Abstract

The formation of semiconductor switching strategies for power converters based on preprogrammed switching patterns begins in the second half of the 20th century. The main idea of the strategies is to modulate the converter output voltage with a defined harmonicspectrum. It should be noted that it is difficult to control the harmonic spectrum at a low switching frequency of converter semiconductor modules using classical pulse-width modulation (PWM) methods, such as sinusoidal PWM or space-vector PWM. The low switching frequency in the range from 150 Hz to 900 Hz is a consequence of limited capabilities of the semiconductors of converter power ratings above one megawatt. The development and research of the switching methods of semiconductor modules for high-power converters are the most relevant directions due to their well-known problems in electromagnetic compatibility, power quality and switching losses leading to overheating. There are some scientific articles presenting the effectiveness of changing the modulation methods, but the changing algorithm is not considered in detail. This article is devoted to the development of an algorithm for changing strategies for preprogrammed pulse-width modulated (PPWM) for a three-level converter. The requirements for the developed algorithm are formulated on a modulation index, a shift angle of the output converter voltage and power converter semiconductor module states. Experimental studies were carried out on laboratory equipment and the efficiency of the proposed algorithm was shown. The prospects of research results for high-voltage converters are determined.
