Title:
CONTROL ARRANGEMENT OF DYNAMO-ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JP2019198206
Kind Code:
A
Abstract:
To provide a control arrangement of a dynamo-electric machine capable of restraining reduction of controllability of the control amount of the dynamo-electric machine.SOLUTION: A control arrangement includes a field control section for controlling a field current, flowing through a field winding, to a field command current If*, a synchronous rectification control section, a sine wave control section, and a transition control section. When switching is made from control of the sine wave control section to control of the synchronous rectification control section, the transition control section controls the field control section so that the field current, immediately after switching to control of the synchronous rectification control section, becomes larger than the field current immediately before switching to control of the synchronous rectification control section, and when switching is made from control of the synchronous rectification control section to control of the sine wave control section, controls the field control section so that the field current, immediately after switching to control of the sine wave control section, becomes smaller than the field current immediately before switching to control of the sine wave control section.SELECTED DRAWING: Figure 12
