20 lead automotive batteries (12V / 96Ah each) are connected in series forming 240V DC source.
It is easy to create converter to 240 V square pulse AC source by full H-bridge using powerful MOSFETs. But how to create good 50Hz sine waveform? Suppose AC load could consumes up to 20A (approx. load of 5kW). Precise sine generator from a micro controller over DA converter and optocoupplers is not an issue. The main problem is which elements to use for
energetic part. Some ideas with thyristors or IBGTs ?
Any kind of idea?
thanks
