The microprocessor based modified space vector control of the matrix converter

In recent years, PWM matrix power converters have been studied for eliminating the DC links of conventional power converter and inverter systems. A new method, based on space vector modulation, has been proposed which is more effective than the traditional PWM. In this paper, the development of this method is investigated. The forming of the required averaged space voltage vector is obtained without using zero vectors. It enables the reduction of the number of commutations and the increase of the output/input voltage ratio. A microprocessor based control system is also presented.
