應用
電路展示了基于反激式拓撲的AUX板，并包含作為主開關的器件SCT2H12NZ，與準諧振
控制器BD7682FJ-LB的組合。準諧振技術減少了 SiC MOSFET 的動態損耗，從而降低了其工作溫度。 AUX 板能夠在交流和直流輸入電壓下運行。因此，可以直接從電網或系統直流鏈路（例如在 PFC 級之后）獲取電力。如果是交流輸入，可接受的輸入電壓范圍為 210 至 480 VAC。此選項對于 UPS 和工業
驅動器等應用可能很有趣，其中 AUX 板的

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
