Introductiom
SSSPWM full name is Symmetically Synchronized Sine PWM，the meaning reference as below： “Carrier Synchronous、Full symmetrysinwavePWM Modulate。You can see from the figure below (left), by LS unique wave algorithms, between the inverter output phase voltage and line voltage has physically【Symmetrical】、【Point symmetry】Special effects; the purpose is to completely eliminate the low order frequency (sub) harmonics and reduce the high octave (super) harmonic components
