摘要： PURPOSE:To precisely control the speed of a linear synchronous motor by employing a position signal of frequency substantially equal to the speed of the motor and a frequency pattern corresponding to the speed pattern of a vehicle in phase difference. CONSTITUTION:A frequency pattern 22 corresponding to the speed pattern of a vehicle is generated from a frequency pattern generator 21. The phase difference between the frequency pattern 22 and the position signal 4 is detected by a phase difference detector 23. A phase difference compensating unit 25 is accelerated or decelerated in the current peak value 26 in response to the detected phase difference 24. The value 26 is applied to a current limiter 14 to form a current peak value pattern 15. Subsequently, a current waveform pattern 20 and a current peak value pattern 15 are multiplied by a multiplier 16 to produce a current pattern 5. The armature coil current 10 detected by a current detector 9 is compared with the current pattern 5 by a comparator 6, a power converter 8 is so controlled that the compared output becomes low. Thus, the speed of the motor is precisely controlled.

摘要： PURPOSE:To readily open a changeover switch by controlling the output current of a cycloconverter to small AC current when the section of a linear motor is switched. CONSTITUTION:3-phase armature coils SECn-1-SECn+3 are supplied with 3- phase sinusoidal currents from cycloconverters CC-A, CC-B through 3-phase switches SWn-1-SWn+3 controlled by a section switching controller SC. When analog switches ASA, ASB are closed at the side by signals G1, G2 from the controller SC, and when the normal 3-phase sinusoidal current command is closed at b side, 3-phase small current command is applied to the cycloconverters CC-A, CC-B. The opening and closing of the switches SWn-1-SWn+3 are executed when the cycloconverters CC-A, CC-B are controlled by 3-phase small current.

摘要： PURPOSE:To suppress the variation in the reactive power produced due to the breakage of a gate by gradually falling or rising the output current and a circulating current when switching a cycloconverter from energized state to a gate interrupting state, from gate interrupting state to energized state. CONSTITUTION:When a train VH enters a section SECn, a signal G1 becomes 0 by a section switching controller SC, and the output signal F11 of the primary delay circuit H1 (S) gradually decreass. Thus, a load current command value LLA* of a cycloconverter CC-A and a circulating current command value IOA* are attenuated. Therefore, the entire reactive power QT advances, and the circulating current command IOB* of the cycloconverter CC-B increases. When the 3-phase load current ILA of the cycloconverter CC-A and the current IOA become sufficiently small, the output signal G12 of a Schmitt circuit SH1 becomes 0, and the gate of the cycloconverter CC-A is not interrupted at the gate.

CONSTITUTION:The position signal 5(n) and thrust command 22(n) of a train are delivered from a power conversion station(n) driving the car to the power conversion station(n+1) of a feeder section 1(n+1) where the train is to go. Then, the position signal 5(n) of the train is inputted to a state detector 11(n+1) to detect the acceleration 27(n+1), speed 26(n+1) and phase 25(n+1) of the train. Thereafter, the acceleration 27(n+1) is set via switch SW3(n+1) to an integrator 33(n+1) generating an acceleration pattern 30(n+1). The speed 26(n+1) is set via switch SW4(n+1) to an integrator 34(n+1) and integrator of APR 36(n+1) generating a speed pattern 29(n+1).

摘要： PURPOSE:To eliminate a thrust pulsation when a vehicle crosses over adjacent propulsion coil zones by transmitting a position detection signal and a thrust command signal from a drive controller for controlling to drive the vehicle to a drive controller for controlling to next drive the vehicle. CONSTITUTION:When a forward vehicle is moved out of a propulsion coil 63 to reset an existing line detection signal 88 in the state that a vehicle 64 is driven by a propulsion coil 62, switches 46, 54, 55, 56 are closed at their side (a). Thus, the position detection signal 96 of the vehicle 64 driven by a drive controller (n) and a thrust command 10 of the controller (n) are fed to a drive controller n+1. when the vehicle 64 enters the zone of the (n+1)-th coil 63, the signal 88 is set, and the switches 46, 54, 55, 56 are closed at their side (b). Thus, the controller n+1 outputs a thrust command 40 on the basis of a phase detection signal 97 to control to drive the vehicle 64.

摘要： PURPOSE:To output a speed proportional signal accurately followed by the variation of the speed of a moving unit by employing a phase difference at every prescribed distance period to operate a phase correcting unit at the period of integer times and determining the correction output so that the phase difference at the next correcting time point reduces. CONSTITUTION:A speed calculator 3 calculates a speed TLi by a moving unit position signal at every prescribed distance, and stores it in a register 9. On the other hand, a phase difference input unit 7 inputs a position difference Tp at every prescribed period, writes it in a phase difference register 8, and applies the content of the register 8 to a phase correcting unit 4 at every integer time of the phase difference inputting period. The unit 4 calculates a correction value K from two phase differences Tpi, Tpi-1. When the content TLi of the register 9 is lower than the set value, the speed Ti after correction is calculated by TLi+K, while when higher than the set value, the speed Ti-1 after the previous correction is used, and the speed Ti after the correction is calculated by Ti-1+K.

摘要： PURPOSE:To remove the side wave near a power frequency by connecting an another converter with the same AC power source as a power converter, and controlling the converter with a signal representing the side wave generated by the converter as a command value. CONSTITUTION:In a device for supplying a power to a load by connecting a power converter CCU connected in anti-parallel with positive and negative side converters SSp, SSN with an AC power source SS, an another converter CN is connected with the power source SS. The converter CN is controlled by a signal representing a side wave generated from the converter CCU as a current command. To this end, the sum of a circulating current command value Icp and a DC command 2 is calculated by an adder 4, and the value produced by subtracting the output by a subtractor 5 by the rectified and amplified output of the AC input current Is is used as a current command value to control the converter CN.
