As electric vehicle (EV) technology advances, the performance of onboard chargers (OBCs) has become a critical factor in vehicle efficiency and driver satisfaction. Meeting this demand requires accurate modeling and testing of power factor correction (PFC) front-end topologies and DC-DC converter stages under realistic operating conditions.
To meet these demands, Typhoon HIL has introduced enhanced capabilities in its ultra-high-fidelity real-time simulation platform designed to support OBC development. The platform enables engineers to evaluate a wide range of PFC topologies, including single-phase and three-phase designs.
An extensive model library includes rectifier and active power factor correction (APFC) configurations, such as totem-pole and Vienna rectifiers, supporting detailed, real-time testing of grid-connected OBCs.
DC-DC conversion remains a central function in ensuring efficient and stable power delivery to vehicle batteries. Typhoon HIL’s platform provides an environment for testing diverse DC-DC converter topologies, including resonant and dual-active bridge designs.
The enhanced resolution solver offers 25-nanosecond resolution for DC-DC converter simulation, enabling in-depth analysis of switching behavior and transient responses. This allows engineers to verify designs for efficiency, reliability, and safety while reducing development risks.
The platform also supports testing against variable grid conditions, including voltage sags, frequency variations, and electromagnetic disturbances. With its intuitive workflow and hardware integration, engineers can streamline design iterations, accelerate validation, and ensure compliance with grid standards.
Typhoon HIL’s advancements in real-time simulation aim to help engineers shorten development cycles while strengthening the performance and reliability of EV charging systems.
