Design and implementation of cascaded H-Bridge multilevel inverter using FPGA with multiple carrier phase disposition modulation scheme
S Chitra, KR Valluvan - Microprocessors and Microsystems, 2020 - Elsevier
The paper deals with design of Cascaded H-Bridge Multilevel Inverter (CHB-MLI) with
separate DC source to each inverter using multiple carrier Phase Disposition PWM such as
symmetric disposition, phase opposition disposition and alternative phase opposition
disposition to reduce the Total Harmonic Distortion (THD) and to improve the power quality
of the supply voltage and current. In early days, the multilevel inverters are controlled with
high frequency PWM method. This is not suitable for high power applications due to the high …
