Title:
ENERGY CONVERTER CONTROLLER
Document Type and Number:
Japanese Patent JP3765287
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an energy converter controller capable of measuring errors in a mover position by a simple constitution.
SOLUTION: When a current supplied to a field winding r exceeds a predetermined value, a large current is generated. The value of such a current as not to generate power is taken as the predetermined value. A current whose value is equal to or less than the predetermined value is supplied to the field winding, and an induced voltage is measured. Since the induced voltage corresponds to the position of a mover, the position of the mover can be learned from the induced voltage. In this case, an error in the position of the mover can be measured using the position of the mover measured based on a different basis in addition to the position of the mover thus determined.
