Design considerations
- A single-phase or three-phase home grid connection has the greatest impact on design and topology choice, although charging speed is ultimately controlled by the vehicle's OBC / BMS capabilities
- Slower single-phase systems are ideal for overnight charging, although higher power 22 kW AC chargers can be also be useful for semi-public charging in parking spaces or office locationss
- To minimize BOM cost and footprint, voltage regulator with power switch integrated in auxiliary power supply is usually adopted.
- Inrush protection circuit (NTC, varistors, etc.) should be considered to prevent potential damage when charging starts
MOSFET and GaN FET Handbook
Drawing on over 20 years’ of experience, the MOSFET and GaN FET Application Handbook: A Power Design Engineer’s Guide brings together a comprehensive set of learning and reference materials relating to the use of MOSFETs and GaN FETs in real world systems.
H-bridge motor controller design using Nexperia discrete semiconductors and logic ICs
The H-bridge circuit in this Technical Note is a full bridge DC-to-DC converter allowing operation of a brushed DC motor (48 V max, 12 V min, 5 A max). All electronic functions are designed with Nexperia discrete and logic IC components (low cost, no microcontroller or software needed). Read more >>
