High-efficiency DC/DC converter for hybrid/electric vehicles
The DCC3 converts stable low voltage from high voltage for auxiliary systems in electric and hybrid vehicles. The DCC3 converter supports input voltages from 250 to 900V, outputs secondary voltages for 12V and 24V systems, and is adjustable. The DCC3 is designed to be robust and compact, making it suitable for a wide range of applications with flexibility. Additionally, galvanic isolation between high and low voltage enhances the reliability and safety of the system. The proprietary software platform of the ZAPI Group allows for advanced customization by flexibly combining standard features, while also complying with stringent functional safety requirements.
