Key Points

  • This research aims to develop a control method for multilevel converters to optimize photovoltaic energy output.
  • Introduced a new proportional PWM modulation technique.
  • Implemented independent maximum power point tracking for each H-bridge module in the system.
  • Evaluated performance in grid-connected scenarios.
  • Each H-bridge module successfully operated at different power levels.
  • Independent tracking improved overall energy extraction from photovoltaic arrays.

Abstract

This paper introduces a new control method and proportional PWM modulation of the cascaded H-bridge multilevel converter for grid-connected photovoltaic systems. This control makes each H-bridge module supply different power levels, allowing therefore for each module an independent maximum power point tracking of the corresponding photovoltaic array.
