Title: Sinusoidal wave drive thyristor motor
Inventor: SAITOU KEIJI
IPC: H02P25/02
Filed: 1983-06-27
Abstract: PURPOSE:To improve the speed responding characteristic by operating in the prescribed range of delay power factor, thereby reducing a rotor side necessary magnetomotive force and reducing the inertia. CONSTITUTION:A frequency converter 2 is energized by a power transformer 1. The converter 2 produces sinusoidal wave 3-phase AC voltage of necessary voltage and frequency, and applies it to a synchronous machine 3. The position of a rotor is continuously detected by a distributor 4. A controller 9 receives a signal of the distributor 4, and controls the converter 2 so as to become voltage, current and frequency necessary for the machine 3. A field winding 5 is excited by a variable voltage DC power source 7. The machine 3 is controlled to become not the power factor 1.0 but 0.85 at the least in the delay power factor.
Patent JP-H10295072-A (JP)
Title: Semiconductor power converter
Inventor: MORI KAZUHISA
IPC: H02H7/12
Filed: 1997-04-16
Abstract: PROBLEM TO BE SOLVED: To stably supply electric power to the gate drive circuit of a self-arc- extinguishing type switching element by installing a circuit having a capacitor for power-supply, which is charged at each switching operation of the self-arc- extinguishing type switching element and which functions so as to suppress a voltage to a certain range. SOLUTION: When a power supply voltage is raised, a voltage is applied to a self-arc-extinguishing type switching element (GTO) 1, and a capacitor 6 for power supply is charged by the voltage. When the GTO 1 is turned on, an electric charge which is stored in a snubber capacitor 2 is discharged, and the capacitor 6 for power supply is charged. When a switching element 10 is turned on in this state, the charging operation of the capacitor is stopped, and a voltage rise is suppressed. When the GTO 1 is turned off, a current flows to the snubber capacitor 2 and a snubber diode 3, and the switching element 10 is turned off. At this time, the snubber capacitor 2 is overcharged, and when it is discharged, the capacitor 6 for power supply is charged thereafter. As a result, stable supply of the electric power is made to a gate drive circuit 9.

Abstract: PURPOSE: To improve fin inserting ability and reduce working time by controlling a motor in cooperation to difference the rotating angle of the motor having been measured with a measuring device and the preset value.  
     CONSTITUTION: When a start signal is applied, a start signal generator 44 sends a signal to a rotating number selector 51. The rotating number selector 51 sends the contents of a preset rotating number register 45 to a D/A converter 52, then a servo motor 16 runs at the assigned speed. On the other hand, a subtractor 55 creates the difference between the data of the rotating angle register 48 and the data of an encoder 32 and sends the same to the data selector 51. When the difference becomes 0, the data are changed over to the preset rotating number register 46 and are sent to a D/A converter 52. In this way, the fins are inserted by ideally accelerating and decelerating the fin feed mechanism. The start signal generator 44 sends the start signal to the data selector 35 of the travelling motor 27 upon receiving of the revolution end signal of the encoder 32, thereby ideally shifting the insertion unit through acceleration and deceleration.
