In electric drivetrains, an inverter controls the electric motor. This is a critical part of electric vehicles, just like the engine management system (EMS) of combustion vehicles. Whether the motor is synchronous, asynchronous or brushless DC, the inverter works in a similar way, controlled by an integrated VCU and designed to minimize switching losses and improve thermal efficiency. The inverter not only drives the motor, but also recovers kinetic energy and feeds the energy back to the battery. Therefore, the working efficiency of the inverter directly affects the operating efficiency of the entire vehicle.
In response to your needs for the main inverter, Din-Tek Semiconductor provides extremely cost-effective products; the Super Trench MOSFET series products adopt shielded gate deep trench technology with charge balancing function, which comprehensively improves the switching characteristics and conduction of the device. characteristics, while reducing the characteristic on-resistance (Rsp) and gate charge (Qg) of the device, specifically optimizing the robustness of the device.
