  • Analysis of brushless three‐phase synchronous generator without exciter
    Brushless self-excited single-phase synchronous generators developed by Nonaka [1-31 produce constant output voltages without using automatic voltage regulators and are used widely as portable generators inside and outside Japan.
  • Generating plant for military equipment
    7.3) Voltage Regulation The automatic voltage regulation of small portable generators deserves a paper to itself, and it is to be hoped that one will be forthcoming from some member ofThe Institution better qualified than the present author. Regulators for large static machines have been available for many years and are discussed in many publications …
  • Analysis of voltage-adjustable brushless synchronous generator without exciter
    The output voltage is kept constant under the wide variation of load without using an automatic voltage regulator . Nowadays this generator , with fractional kilowatts to several kilowatts, is widely used as a portable engine generator.
  • Brushless three‐phase synchronous generator without exciter
    This generator requires no exciter and, in particular, in the single phase synchro- nous generator utilizing the negative phase sequence magnetic field, terminal voltage can be maintained constant without using an automatic voltage regulator . Hundreds of VA and several kVA portable generators ex- tensively available on the market include this feature.

  • Self‐regulated self‐excited brushless three‐phase synchronous generator
    Most generators employed in portable gen-sets are brushless self-excited synchronous machines, combining exciters and rotary rectifiers. In addition, an external device such as an automatic voltage regulator (AVR) is necessary to compensate for output voltage changes.
