In an electric drive system, the inverter controls the motor. This is a key component in electric vehicles, just like the engine management system (EMS) in gasoline vehicles. Regardless of whether the motor is synchronous, asynchronous, or brushless DC, the working mode of the inverter is similar, controlled by an integrated VCU, designed to minimize switching losses and improve thermal efficiency. The inverter not only drives the motor, but also recovers kinetic energy and feeds it back to the battery. Therefore, the working efficiency of the inverter directly affects the overall operational efficiency of the vehicle.

In response to your demand for the main inverter, RHM Semiconductor provide products with extremely high cost-effectiveness; The MOSFET series products adopt shielded gate deep trench technology with charge balancing function, which comprehensively improves the switching and conduction characteristics of the device, while reducing the characteristic on resistance (Rsp) and gate charge (Qg) of the device, and specially optimizes the robustness of the device. Bringing high efficiency and stability to your solution while significantly saving costs.

By combining advanced packaging technology, we aim to enhance the system efficiency and power density of MOSFET devices during the energy conversion process, while ensuring their impact resistance during switching in harsh environments, achieving fast, smooth, and efficient power management and motor control.
