Why we are used fixed DC supply instead AC power supply in inverter circuit? Why do we need to convert DC POWER? What happened when we direct AC supply supply to inverter circuit?

Efficient DC supply eruntha you have to use DC to AC for inverter circuit only here not required for AC supply

@@electricnmore3398 Sir, சந்துரு sir..... கேட்ட மாதிரி... AC to DC convert பண்ணது அப்புறம் straight line தானே wave form கிடைக்குது அதுல இருக்குற சின்ன சின்ன sine wave ripple செய்து pure DC மாத்தியாச்சு.. அதாவது AC... Wave ல frequency இருக்கும்.. DC wave ல frequency இருக்காது.. இப்போ இந்த DC straight wave எடுத்துட்டு போய் நீங்க சொன்ன IGBT க்கு input கொடுக்கும் போது.. Alredy இது DC circut..எப்படி சின்ன சின்ன squre sine wave output கொடுக்குது. இல்லை IGBT DC to AC மாத்தி addtional ah.. Squre wave ah motor க்கு கொடுக்குதா?? இதுல

@@madhuvimal88 Hello Brother, That is modified sine wave generate by IGBT or MOSFET method of SPWM(Sine Pulse Width Modulation).That signal coming from Microcontroller or Mosfet Driver.Same like on off state in high speed switching pulse
