Wireless charging, also known as induction charging and non-contact induction charging, uses near-field induction, that is, inductive coupling, to transmit energy from the charger to the electrical device. The device uses the energy it receives to charge the battery and also to operate itself. The mainstream wireless charging standards on the market now include the qi standard, Power Matters Alliance (Pma), and alliance for Wireless Power (A4wp).
Among them, the A4wp standard is a magnetic resonance principle wireless charging standard jointly promoted by more than 40 members including Broadcom, IDT, Maps, Intel, etc., founded by Samsung and Qualcomm. The short-range magnetic resonance technology used by a4wp can charge multiple devices at the same time, and is flexible in the position and angle of the devices. Its charging capacity and time are also in line with consumer expectations. It is an advanced product that represents an important trend in the future. Among them, maps (mixed Analog Power Solution) has a number of proprietary wireless magnetic resonance charging technologies, and has a strong competitive advantage in fast charging time and application versatility when compared with Samsung's wireless charging technology.
Semipower, as a strong participant in the competition in China's semiconductor power device industry, is currently cooperating with maps, which owns multiple a4wp wireless magnetic resonance charging equipment patents and has been mass-produced. It is actively introducing advanced technology to settle in China and invited maps company on March 6 President Joon Rhee visited semipower. This cooperation received great attention from the leaders of the Shaanxi Provincial Department of Commerce. Mr. Tang Yugang, deputy director of the Department of Commerce, made a special visit to semipower to express his support and expressed high appreciation for semipower's active introduction of world-leading technology. President Joon Rhee expressed his gratitude to Semipower General Manager Luo Yi for the invitation. China is currently the largest semiconductor manufacturing and consumer country in the world. It can be said that the future of world semiconductor development lies in China. Maps will also continue to cooperate in depth with Semipower to strengthen wireless magnetic resonance. Promotion and application of charging technology in the Chinese market.
2017 is a critical period for fully implementing "Made in China 2025", deepening innovation-driven efforts, and striving to achieve steady industrial growth and improve quality and efficiency. semipower will continue to strengthen cooperation and exchanges with international advanced semiconductor companies, learn from advanced experience, and make our contribution to the development of China's power device industry.
