These data were taken from three oscilloscopes (Tektronix TPS 2014B, 2024B and MDO4104C) connected to an inductive power transfer system utilizing the three-phase to single-phase midpoint matrix converter with a free-wheeling switch. They were taken under various transient and steady-state conditions. The 4 attached ZIP files contain 21 CSV files in total, with its own README.txt describing the data and oscilloscope channel configurations. Additionally, each ZIP file is supplied with a MATLAB m-file script to plot the data.

Files supplement_20-TIE-2530_Matlab.zip and supplement_20-TIE-2530_Modelsim.zip complement the publication under the title "A Direct Modulation for Matrix Converters based on the One–cycle Atomic operation developed in Verilog HDL", which is under review process.

Unzip files. There are two sets: for Matlab and Modelsim. Both are presenting the idea of a modulator based on the analytic signal concept. The file "DAV_PWM.m" is an animation of the conventional matrix converter, while the content of the second zip allows for HDL simulation of the matrix converter in Modelsim from Intel FPGA company.

In this simulation, the DC voltage of the matrix converter is derived using a three-phase linear load as a sample. It shows that the voltage used by the three inverters and the average over the switching period are always the same. It also shows that when the load is constant, the DC current of the inverter is also constant.

**In this simulation, the phase difference of the signals a, b, and c in the paper is changed to 0 in 0.1 seconds from the state where the phase is 90 degrees different from the input voltage. The input current phase is the same as the above signal. Since the output voltage gradually increases, it can be seen that the DC voltage of the matrix converter increases as the phases of a, b, and c become closer to the input voltage phase. Strictly speaking, it is proportional to cosθ as described in the paper.**
