摘要： A magnetic phase shifter utilizing the principle of magnetic amplifier is used as a phase shifter for applying a firing signal to a main thyristor. In order to amplify and sharpen the rise of the output pulse of the magnetic phase shifter, an auxiliary thyristor is fired by the output pulse of the magnetic phase shifter. The gate-cathode circuit of the main thyristor is connected to the auxiliary thyristor as a load thereof. Power for the auxiliary thyristor is obtained from an AC power supply which is in phase with the main thyristor through a transformer, while power for the magnetic phase shifter is introduced from an intermediate tap of the secondary winding of the transformer, thus making the magnetic phase shifter compact as well as low in cost.

摘要： In a controller for an AC elevator in which the frequency of AC power applied to a driving induction motor is varied by a frequency converter, the output frequency of the frequency converter when the elevator is running at its rated speed is at least as high as the frequency of the AC supply, and the AC supply is applied directly onto the induction motor without any frequency conversion during low-speed running, so that the elevator can be run slowly without using the frequency converter.

摘要： In an a-c elevator, an elevator car suspended by ropes is driven by an induction motor for vertical movement. A system commonly used for controlling the device including thyristors connected in parallel with opposite polarities across a three-phase a-c power source and the induction motor for controlling the motoring torque produced by the induction motor, a bridge rectifier including a thyristor for supplying direct current to the induction motor for controlling the braking torque produced by the induction motor, and means for controlling the operating phase of the thyristors in the thyristor device and the thyristor in the bridge rectifier depending on the error between the instructed speed and the actual speed of the elevator car. When the elevator car stops at a target floor and passengers get on and off the elevator car, the variation in the load of the elevator car results in an increase or decrease in the length of the ropes thereby giving rise to an error between the floor level of the target floor and that of the elevator car. A levelling apparatus is provided which comprises a position detector detecting this level error in either direction, and a level correction speed pattern signal generator generating a level correction speed pattern signal in response to the appearance of an output from the position detector, so that the operating phase of the thyristors in the thyristor device and the thyristor in the bridge rectifier can be controlled depending on the error between the level correction speed pattern and the actual speed of the elevator car.

摘要： A control system for an AC elevator system in which an actual speed of an elevator car is compared with a speed command and control is made so that deviation between the actual speed and the commanded speed becomes zero. The speed command is so composed that deceleration of the elevator car is gradually decreased as the car approaches to a target landing position in the stopping operation of the elevator. A motoring torque or a braking torque is additionally generated in dependence on a load on the car in a region close to the target landing position.

摘要： In a three phase load controlling system two bilateral switching circuits control the current in the first and the third phases; the first phase is later than the third. The second phase is uncontrolled. The gating signals applied to the bilateral switching arrangement connected in the first phase are advanced by a constant degree with respect to the voltage of the first phase. The gating signals applied to the bilateral switching arrangement connected in the third phase are synchronized with the voltage of the third phase.
