Hi! Everyone.
I am doing a project on point on wave switching of an inductive load i.e. a transformer (220/110V; 275VA), begining with single phase but would like to import the solution to a three phase system and a higher rated transformer.
I am attempting to prevent high in rusuh currents at the moment of energization. The optimal point of energizing the transformer assuming zero residual flux is at supply votage peak, at this point the induced current is at zero crossing. As a result, the transformer core does not saturate.
I have considered using a light dimmer circuit to control the poinf of switching. The hurdle is that I will typically not supply full power to the tranformer.
I also need to add a zero detector circuits, to be able to track voltage peak.
I am struggling with intergration of the circuit. I would appreciate any advice or maybe a different approach to the project.
