Title: Method and apparatus for giving of lock of phase-locked loop system from frequency sweep
Inventor: FURANSESUKO KAROBORANTE
IPC: H03L7/10
Filed: 1993-02-26
Abstract: PURPOSE: To synchronize a voltage-controlled oscillator VCO with open-loop frequency when frequency is kept within a pull-in range, and to give smooth transition from an open-loop step-up of system frequency to closed-loop PLL operation. CONSTITUTION: An external clocking signal is used until the clocking signal reaches a preset VCO frequency and synchronism with respect to the external clocking signal of an output from a VCO 52 is obtained, and clocked to an internal signal designed which the VCO should follow. Consequently, a smooth transition between an open-loop lamp-up of a polyphase DC motor 19 and a closed-loop operation of loop operation, into which the motor is incorporated, is enabled. Since the circuit phase-synchronizes an output from a PLL loop 40 for phase switching following up the back electromotive force of the motor 19 with an external clocking used for motor ramp-up, no 'oscillation' is generated in the motor in the transition from the open-loop operation of the motor to the closed-loop operation.
