Hey all, am designing a DC-AC inverter circuit. Converting 12V DC to 12V AC, then put it through a transformer to step-up the voltage. Have found a Thyristor based H-Bridge topology, but the resultant wave is either a square wave or quasi square wave. The topology can be seen here https://www.electro-tech-online.com/custompdfs/2009/04/Chapter2014.pdf
There are a couple of questions I've got:
Firstly, I was advised to use a PIC to generate the pulses to turn the thyristors on. The question I have is, for that particular topology, can the thyristors be all pulsed at the same time? Or is there a better way of controlling the circuit then using a PIC?
Secondly, with a square-wave output, what is the best way to convert it into a pure since wave? I considered using a filter, but was advised against it by my supervisor due to power losses.
If not......what other inverter circuits would you recommend?
