onsemi’s APM32 sequence of SiC-based energy modules handles on-board charging and high-voltage DC/DC conversion in all varieties of electrical automobiles. Among the many first to undertake SiC know-how in a switch molded package deal, the gadgets improve effectivity and shorten the cost time of EVs and plug-in hybrid EVs.
Particularly designed for high-power 11-kW to 22-kW on-board chargers (OBCs), every of the three modules within the APM32 sequence displays low conduction and switching losses, in addition to best-in-class thermal resistance and excessive voltage isolation to take care of 800-V bus voltages. These options permit for a extra highly effective OBC that may cost an EV sooner and enhance its working vary.
Two modules within the APM32 sequence, the NVXK2TR40WXT and NVXK2TR80WDT, are configured in a half-bridge topology with a breakdown functionality of 1200 V, making them well-suited for high-voltage battery stacks. They’re meant for use within the OBC and HV DC/DC conversion levels. The third module, the NVXK2KR80WDT, is configured in a Vienna rectifier topology and used within the energy issue correction (PFC) stage of the OBC. Six-pack and full-bridge modules are deliberate for the close to future to finish the SiC OBC portfolio.
The highest cool and remoted options of the DIP gadgets meet probably the most stringent automotive business requirements. Creepage and clearance distances adjust to IEC 60664-1 and IEC 60950-1. Moreover, the modules are certified to AEC-Q101 and AQG 324 for automotive use.
