Abstract
To supply intermittently required high-power loads, such as heater applications in an automotive vehicle, a dual armature winding three-phase alternator has a first or main winding connected to a first or main rectifier bank to supply power to vehicular loads, for example at 12 V nominal level; an auxiliary winding is connected to a rectifier which can be switched to operate as a half-wave rectifier, in parallel with the main winding and main rectifier to supply the ordinary loads when high-power loads are not connected; or to be switched in a full-wave bridge rectifier configuration to provide additional power at elevated voltage, added to the voltage of the rectifier receiving current from the main windings, for example providing 16.multidot..sqroot.3=28 V added to the nominal supply voltage of 12 V=40 V voltage to the heater load.
