Abstract: PURPOSE:To realize shift shock suppressing control corresponding to the variation of the friction coefficient, and to obtain an adequate shift feeling, by correcting the torque converting amount in the speed change time larger than a standard value, when the familiarity between the fastening materials of friction fastening elements is not sufficient, and the friction coefficient is small less than a specific value.

Abstract: PROBLEM TO BE SOLVED: To reduce the burden of load at a high-input power factor by outputting the control signal of a power control section, while using the output signal of a multiplying means and the detecting signal of DC current detection as inputs. SOLUTION: A chopper 2 consists of a DC reactor 3, a diode 4, a transistor 5 and a DC capacitor 6, and the DC capacitor 6 is charged by a current from a rectifier 1 and DC voltage VDC is outputted when the transistor 5 is turned off, and voltage VDC is lowered when the transistor 5 is turned on.

An output from a DC voltage control section and the full-wave rectified signal of single-phase input voltage are multiplied and used as a current command signal, and an input current is formed in an equivalent sine wave form while employing the DC current of the full-wave rectifier 1 as a detecting signal at the time of a single-phase input.  The signal is changed over to a reference DC-voltage setting signal and multiplied by a DC voltage signal, and the chopper 2 is controlled as the command value of a current wave form at the time of a three-phase AC. Accordingly, the burden of load can be reduced at a high-input power factor.
