Design considerations
- Designers have multiple options for OBC conversion topologies, including single-phase / multi-phase and uni- / bidirectional
- Current batteries are typically 400 V, using 650 V FETs in a bidirectional OBC topology where GaN brings the highest efficiencies (for unidirectional topologies SiC diodes can be used on the secondary side
- For 800 V batteries, need to go multi-level GaN or high-voltage SiC
- However, OBC topologies are heavily fragmented which may lead to combined 650 / 1200 V device solutions
- PFC output defines blocking voltage of power semiconductors at DC-DC-Input and battery voltage defines blocking voltage at DC-DC-Output (650 or 1200 V)
- Trend towards higher OBC charging power and 800 V batteries for higher class BEV solutions, will require more 1200 V solutions
