摘要： A circuit and method for compensating for parasitic elements of a transistor. A transistor, a controller, and a compensation element are mounted to a printed circuit board. The transistor includes parasitic drain and source inductors. The compensation element may be a discrete inductor that has an inductance value equal to about the sum of the inductance values of the parasitic drain and source inductors. The magnitudes of the compensation voltage and the sum of the voltages across the parasitic drain and source inductances are substantially equal. Thus, the compensation voltage developed across the compensation inductor is used to adjust a reference voltage within the controller. A drain-to-source voltage is applied to one input of a comparator within the controller and the adjusted reference voltage is applied to another input of the comparator. An output signal of the comparator is input to drive circuitry that drives a gate of the transistor.
摘要翻译：一种用于补偿晶体管的寄生元件的电路和方法。将晶体管，控制器和补偿元件安装到印刷电路板。晶体管包括寄生漏极和源极电感器。补偿元件可以是离散电感器，其具有等于大约是寄生漏极和源极电感器的电感值之和的电感值。补偿电压的大小和寄生漏极和源极电感之间的电压之和基本相等。因此，在补偿电感器两端产生的补偿电压用于调整控制器内的参考电压。漏极 - 源极电压施加到控制器内的比较器的一个输入端，调整后的参考电压被施加到比较器的另一个输入端。比较器的输出信号被输入到驱动晶体管栅极的驱动电路。
