Title:
METHOD AND DEVICE FOR CONTROLLING PHASE LOCKED LOOP OF INDUCTION MOTOR DRIVE DEVICE
Document Type and Number:
Japanese Patent JPS6122784
Kind Code:
A
Abstract:
A controlled current inverter (CCI) induction motor drive is controlled by controlling motor current and the angle between motor flux and motor current. The angle between motor flux and current is derived directly via a microcomputer phase-locked loop synchronized to the integrated motor voltage. The delay between the application of a firing signal to a thyristor and the initiation of line current is determined and compensated for to achieve the desired angle between motor flux and motor current.
