Abstract

This paper deals with the study of the pulse-width modulation (PWM) methods of autonomous inverters control. The three PWM methods are analyzed. A model enabling study of all considered PWM methods is created via the Matlab/Simulink software. Essential characteristics of the PWM methods are obtained. The vector simplex PWM method is outlined as the most appropriate for control of the autonomous inverter at remotely operated underwater vehicles. The fundamental component of output voltage and voltage conversion ratio are high enough in this case to meet all requirements to the power supply systems of the remotely operated underwater vehicles. Moreover, the method ensures a good harmonic composition of output voltage.
