In this project, the design and implementation of a digital signal controller (DSC) is presented. This DSC was used for high frequency-based grid-tie inverter connected to wind emulator system. The developed DSC was designed, fabricated, and tested in our laboratory. A 150 MHz (6.67-ns Cycle Time) Texas Instruments processor chip was used as the heart of the developed control board. The DSC based board presented here is a highly integrated, high-performance solution for demanding control applications. It was designed for applications requiring a single board solution to control up to four, high frequency (HF)-based three phase converters or for general power electronics industrial applications. The main advantages of the developed DSC-board are; low cost, high processing speed capability, small size and weight, high reliability (embedded and computer independent with USB communication for program downloading process).
The developed controller was designed for controlling a 3-kW grid-connected HF-space vector pulse width modulation (SVPWM) inverter to inject the wind emulator system power into the grid. This study was also implemented in a laboratory setup for 30-kHz, 3-kW power inverter module. The experimental verification has been done in order to confirm the effectiveness of the developed controller for high frequency operation.
