Description of the Invention: [Technical Field] The present invention provides a multi-electrode poultry stun device and method, and more particularly, a combination of a dither voltage and a stunner voltage in a multi-electrode manner Electrosonic stun device and method for slaughtering poultry. '[Prior Art] In recent years, the theme of animal welfare has received increasing attention, especially before slaughtering livestock or poultry, they must be slaughtered in an unconscious and painless manner to meet the requirements of humane slaughter. At present, there are two commonly used methods for human body slaughter and stun. The carbon dioxide (C02) coma method and the electric shock coma method, in which the carbon dioxide coma method requires a large space, long fainting time and high cost, limits its application. Therefore, the electric shock stun method is generally used in the stun of livestock or poultry. The quality of the meat is highly correlated with the electrical parameters of the electric shock. In the method of electric shock stun in poultry, the degree of coma is mainly determined by the amount of current flowing through the animal. In order to achieve sufficient stun current, the voltage applied to the surface of the animal must be sufficient to cause skin breakdown on the animal's surface. Therefore, when electric shock is used to faint livestock or poultry, the stun mechanism mainly uses current to flow through the central nervous system to suppress the conduction of nerve signals. However, the current to suppress the transmission of nerve signals should be large enough, but too much stun current will lead to a decrease in the quality of the meat. Therefore, the characteristics and stability of the stunner affect the quality of the meat. Most of the stunners currently used in domestic slaughterhouses use the stunners developed by domestic manufacturers. According to their power supply, they can be divided into mains power supply systems and battery-powered systems. 5 Refer to the first figure for a schematic diagram of the fainting of poultry in the utility power supply system. At the same time, referring to the second figure, it is a block diagram of the mains power supply system. The mains power supply system for stunned poultry generally uses a silicon steel sheet step-up transformer 1 to directly boost the low-frequency mains power supply AC to the shock voltage AC〇 required for fainting poultry or livestock. Referring to the third figure, it is a schematic diagram of a conventional battery-powered system that stuns poultry. At the same time, refer to the fourth figure, which is a block diagram of the battery power supply system. The battery-powered system of the fainted poultry uses a DC/DC converter 10 to cut the battery voltage Vi into a square wave voltage Vd, which is then converted to a uniform faint voltage V0 via a DC/AC converter 12. In the design of the conventional stunner, the two stun structures of the electrodes A and B are used, as shown in the first and third figures. Due to the two-electrode A and B fainting structure, a higher stun voltage is required to promote the skin collapse of the poultry, which will result in excessive stun current and affect the quality of the meat. In addition, in the above mentioned stunner system, the function of no voltage regulation and current limiting protection is easy to generate excessive stun current, which affects the quality of the meat, and the system is bulky and inefficient. SUMMARY OF THE INVENTION In view of the above, the present invention provides a multi-electrode poultry stunning device and method, which combines a dither voltage and a stunner voltage to call a poultry in a multi-electrode manner. In turn, the quality of the carcass is improved and animal welfare is improved. The multi-electrode poultry stunning device of the present invention includes a voltage converter, a disturbance voltage generator and a uniform faint voltage generator. The voltage converter is used to convert a reference voltage into an output voltage. A disturbance voltage generator is operative to receive the reference voltage and to output at least one disturbance voltage. The stun voltage 1321451 generator is connected to the voltage converter to receive the output voltage and output a uniform faint voltage. The multi-electrode poultry stun method of the present invention comprises the steps of: first, preparing a poultry; then applying at least a high frequency and high voltage disturbance voltage to the poultry to destroy the skin impedance of the poultry; finally, applying A consistent faint voltage is applied to the poultry to stun the poultry by electric shock. The above summary and the following detailed description are exemplary in order to further illustrate the scope of the claims. Other objects and advantages of the invention will be set forth in the description and drawings. [Embodiment] Referring to the fifth and sixth figures at the same time, the fifth figure is a schematic diagram of the multi-electrode poultry fainting device of the present invention, and the sixth figure is the circuit block of the multi-electrode poultry fainting device of the present invention. Figure. The multi-electrode poultry stunning device 2 includes a voltage converter 20, a disturbance voltage generator 22, and a uniform dim voltage generator 24. The voltage converter 20 is used to convert a reference power Vi into an output voltage V01. The disturbance voltage generator 22 is for receiving the reference voltage Vi and outputting the disturbance voltages Vd1, Vd2. The stun voltage generation 诣 24 is coupled to the voltage converter 20 for receiving the output voltage V 〇 : and outputting a uniform faint voltage V0. The