Computer controlled large power narrow pulse system

Abstract

A computer-controlled large-power narrow-pulse system belongs to the high-new technical field of bioengineering and suits bioengineering use. The system is composed of a three-phase isolating transformer (0), thyristor current inverting power devices (1, 2), filter devices (3, 4), a large-power narrow-pulse inversion sub-system (5), a power pulse drive device (6), a computer digital control sub-system (7), a high-frequency high-voltage transformation device (8) and an electric field device. The large-power narrow-pulse inversion sub-system is composed of insulated gate bipolar transistors IGBT serving as the power switch elements, and has the advantages that the IGBT can be integrated and can apply soft switching technique. The computer can control on and off of the power switch elements IGBT according to application software, and can control the thyristor current inverting power devices to convert a controllable DC voltage to an alternating high-frequency pulse voltage, which is outputted after being boosted by the high-frequency high-voltage transformation device. The input power is a three-phase AC voltage with a magnitude of 380-10% to 380+10% and a frequency of 50-2% to 50+2%, and the output voltage has a magnitude of 40 KV to 80 KV, a frequency of 1 KHz to 5 KHz, a power number of 10 KW and a pulse width of ns to mus. The computer-controlled large-power narrow-pulse system has the advantages of high voltage, large power, high frequency, narrow pulse, and computer-controllable pulse parameter, and can save the energy resources to achieve large social and economic benefits.

Description

technical field [0001] The computer-controlled high-power narrow-pulse system belongs to the high-tech field of bioengineering. Background technique [0002] In the field of bioengineering technology, food sterilization usually adopts the technology and method of heating and drugs, which inevitably destroys the nutrition and vitamins of the food, and it is difficult to maintain the original color and taste of the food. Heat sterilization consumes a lot of energy; drug sterilization , Residual pharmaceutical ingredients in food are not ideal. [0003] The purpose of the invention is to provide a computer-controlled high-power narrow-pulse system to sterilize food, which can quickly kill spoilage bacteria and pathogens in food (such as beverages, milk, fruit puree, liquid cake, etc.), without destroying the nutrition of food and vitamins, maintain the original color and taste of food, use this system to stimulate fruits and vegetables, rupture the nucleus, produce more fruit ...
