Overview

A starter reference model of three-phase LLC converter based on eHS HSCS solver.

This is a three-phase LLC converter reference model using square-wave modulation, with resistive load. The primary three-phase H-bridge operates at 121 kHz switching frequency and 45% duty ratio, and the secondary side uses uncontrolled rectification. Real-time simulation via RT-LAB eHS HSCS (32 ns time step) is carried out to verify system steady-state characteristics and benchmark against offline SPS simulation.

Key Features

  • The model is simulated with the latest eHS HSCS solver, with a minimum time step of 32 ns.

  • Steady-state performance is demonstrated, and the obtained results show high consistency with SPS model results.

  • Bi-directional will be updated in the future release.

Hello @Aks

This zip file is downloadable, can you please try again? If it does not run on your software version I’ll suggest to check once the compatibility of the versions.

Thanks
