Matrix Converter
The future trends in development of power electronics converters are in high-efficiency, high power density, and high-temperature operation. These demands are important in some specific applications, such as those for hybrid vehicles, the aerospace industry, and marine electrical systems, where size and weight are limited. Currently, among the traditional power converters, the back-to-back converter is widely used in industrial applications. However, the dc-link capacitor, which is required for energy storage in back-to-back converters, not only increases the size and weight of a power converter but also provides poor performance at high temperatures and reduces system reliability. In order to overcome these drawbacks, the Matrix Converter (MC) is a well-known solution, with an absence of bulky electrolytic capacitors, which makes the power converter more compact, robust, and reliable.
Currently, my research includes:
A common three-phase to three-phase MC configuration
MC prototype designed with two DSPs (TMS320F2812) and an CPLD (Altera EPM7128)
Currently, my research includes:
- Space vector modulation (SVM) method,
- Common-mode voltage (CMV) reduction and elimination (focusing),
- Use of rotating vectors (focusing),
- Commutation techniques,
- Switching loss minimization,
- Input filter design and compensation algorithms.
