Abstract

This paper presents a power loss minimization technique for a cascaded multilevel inverter using hybrid carrier based
space vector modulation. The proposal in this paper combines the features of carrier based space vector modulation and the
fundamental frequency modulation strategy. The main characteristic of this modulation is the reduction of switching loss and energy
efficiency improvements with better harmonic performance. In order to implement this hybrid modulation scheme and deliver the
hybrid PWM pulses to the appropriate switches, a TMS320F2407 digital signal processor (DSP) and a Complex Programmable Logic
Device (CPLD) are used. The inverter offers lower harmonic distortion and operates with equal thermal stress among the power
devices. Using simulation and experimental results, the superior performance of a new PWM method is shown.
