应用电路展示了基于反激式拓扑的AUX板，并包含作为主开关的器件SCT2H12NZ，与准谐振
控制器BD7682FJ-LB的组合。准谐振技术减少了 SiC MOSFET 的动态损耗，从而降低了其工作温度。 AUX 板能够在交流和直流输入电压下运行。因此，可以直接从电网或系统直流链路（例如在 PFC 级之后）获取电力。如果是交流输入，可接受的输入电压范围为 210 至 480 VAC。此选项对于 UPS 和工业驱动器等应用可能很有趣，其中 AUX 板的电源来自

说明

Application circuit presents the AUX board based on Flyback topology and contains the device SCT2H12NZ as main switch, in combination with BD7682FJ-LB a quasi-resonant controller. The technique of quasi-resonance reduces the dynamic losses on the SiC MOSFET and consequently lowers its operating temperature. The AUX board is able to operate with both AC and DC input voltages. It is therefore possible to derive the power directly from the grid or from the system DC link, e.g. after the PFC stage. In case of AC input, the accepted input voltage range goes from 210 to 480 VAC. This option can be interesting for applications like UPS and industrial drives, where the power for the AUX board comes from the AC grid
