摘要： A current mode control circuit uses a current comparing module to control a switching signal according to one of a plurality of current feedback signals. The current mode circuit comprises a voltage control module that generates an output voltage according to an input voltage and the switching control signal, and that generates the plurality of current feedback signals. The current comparing module outputs a control current signal that is indicative of a greater one of the plurality of current feedback signals. A current mode control module receives the control current signal and generates the switching control signal according to the control current signal.

摘要： A boost control module operates semiconductor switches of a boost converter circuit in an avalanche mode to precharge a boost output capacitor. The boost control module comprises a switching module that complementarily transitions a first semiconductor switch and a second semiconductor switch between ON and OFF states when a current does not exceed a maximum current threshold. The switching module transitions the first semiconductor switch and the second semiconductor switch to the OFF state when the current exceeds the maximum current threshold. The switching module maintains the first semiconductor switch and the second semiconductor switch in the OFF state until at least one of the inductor current is less than or equal to a minimum current threshold.

摘要： An electrical system as described herein is suitable for use in an electric or hybrid vehicle. The electrical system includes electrical devices, such as power transistors, coupled to an electrically and thermally conductive bus bar. The respective nodes of the electrical devices are coupled to the bus bar such that the bus bar carries a combined signal generated by the electrical devices. The bus bar is also thermally coupled to a conduction heat transfer system, such as a liquid cooled cold plate. Thus, the bus bar functions as both an electrical conduit and a conduction-based heat sink for the electrical system.
摘要翻译：如本文所述的电气系统适用于电动车辆或混合动力车辆。电气系统包括耦合到导电且导热的母线的电气装置，例如功率晶体管。电气装置的相应节点耦合到汇流条，使得汇流条承载由电气装置产生的组合信号。汇流条还热耦合到传导传热系统，例如液体冷却冷板。因此，汇流条既可用作电气系统的电气导管，也可用作电气系统的导热散热器。
