I WANT TO KNOW THAT IN AN IRON CORE TRANSOFRMER INVERTER DESINE WHAT FREQUEENCY OF TRIANGULAR WAVE WILL BE MODULETED WITH THE 50HZ SIGN WAVE REFERENCE?
Or even Sine Wave?
"Sine" and "Sinus" both being short for "Sinusoid" (or "Sinusoidal")
en.wikipedia.org/.../Sinusoidal
Of course, nobody can understand your problem if you can't (or won't) explain it clearly...
