| Summary: | Specific odd harmonics can be mitigated by operating the
simeconductor switches in H-bridge inverters at optimized switching
angles of the PWM signals. These switching angles can be achieved
by calculating a set of nonlinear equations using Selective Harmonic
Elimination Pulse Width Modulation (SHE PWM) technique.
Modulation index (m) is a significant parameter used to control the
amplitude of the fundamental output voltage of DC-AC inverter. By
changing the value of modulation index the Total Harmonics
Distortion (THD) also will change. In this paper, the influence of
varying modulation index on the THD, and the performance of Hbridge
inverter using SHE PWM scheme is evaluated. To investigate
the effect different conditions of modulation index and different
number of nonlinear equations to calculate the switching angles to
achieve a minimum THD, single phase H-bridge inverter is simulated
in Matlab-Simulink. |
