Prior types of generating systems for producing AC and DC output power have utilized integrated drive generators for producing the AC power and means for rectifying the AC power developed by the drive generator to produce the DC power. However, such types of systems encounter various disadvantages, including less than desirable reliability of the DC power, distortion in the AC power caused by rectification thereof to produce the DC power and reduced efficiency. In order to overcome these problems, a hybrid generating system according to the present invention comprises an AC power generating section driven by a prime mover for generating AC output power and a DC power generating section independent of the AC power generating section, also driven by the prime mover for generating the DC output power wherein each of the AC and DC power generating sections includes a permanent magnet generator. The AC and DC power generating sections may be provided in a common housing to provide a compact hybrid generating system in which reliability and efficiency are increased and distortion in the AC output power caused by generation of the DC output power is eliminated.
