Weichuang electric won three national invention patents
Recently, Weichuang Electric has obtained three national invention patents, namely "a multi-level high-voltage flyback switching power supply", "structure and installation and disassembly method for connecting PCB board and inverter rectifier module", "simple pulse switching power supply PWM generation circuit and method", and obtained the invention patent certificate issued by the State Intellectual Property office.
The invention patents cover switching power supply, power electronics and structure design. The invention patent of "a multilevel high voltage flyback switching power supply" is to improve the structure of the switching power supply and convert the input power into multi-level voltage, which not only improves the input voltage, but also solves the problem that the high voltage can not be input. The way of small current series connection not only solves the problems of high voltage withstand and serious heating caused by direct series connection of MOS transistors, but also solves the problem that MOS transistors cannot have excessive current, which widens the application range of switching power supply.
The invention patent of "structure for connecting PCB board and inverter rectifier module and its installation and disassembly method" effectively solves the installation problems in the existing methods, such as inconvenient disassembly, low assembly efficiency, PCB board deformation, height difference, and potential safety hazard caused by parts falling into the cabinet during disassembly, and has the advantages of convenient installation and disassembly, meeting strong current demand, and meeting various height differences It has the characteristics of using demand, convenient operation and high work efficiency.
"Easy pulse" The invention patent circuit of "pulse switching power supply PWM generation circuit and method" is simple, cost-effective, full hardware implementation of the circuit, the whole processing process does not need the intervention of CPU and other control circuits, and has high reliability, which effectively solves the defects of large chip size and many pins in traditional technology; and the peripheral circuit of this circuit only has resonance module and dead time setting module, which makes pulse switching power supply The source volume is minimized.
With the increasingly fierce competition in the industry, technological innovation and R & D strength are the key to maintain high-speed development and continuous leadership. Weichuang's R & D team has been committed to improving product performance for a full range of research, relying on the real insurance room resources of key colleges and universities, always taking scientific and technological innovation as the guide, and has achieved fruitful results
The acquisition of the three invention patents is due to the company's continuous R & D investment, complete talent training and reserve mechanism, firm and clear product line strategy, and dynamic innovation platform, which has accumulated rich resources in innovation and scientific research achievements, directly related the research and development achievements with the main technologies, and applied them to the production of the company's entire series of products. The invention patent achievements have accumulated the driving force for the future development of the company, further enhanced the technical gold content of Weichuang products, enhanced the product stability, improved the core competitiveness of the enterprise, and provided strong scientific and technological support for the sustainable development of the company.
