Patent ID: 7170262

Claim:
A variable frequency power system for starting and powering an electrical motor load comprising: a power source with a rotating output, said power source having a speed control to regulate rotational speed of said rotating output, said rotational speed of said rotating output being rotational frequency of said rotating output; a generator coupled to and driven by said rotating output of said power source, whereby speed control of said power source directly controls output power frequency of said generator to produce a desired output frequency from said generator due to control of rotational frequency of said rotating output; a voltage regulator connected between said generator and the motor to regulate output voltage emanating from said generator for a supply voltage to an electrical motor load; and a system controller to control output power frequency of said generator to be said desired output frequency, said system controller connected to interface with said speed control of said power source; said system controller configured to monitor generator output and operational conditions of said electrical motor load, said system controller configured to adjust said speed control of said power source based on generator output and operational conditions of said electrical motor load to maintain said desired output frequency.
