Multilevel Converters for Step-Up-Transformer-Less Direct Integration of Renewable Generation Units with Medium Voltage Smart Microgrids:FPGA-Based Switching Controller

FPGA-Based Switching Controller A phase-shift or level-shift can be introduced between the carrier signals of contiguous cells to produce a phase-shifted or level-shifted switching pattern between them. In this way, when connected together a staircase multilevel waveform is synthesized. For m-level converter, (m-1) phase-shifted or line-shifted carriers are needed. The phase-shifted carriers are specially conceived […]
