modelTransformer1PhaseWithHysteresis
Single-phase transformer with ferromagnetic core and hysteresis
Extends from Interfaces.ConditionalHeatPort (Partial model to include a conditional HeatPort in order to describe the power loss via a thermal network).
Information
Simple model of a single-phase transformer with a primary and a secondary winding and a magnetic core. The core is modeled with GenericHystTellinenEverett flux tube elements. Thus, this element considers static and dynamic hysteresis.
