The control of power and energy sources to optimize a performance metric (i.e. maximize efficiency, minimize energy storage) has received considerable attention with the emergence of microgrids. In this research, power management models have been developed for two classes of electric machine/converter systems. Specifically, in the first class, a wound rotor synchronous machine/diode rectifier connected to a fixed DC output is considered. Relationships between commanded DC power, mechanical input power, and field winding current are established. In the second class, a buried magnet synchronous machine connected to an inverter is considered. The relationship between the mechanical power, AC power, and stator winding current amplitude and phase are derived. Both models are validated by comparing their respective behavior to those of detailed models that include switching of the semiconductor devices.
