HV - LV DC-DC converters are essential for modern electric and hybrid vehicles, enabling efficient power transfer between high voltage (HV, 400 V or 800 V battery architecture) and low voltage (LV) power nets. These converters support a wide range of applications in HEV, PHEV and BEV electric vehicles, providing reliable energy management for both propulsion and auxiliary systems.
onsemi's solution platform offers scalable, modular architectures for both unidirectional and bidirectional power flow, allowing designers to optimize energy distribution and system flexibility. Typical converter power levels range from 1 kW to 5 kW, with components rated for 40 V - 100 V on the LV side and up to 1200 V for HV operation. The interactive block diagram guides engineers through system integration, highlighting best practices for power electronics and topology selection, ensuring safety compliance and redundancy.
With advanced silicon carbide EliteSiC MOSFETs, Super-Junction (SJ) MOSFETs, and Automotive Power Modules (APM16 and APM32), our solutions deliver peak efficiency and reliability for both 400 V systems and 800 V platforms. Design your vehicle's electrical architecture with robust DC-DC conversion, seamless integration, and future-ready performance for every challenge.
