Introductiom

SSSPWM full name is Symmetically Synchronized Sine PWMthe meaning reference as below“Carrier SynchronousFull symmetrysinwavePWM ModulateYou can see from the figure below (left), by LS unique wave algorithms, between the inverter output phase voltage and line voltage has physicallySymmetrical】、【Point symmetrySpecial effects; the purpose is to completely eliminate the low order frequency (sub) harmonics and reduce the high octave (super) harmonic components
