Web控制器mosfet的功率损耗随着电机负载的加大而增加，当电机堵转时，控制器的mosfet损耗达到最大（假设控制器为全输出时）。 为了分析方便，我们假设电机堵转时B相上管工作在PWM模式下，C相下管一直导通，B相下管为同步整流工作方式（见图1）。 WebThis work reports on the self-heating effect (SHE) characterization of HV DMOSFETs and the accurate extraction of the equivalent thermal impedance of the device (thermal …

WebDrain-source on-resistance (RDS (on)) is the resistance between the drain and the source of a MOSFET when a specific gate-to-source voltage (VGS) is applied to bias the device to the on state. As the VGS increases, the on-resistance generally decreases. The measurement is made in the ohmic (i.e. linear) region of the device.
