ONSEMI APM32 series includes a trio of silicon carbide (SiC) based power modules in transfer molded technology that are intended for use in on-board charging and high voltage (HV) dc-dc conversion within all types of electric vehicles (xEV). The first-of-its-kind that adopts SiC technology into a transfer molded package to enhance efficiency and shorten charge time of xEVs and is specifically designed for high-power 11-22kW on-board chargers (OBC). Each of the three modules exhibits low conduction and switching losses, combining with best-in-class thermal resistance and high voltage isolation to deal with 800V bus voltage. The enhanced efficiency and lower heat generation ultimately allow for a more powerful OBC. One that can charge the xEV faster and increase its operating range – two critical factors for consumers.
