Title: (EN) DIODE CONDUCTION SENSOR
(ZH) 二极管导通传感器
Abstract: front page image
(EN) Methods and apparatus for a body diode conduction sensor configured for coupling to a switching element are disclosed. In embodiments, the sensor comprises first and second voltage divider networks coupled to a voltage source and a diode coupled to the switching element and to the first voltage divider network, wherein the diode is conductive at times corresponding to body diode conduction of theswitching element decreasing the DC average voltage at the output node of the first voltage divider network. A differential output voltage can be coupled to the first and second voltage divider networks with an output signal corresponding to a time of the body diode conduction of the switching element.
(ZH) 用于被配置用于耦合到切换元件的体二极管导通传感器的方法和装置。在实施例中,传感器包括耦合到电压源的第一和第二分压器网络;以及二极管,耦合到切换元件和第一分压器网络,其中,二极管在对应于切换元件的体二极管导通的时间是导通的,从而降低第一分压器网络的输出节点处的DC平均电压。差分输出电压可以耦合到第一和第二分压器网络,其中输出信号对应于切换元件的体二极管导通的时间。
