Title:
ELECTRICAL DRIVING GEAR FOR SEGMENTED TRANSDUCER FOR RECTIFICATION
Document Type and Number:
Japanese Patent JPH0653566
Kind Code:
A
Abstract:
PURPOSE: To attain a technology for the electric drive of a rectifying transducer in the manner that equal mechanical powers are provided at the outputs of non-rectifying transducers. CONSTITUTION: An electric drive system has a controller 40, exciter 42, electric energy storing components 44, a switch 46 and a segmented rectifying transducer. The controller 40 is connected to an external unit to receive an activating instruction 48 and electric power 50 and upon receipt of this instruction 48 feeds the electric power 50 to the exciter 42, thereby connecting transducer segments to a resonance electric loop having the exciter 42 and storing components 44. Thus the drive system circulates the most of the electric energy for a cyclic operation, causing little loss whereby a comparatively high electric efficiency conventionally associated with the electric resonance is obtd. to provide a high drive system efficiency.
