Switching Product Development

Although most companies are emphasizing customization capability enhancements, many are pursuing R&D on low noise, intelligent control, compact structure, and high efficiency, frequency and reliability.

The target applications are also a key consideration in product development. The computer and peripherals segment, for instance, requires units with high power and reliability, and circuit protection. Demand from this industry is expected to increase by 10 percent.

Zhongshan Xiaolan Hui Yang has launched a slim AC/DC adapter that is 17mm thick. The model is for laptops. The company is also obtaining a patent for its Power-over-Ethernet adapter. The unit boasts low energy consumption and elevated capacity and efficiency with EMI and EMC conforming to FCC3 and CISPR B standards.

Shenzhen Shanjing Power Supply Co. Ltd offers what is said to be the smallest in-car notebook PC charger. Measuring 105x30x20mm, the type delivers more than 94 percent efficiency.

Machinery, power systems and rail transport are likewise predicted to steer R&D in years to come. Figures from Beijing JFUnited Consulting Co. Ltd show that lathe lines are the number one consumers of switching power supplies in the first sector with a market exceeding $28.5 million. This is followed by food packaging, textile and heavy equipment.

On average, makers allot 5 percent of total sales to product development. Some cooperate with local universities and research institutes for technology improvement.
