Topdiode Mosfets Drive IC used on Electric Vehicle Conventer
The electric vehicle converter can convert the high-voltage power of the electric vehicle battery into the 12V low-voltage power required by the system. Non-isolated voltage reduction solutions are usually used in electric vehicles. Since the converter works in a relatively closed environment, heat generation is crucial to the stability of the system, so there are urgent requirements for the energy efficiency of the converter. During the operation of the entire system, low wear and damage of the power unit itself is key.
TOPDIODE ordinary Trench MOSFET series and Super Trench MOSFET series maximize energy efficiency while maintaining reasonable power consumption, comprehensively improve the switching characteristics and conduction characteristics of the device, and improve the body diode reverse recovery characteristics. In particular, Super Trench technology comprehensively improves the on-resistance temperature characteristics of the product and effectively controls the increase in device on-resistance as temperature increases. Taking 100V products as an example, compared with ordinary inductive MOSFET products, Super Trench reduces the device’s on-resistance to 175% The on-resistance multiplication factor at high temperatures is reduced from the original 2.29 to 2.09, thereby significantly enhancing the device’s current capability and impact resistance at high temperatures. Super Trench MOSFET products will be more suitable for applications in high temperature and harsh environments.
