Pure sine wave inverter design and circuit

[george_leon]

As i have already told -ve of 325v DC will swing from 0v and -325v. So 18v aux supply without isolation will result in short circuit.

pls,give us the circuit for 18v auxillary since you have build it before.

Hi George! How did you get ride of core´s saturation in such a medium power push pull design?

Thanks in advance.

Hi Simao Berkof!

Unregulated push-pull converters are self-balancing if enough dead time and a gentle Vds rise ramp at turn-off is provided.

how much power is needed for the 325v dc ?

It depends on for how much power you are designing.

Thank you so much can you give the transformer winding details and winding direction (e.g) anti clock wise or clock wise etc.

I have given dot in diagram indicating winding direction.
