν 〇υ τ is The high voltage required for the ion fan module is provided, and the output turn Vqut can be 丨Μ ν·, ^ Ν is a number greater than 1. In another example, the output voltage vOUT can be designed to be at least 4KV or more, but the value of the output voltage V〇ut of the present application is not limited thereto. θ When the ion fan module 120 applies a high voltage of 4KV or more, a corona phenomenon will occur under the strong electricity %, so that the air ions move to generate an electric wind, or ion wind, to drive the air through the ion fan module 120. The body is cooled. Therefore, the electronic device equipped with the ion wind heat dissipating device 1 can generate a heat dissipating effect due to the principle of thermal convection. Since the ion fan module =0 is fanless, there is no problem with conventional fan noise, fan squeaking, fan dust or large volume. Moreover, the ion wind heat dissipating device 1GG of the present invention has a small fan-shaped, non-moving part and a Wei-Wang source, and has the advantages of a body and a small airflow for cooling. Variable control to reduce the output voltage. , "Working" is a must-have circuit construction and operation: == so that those with ordinary knowledge in the field can better understand the spirit of this creation and implement this creation. 凊Refer to Figure 1. Implement here For example, the opening 24 can include switches 25, 26, 27, and 28, wherein the switches 25, 26 can be p-type metal oxide semiconductor (PMOS)' and the switch 27 28 can be n-type gold oxide. The semiconductor (n_type metai 〇xide semiconductor, NMOS ) 'but not limited to this. The controller 20 based on the pulse width modulation architecture can control the switches 25 to 28 in full bridge mode for switching. The full bridge driving mode can be as follows When the switches 25 and 28 are turned on, the switches 26 and 27 are not turned on; and when the switches 26 and 27 are turned on, the switches 25 and 28 are not turned on. Therefore, the energy conducted to the primary winding 40 is reflected on the primary winding 50. The controller 20 and the switching device 24 are designed in a full-bridge driving manner. In addition, in still another modified embodiment, the controller 20 can be changed to a half-bridge driving mode, and the switching device 24 is controlled by a half-bridge driving method. Inside Switching of each switch. Please note that the driving method of this creation should not be limited to the above possible types. For the design of the transformer 3〇, the turns ratio of the primary winding 40 to the secondary winding 50 can be 1 ·· κ For increasing the voltage M438073 vAC0 of the primary winding 40 by a factor of κ. For example, the sine wave of the secondary winding 4 振荡 oscillates between the level and -VrN, and the sine wave of the secondary winding 5 反应 is The oscillation between the levels +vP and -vP, where v produces κ χ Vin, and Vaci=k χ Vaco 〇 charge pump circuit 6〇 is coupled to the secondary winding 4〇 of the transformer 3〇. Charge pump circuit 6 The receiving AC induced voltage should be boosted by the voltage VACI and generate an output voltage. The private voltage νουτ is the high voltage required for the ion fan module 12〇. Therefore, the output voltage VOUT can be 1 to ΝVaci. It is noted that the charge pump circuit 6 is composed of N diodes and N electric valleys, where N is a positive integer. For example, the charge pump circuit 60 includes a circuit body composed of a pole body 62 and a capacitor 64. , using the voltage step-up principle to multiply the voltage. ^ Figure 2 shows the Figure 1 A schematic diagram of the waveform of each node voltage of the sub-winding heat sink 100 as a function of time. Please refer to FIG. 2 and FIG. 2. The voltage of the node N〇 is VACI, and the sine wave of the AC induced voltage Vaci is approximately +Vp to -VP. The oscillation is called. The voltage of the node is %, and the sine wave of voltage % oscillates between 2Vp and 〇. The voltage of node N2 is V2, and the DC voltage of voltage % is about 2Vp; more precisely, the DC of V2 Size = 2 X (K xVjn _ vF) ' % is the forward voltage of the diode. The voltage at node 为 is V3, and the sine wave at voltage V3 is approximately between 3VP and 2VP. At node N, the -output voltage ν· is supplied, and the output voltage v is hidden by the DC size = 2 X Ν X (Κ χ Vin · Vf). Therefore, in this embodiment, the value of V〇UT can be easily calculated by VIN, K and N, etc., and 10 M438073 is obtained. Example t' is designed to output 4VV or 4KV to 4KV. High voltage and high electric field required for the back end. Note that the value of 输出10 output voltage ν°υτ can be obtained by L, so that when the ion wind 4 is applied with a voltage, the air is driven to pass through the body of the ion fan module 120 and the heat of the device m towel is dissipated. The important features of this work, the ion wind cooling device of this creation: The device uses a two-stage boosting method for the rafter, the first stage is controlled by the transformer = pressure, and the second stage is boosted by the charge pump, so it can be effectively solved. The traditional problem is that the voltage cannot be increased due to the device space. The ionic air heat sink of this creation can be applied in a limited space, and the ion fan module can operate at the output voltage and operate, and produces 3 effects. Since the ion wind group is fanless, it does not cause fan noise, fan life, fan dust or large volume. In addition, the original ion wind heat sink is compared to the conventional fan device. With the advantages of small size, moving parts and energy saving, the ion wind cooling device (4) of this creation can be lightened, which increases the convenience of application and use. The evaluation of the above-mentioned preferred embodiments and circuit analysis provides an efficient alternative to mass production in comparison to the conventional technology.
