A mobile phone SIM card to the size of the chip, but it can carry more than 700 volts, conduction resistance, only 30 o implement efficient low consumption of energy conversion. This is the "heart" of new energy car battery pile MOSFET (metal oxide semiconductor field effect tube). Recently, the reporter understands from suzhou east micro semiconductor company, new energy vehicles dc high-power charging pile with core chip production, successfully break the monopoly manufacturers abroad.

General dc charging pile by the communication module, switching power supply module and control module, etc. MOSFET is the core part of the switch power supply module, is to achieve energy efficiency transformation, key components to ensure stable charging pile does not overheat. The cost of the MOSFET around 20% of the cost of the switch power supply module. In a switching power supply module, need to use a few hundred or even MOSFET. In the past, this area is monopolized by foreign manufacturers, domestic manufacturer of purchasing imported brands of MOSFET, not only expensive, often out of stock.

East semiconductor after two years of research and development, the original full set of patent technology, has implemented charging pile with high-pressure high-speed MOSFET series products production and application in domestic enterprise batch charging pile. At the same time, the products are also exported to South Korea, Japan and German market. At the same time, also widely used in mobile phone chargers, LED lighting, display, industrial lighting, and other areas of the power transfer.
