Beschreibung
- Application circuit presents the AUX board with alternative start-up circuitry (ASC) 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
