The smooth R&D and production of the JLQZ-80 and JLQZ-100 series cutting rigs will further enhance the company's overall design and manufacturing level. At the same time, the company will achieve greater benefits in the fiercely competitive market economy and improve the company's brand awareness. (This article comes from Jiang Yan Li Gong)
For street lamps, higher efficiency and longer life are indispensable for cost reduction.Designed for the LED power supply switch power supply, also must have a high efficiency and durability, to ensure that it has as long as the LED life without maintenance.Here, the resonant converter is one of the most popular power supply topology, this is because compared with previous power supply topology, their performance has brought higher power efficiency, and can reduce EMI.Soft switch is an important characteristic of resonant converter.But the resonant converter used in parasitic diodes (bodydiode) can sometimes lead to system failure.Stored in the parasitic diodes charge must be clear, to avoid large current and voltage surge, including topology structure of high dv/dt and di/dt.
At present, the domestic construction machinery market continues to be sluggish, especially the excavator industry is facing a severe market economy test, while the domestic market for cutting rigs is indeed unique and the potential market demand is strong. Heavy Industry Technology Co., Ltd. and machinery manufacturing company strong combination, independent research and development of JLQZ-80, JLQZ-100 series cutting drilling rig. On the basis of making full use of the mature technologies of CN70 and CNl50F excavators, the secondary design and development and system integration of systems such as structure, power, platform, electrical, and hydraulic pressure are carried out. After meticulous design and manufacture by both parties, the prototype has been fully assembled in early June. After relevant tests, the prototype has reached the leading domestic level.
