Abstract:
1. A power system comprising: an AC load and a DC load; an alternator operating at a varying voltage and frequency, the alternator connected so as to supply power to the AC load; rectification and regulation means to rectify and regulate at least some energy from the alternator so as to supply DC power to the DC load at a desired DC voltage, wherein the desired DC voltage is above a zero to peak value of the alternator under at least some operating conditions, wherein the rectification and regulation means contains a capacitor and a diode connected in parallel from a first terminal of the alternator to a circuit terminal, and wherein the rectification and regulation means further comprises a first rectification means connecting the first terminal to a second terminal of the alternator and a second rectification means connecting the second terminal so as to supply power to the DC load; and means for monitoring the DC voltage supplied to the DC load and preventing the DC voltage from rising above the desired voltage by controlling the second rectification means.
