HV-LV DC-DC Converter

Solutions

HV-LV DC-DC converter modules provide power flow between the 400-volt (high voltage) and 12-volt (low voltage) power nets or 800-volt (high voltage) and 12-volt (low voltage) power nets on hybrid electric (HEV), plugin hybrid electric (PHEV), and battery electric vehicles (BEV). These modules can be unidirectional or bidirectional, allowing power flow in either direction. Power levels from 1 kW to 3 kW are typical, with systems requiring components rated at 40 volts on the 12-volt power net and 650 volts to 1200 volts for the high voltage power net of the converter. Our discrete silicon carbide (SiC) MOSFETs, Super-Junction MOSFETs, and Automotive Power Modules (APM) give designers the flexibility to scale their solutions for existing 400-volt systems and address new 800-volt systems while delivering peak efficiencies for power conversion.
