2维TM波matlab程序，FDTD PML (FDTD PML)

This example of AC-DC-AC converter illustrates use of Universal Bridge, Multimeter, and Powergui blocks, as well as discrete control blocks of the Extras library.(A 60 Hz, voltage source feeds a 50 Hz, 50 kW load through an AC-DC-AC converter. The 600V, 60 Hz voltage obtained at secondary of the Wye/Delta transformer is first rectified by a six pulse diode bridge. The filtered DC voltage is applied to an IGBT two-level inverter generating 50 Hz. The IGBT inverter uses Pulse Width Modulation (PWM) at a 2 kHz carrier frequency. The circuit is discretized at a sample time of 2 us)

如何使用Matlab混合编程？这本书就告诉你！挺好用的。不过好像版本低了点，现在matlab升级了，可能会有比较大的变动。(How to use hybrid programming in Matlab? This book will tell you! Very good use. But it seems the version of the low points, matlab upgrade, there may be changes.)
