• H02P 9/02 Details
• H02P 9/04 Control effected upon non-electric prime mover and dependent upon electric output value of the generator
• H02P 9/06 Control effected upon clutch or other mechanical power transmission means and dependent upon electric output value of the generator
• H02P 9/08 Control of generator circuit during starting or stopping of driving means, e.g. for initiating excitation
• H02P 9/1 Control effected upon generator excitation circuit to reduce harmful effects of overloads or transients, e.g. sudden application of load, sudden removal of load, sudden change of load
• H02P 9/14 by variation of field
• H02P 9/4 by variation of reluctance of magnetic circuit of generator
• H02P 9/42 to obtain desired frequency without varying speed of the generator
• H02P 9/44 Control of frequency and voltage in predetermined relation, e.g. constant ratio
• H02P 9/46 Control of asynchronous generator by variation of capacitor
• H02P 9/48 Arrangements for obtaining a constant output value at varying speed of the generator, e.g. on vehicle
