Outline of Final Research Achievements

The matrix converter that can directly convert from the constant AC voltages of a power supply to AC voltages with variable voltage and variable frequency is attracted as a high-efficiency and high-power-density power converter. However, the PWM strategy has been not schematized due to the complex control method.
In this research, the PWM strategies for suppressing the harmonics are derived and schematized, and the visualized PWM strategies are developed. The research contents are three items of “Derivation of PWM strategy for reducing the output harmonic voltage”, “Derivation of PWM strategy for reducing the input harmonic current” and “Visualization of PWM strategies”. This research results contribute diffusion and practical realization because of easy understanding of the control method for the matrix converter.
