Spwm overmodulation
WebThe Flat Top overmodulation technique. In this technique the portion of the three-phase input signal exceeding values +/−1 is computed. The three resulting signals are then summed and removed from the original signal U ref.The resulting modified signal U ref * is therefore a flat-top three-phase signal that contains zero-sequence triplen-harmonics. . … Web12 Apr 2024 · The overmodulation phenomenon brought by the added modulation wave is analysed, which is proved to be negligible for achieving the maximum modulation index of 1.15. Finally, the effectiveness of the proposed double-modulation-wave DPWM is experimentally verified at a switching frequency of 40 kHz. ... (SPWM) with the dead time …
