100 W Auxiliary Power Supply Eval Board BD7682FJ-LB-EVK-302
This document describes an evaluation board consisting for a 100W auxiliary power supply solution around the BD7682FJ AC/DC quasi-resonant flyback control IC and the SCT2H12NZ, a 1700V SiC MOSFET.
BD7682FJ-EVK-402 Evaluation Board User's Guide
For driving SiC (Silicon Carbide) MOSFET. The evaluation board outputs 24 V voltage from the input of 300 Vdc to 900 Vdc. The output current supplies up to 1 A.
BD7682FJ-EVK-301 Evaluation Board User's Guide
For driving SiC (Silicon Carbide) MOSFET. This 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, after the PFC stage. In case of AC input, the accepted input voltage range goes from 210 VAC to 480 VAC. In case of DC input, the input range goes from 300 VDC to 900 VDC.
