Title: Control of brushless motor
Inventor: MORI TOMOYUKI
IPC: H02P6/18
Filed: 1996-04-18
Abstract: PROBLEM TO BE SOLVED: To prevent reverse current from appearing in switching a chopping of an upper and a lower arm when controlling the rotation of a brushless motor. SOLUTION: AC of an AC power supply 1 is rectified by a voltage doubler rectifier circuit 2 into DC of double voltage, which is supplied to armature windings of a brushless motor 4 through a transistor module section 3. In this case, a controlling circuit 10 detects the position of a rotor 4a, based on a position signal from a position detecting section 5. Based on the detection result, transistors U, V, W of an upper arm and transistors X, Y, Z of a lower arm of a transistor module section 3 are on/off-controlled. One of the arms is chopped and then a chopping of the arms is switched wit a given timing. At this point, the termination of spike voltage appearing in the armature windings of the burshless motor 4 is detected by the position signal from the position detecting section 5.  After the detection of the termination of the spike voltage or when the passage of a given electric angle after the former position detection is behind the termination of the spike voltage, a chopping of the upper and the lower arm is switched after the passage of a given electric angle.

Filed: 1978-10-02
Abstract: PURPOSE: To prevent picture quality deterioration of receiving signals by switching continuously or discontinuously the gain of a PLL for phase fluctuation based on the transmission line and improving a response property.  
     CONSTITUTION: PLL4 is constituted by voltage control oscillator 14, phase difference detection circuit 9, LPF10, FET13, etc. Then, the phase difference between receiving signals inputted to circuit 9 and oscillator 14 is inputted to LPF10. The output of comparator 11 is inputted to FET13 through charge/discharge circuit 15 and inversion circuit 12 to control the input current passing through LPF10 and send the output of oscillator 14 to a synchronizing detector. Since FET13 operates as a variable resistance element in this circuit, the gain of oscillator 14 can be changed continuously. Consequently, the output of LPF10 is monitored; and when this output is fluctuated greatly, the gain of loop 4 is switched, that is, the sensitivity of oscillator 14 is enhanced, thereby improving the following property of loop 4. By this constitution, the following property of loop 4 is improved for phase jump or phase jitter generation, so that the picture quality can be prevented from being deteriorated.
