Abstract


It’s proposed a dual randomization of Hybrid Space Vector Modulation (HSVM) for a full bridge three phase inverter. Both of the switching frequency and the pulse position are simultaneously randomized. A unified principle of switching functions generation based on a random triangular carrier is first proposed. Then, by use of the switching functions, a general analytical model of Power Spectral Density (PSD) is established for both of output phase to ground voltage and phase to phase voltage. PSD analysis shows that the proposed dual randomized modulation scheme allows obtaining the best spread shape comparatively to simple randomization schemes.
