Real time simulation of matrix converter drives

This paper describes a real time simulator of matrix converter system. The simulated plant is a classical matrix converter with source, input filter and load. The simulator is based on the RT-LAB real time simulation platform, which enables easy model-to-target designs from Simulink models. The simulator is designed to accept real IGBT/GTO/MOSFET firing pulses from high performance I/Os thus permitting matrix converter controller testing in hardware-in-the-loop (HIL) simulations. The matrix converter models use interpolation methods to obtain variable step-solver equivalent precision in the fixed time step scheme required by HIL applications. This paper highlights the special techniques necessary to simulate kHz-range inverters
