Patch-Based Matrix-Free Time-Domain Method and PML Truncation in Unstructured 3-D Meshes

Abstract: In this article, we propose a new time-domain method for solving Maxwell’s equations: patch-based matrix-free time-domain (P-MFTD) method, in unstructured 3-D meshes. This method is free of ...

A Novel Discontinuous PWM Method With Hybrid Three-Step Commutation to Reduce Common-Mode Voltage for Direct Matrix Converter

Abstract: The conventional discontinuous pulsewidth modulation (PWM) can provide several advantages in a direct matrix converter (DMC), such as less switching number and less execution time for ...
