new three-phase LLC resonant converter design is great for EV charging because it has a wide gain range. variable magnetizing inductance and two-stage control make it really efficient. experiment results show that it’s 97.7% efficient, which is exactly what the theoretical analysis said it would be

Understanding the operating principles of this enhanced three-phase LLC resonant converter is critical for engineers and practitioners in the field. The use of variable magnetizing inductance combined with a two-stage control strategy not only extends the gain range, but also improves overall system efficiency. These improvements can lead to more effective and adaptable EV charging solutions, ultimately contributing to the growth and efficiency of the electric transportation infrastructure.
