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.
