Hi,
I'm currently tasked to build a 20Vdc to 230Vac(rms) inverter but I'm not sure which approach will be better to build. Can someone please comment based on your valuable experience and expertise. The following are the two approaches that I have in mind.
Approach 1:
First, design a DC DC boost converter to boost the 20Vdc to 325Vdc (Peak) than use this 325Vdc to inverter to 325Vac(Peak) where I can get 230Vac(rms)
The DC AC Inverter i'm having in mind is using a full bridge SPWM topology where 4 IGBT switches will be used.
Approach 2:
First, I will design the inverter so that it can convert 20Vdc to 20Vac(Peak) by using a full bridge SPWM topology where 4 IGBT switches will be used.
Than use a step up transfomer to step up the 20Vac(Peak) to 325Vac(Peak) so that I can obtain 230Vac(RMS).
