Abstract

PURPOSE:To eliminate overshooting in case of change-over by controlling the ignition phase of a cycloconverter by a current controller formed so as to be able to adjust gains and the sum of counterelectromotive force and signals proportional to an impedance drop. CONSTITUTION:A synchronous motor 1A is wired to a cycloconverter 4, and the input currents are added to current reference value ST through a detecting circuit 8, and inputted to a current controller 11A. The current controller 11A contains a computing element 25 and a multiplier 41, and signals from an integrator 15 for adjusting gains are forwarded as one input of the multiplier 41. The output and the output of a counterelectromotive-force compensating circuit 33 and an impedance- drop compensating circuit 34 are added, and the converter 4 is controlled through a phase control circuit 12 and a change-over circuit 13. Thus, gains are decreased only for a fixed time after forward and reverse turns are changed over. Consequently, overshooting and overcurrents can be removed even when frequency increases.
