Abstract: A control method for preventing saturation of a transformer during fast voltage changes by correction of magnetic flux of the transformer, the transformer having a primary winding with a power electronic converter and a secondary winding, the control method including estimating or measuring a primary signal including a primary voltage on the primary winding of the transformer and a primary current on the primary winding of the transformer, and injecting a correction signal including a correction voltage into the primary winding of the transformer so as to prevent saturation of the transformer.
