Engineering notes, selection guides and standards comparisons for teams specifying on-board charging hardware. Written for OEM, Tier-1 and distributor engineers.
OBC and DC/DC Converter Software Requirements for Vehicle Integration
OEM integration of OBC and DC/DC software depends on defined CAN diagnostics, controlled bootloading, protected calibration, cybersecurity interfaces, and disciplined configuration change management.
EV DC/DC Converter Functional Safety: What OEM Buyers Should Request
OEM buyers should request a converter safety case, defined safety goals, isolation strategy, diagnostic coverage, fault reactions, and objective supplier evidence aligned with the vehicle-level safety…
OBC Input Current Harmonics and Power-Factor Correction for Fleet Vehicles
OBC input-current quality depends on PFC topology, control strategy, grid impedance, and vehicle operating mode. A disciplined validation plan helps fleets avoid nuisance trips, overheating, and…
OBC Power Density: Thermal Design and Cooling Interface Requirements
OBC power density depends on more than switching frequency. Topology, semiconductor packaging, thermal paths, coolant limits, layout and vehicle interfaces together determine usable output, derating margin…
How to Dual-Source OBC and DC/DC Power Semiconductors
A practical framework for identifying single-source semiconductor risks, qualifying electrically compatible alternatives, and maintaining OBC and DC/DC production without redesigning the vehicle electrical architecture.
OBC and DC/DC Integrated Unit vs Separate Modules
Integrated OBC/DC/DC units reduce packaging and interface work, while separate modules improve serviceability, design flexibility and fault isolation. The right choice depends on thermal architecture, validation…
How to Specify OBC and DC/DC Converter CAN Integration
Specify CAN integration before component selection: define signals, timing, diagnostics, wake-up, fault reactions, cybersecurity interfaces and software ownership so the OBC or DC/DC converter fits the…
OBC and DC/DC Converter DV PV Testing Plan
A practical DV/PV plan for OBC and DC/DC programmes, covering requirements, electrical and thermal validation, EMC, insulation safety, environmental stress, and automated production end-of-line testing.
How to Qualify an OBC Supplier for Automotive Production
A production-ready OBC supplier must prove more than electrical performance: verify design ownership, manufacturing controls, traceability, validation, capacity, change discipline and ramp readiness.
