DC/DC conversion HV/LV
The low-voltage (LV) power circuits in modern electric vehicles (12 V or sometimes also 48 V) are primarily supplied from the high-voltage (HV) drive battery. The converter, with a typical power class of 1.5 kW to over 3 kW, converts the HV direct current – which varies depending on the battery configuration and charge status – into stable LV power.
Innovation & trends
- High control dynamics, including in vehicle power circuits without a backup battery
- Bi-directional conversion to pre-charge the high-voltage system
- Greater efficiency thanks to wideband gap semiconductor technologies
Performance data & available functionality
- Wide DC voltage ranges in 400 V or 800 V voltage classes
- Power class 1.5 kW - 2 kW or 3 kW - 3.5 kW
- Maximum output current: 250 A (example for 3 kW converter with 12 V)
- High-voltage and functional safety plus cybersecurity in line with current standards and any applicable specifications of the vehicle architecture