multi-electrode poultry stunner 2 of the present invention is a poultry that is driven by a voltage output by three electrodes A, B, and C, wherein the disturbance voltages Vdl and Vd2 are high voltage and high frequency alternating voltages, respectively, from the electrode AC. Output with BC and applied to the poultry to be slaughtered so that the poultry skin collapses quickly. The stun voltage V〇 is output from the electrode A-B and applied to the poultry to be stunned to the poultry. This first uses the disturbance voltages Vdl, Vd2 to cause the poultry skin to collapse quickly and then apply the stun voltage V. The way to reduce the use of the stun voltage 7 1321451 v〇, and thus reduce the voltage that the poultry should withstand when it is stunned ___ _..... — -- 10,000 ~ ^ 7 luxury poultry pressure, To improve the quality of the meat of poultry. With reference to the sixth figure, referring to the seventh figure, the circuit diagram of the multi-electrode poultry fainting device of the present invention is shown. The voltage converter 20 used in the multi-electrode poultry stunning device 2 is implemented by an active clamped flyback converter including a first transformer Tr, a resonant inductor LK, and a resonant capacitor C. !, an output diode D5, an output capacitor C 〇 and a synchronous switch group ly ^, M2. The disturbance voltage generator 22 is implemented by a half bridge converter including at least one diode DrD4, a CLC series-parallel line (CB, Ls, Cs), a second transformer Tr2, and The synchronous switch group]\^, M2. The stun voltage generator 24 is implemented as a full bridge converter. Referring back to the seventh figure, the active clamped flyback converter used in the multi-electrode poultry stunning device 2 can recover the leakage inductance energy of the transformer T, and can make the synchronous switch group Μ!, M2 have zero during the on state. The effect of voltage switching (ZVS). In conjunction with the signal waveform diagram of the multi-electrode poultry stunning device of the present invention shown in the eighth embodiment, the following is a description of the mode of operation of the multi-electrode poultry stunning device 2 of the present invention. Mode l[t〇St<tl]: Before t0, the switch and M2 are in the off state, and the bypass diodes DM1, diodes Dj and D3 on the switch are in the forward bias state. At this time, the voltage across the winding % is V〇/N, where N is the turns ratio of the transformer 1\. At the same time, the crossover voltage of the switch Μ! is also zero. When t = t0, the switch Μι is turned on, and the switch Μι operates at the zero voltage switching ZVS state. During this period, the magnetizing inductor current 1^ and the secondary side current ID5 exhibit a linearly decreasing state. 8 1321451 Mode 2 [tl<t<t2]: When t = tl, the switch Μ stays in the on state. At this time, the switch current IDS1 and the leakage current ILk are both zero. Since the load energy is supplied by the energy stored in the excitation inductance Lm during this period, the diodes D3 and D5 are still in the forward biased direction.旲3[t2S t<t3] · At t = t2, the inductor current is equal to the magnetizing inductor current ILm, at which time the current Ini is equal to zero, so the diode current ID5 is equal to zero, so that the diode D5 is in the reverse bias. During this period, since the inductor current ks is still maintained at a positive value, the diode D3 is in the flywheel state due to the inductance Ls, and the flyback converter is also in the energy storage state. Mode 4 [t3<t<t4]: When t = t3, the inductor current ILs reaches zero. Therefore, 'diode D3 is reverse biased' and 〇4 is forward biased. During this time, the inductor current Ils flows through the diode D4 and the switch Μ!' to maintain the inductor current continuously. Mode 5 [t4<t<t5] ·· When t = t5, the switch 吣 is turned off, and the parasitic capacitance Cmi stored in the leakage inductance Lk, the excitation inductance Lm, and the inductance Ls is released to the switch. Mode 6 [t5S t < t6]: At time t5, the voltage VDS1 across the parasitic capacitance CM1 is equal to the input voltage Vi, at which time the diode D4 is reverse biased, and the diode D! begins forward bias To maintain the inductor current ILs continuously. During this time, the parasitic capacitance CM1 is charged by the inductor current ILk, and its voltage varies from Vi to Vi + Vq/N. When t = t6 hires the voltage across the switch to Vj + ν0 / Ν, then the diode D! is in the forward bias. Therefore, the voltage VN2 across the secondary winding Ν2 is clamped at V. And the primary side winding voltage ν Ν 1 is clamped at vQm. Since the voltage across the capacitor C! is approximately Vi + VQ/N, the parasitic diode DM2 of the switch M2 is in a forward bias. In addition, the inductor Lk and the capacitor C! also form a resonant network and are cycled for a period of nine cycles. Under the load, the measured electricity:: and the graph of =M1 at 50% of the full nine maps can be found in the multi-electrode poultry of the present invention::: waveform diagram: zero-turn by the first-stage converter system; Actively clamped anti-faint device 2 and conventionally: == effect; = 日日月彡® not, as can be observed from the tenth figure, this is not used and used in the =_ system ==: wide ^j · The voltage of the transmission ==: The sub-shed is shown in the material - A picture and material - _, in the tenth = flow, because of the 'small S-induced disturbance of the power to generate enough voltage sensation of fainting poultry, In turn, good things are obtained: i can = home = % of the faint period and output power to display the disturbance electrical disturbance voltage, the amplitude will decrease.
