Abstract

An alternator generates output power at two or more independent voltages (V A ,V B ). The alternator has two independent output windings (110,112) configured to generate the power needed for each output (126,128). Each output voltage (V A ,V B ) is sensed by a regulator (106) that controls switching rectifiers (114,116) to supply the current needed to satisfy the electric power demand of the loads (102,104) connected to each output (126,128). After both output load demands are satisfied, the regulator (106) switches off the alternator field (108). When power demand from either load (102,104) rises, the alternator field (108) is switched on along with the respective switching rectifier (114,116) to satisfy the power demand. The output voltage grounds and control signals may be electrically isolated from each other.
