Title:
METHOD AND FREQUENCY CONVERTER FOR CONTROLLING INPUT POWER FACTOR OF FREQUENCY CONVERTER
Document Type and Number:
Japanese Patent JPS5839272
Kind Code:
A
Abstract:
The input power factor of an AC to AC static power converter is continuously adjustable between a maximum leading or lagging phase angle, determined by the load power factor, through rapidly transferring between conventional and complementary unrestricted frequency changer operation with the proportion of each sub generator cycle interval dedicated to each mode of operation being selected to produce the desired input power factor. Since the input power factor affects generator excitation, the input power factor control can be used in a closed loop feedback control system to regulate generator voltage.
