摘要： A power converter control apparatus comprising continuously controlled converter units and on-off controlled converter units for effecting powering control and regenerative braking control of a DC motor, which is arranged to include a unit change circuit for generating unit changing operation signals in response to a command for instructing the number of the converter units to be rendered operative from a master controllerand conduction phase signals from a phase shifter. In accordance with the unit changing operation signals, the conduction phase signals from the phase shifter are applied as a gate signal to the continuously controlled converter units in response to a powering control or a regenerative braking command, while a minimum conduction phase signal is applied as a gate signal to the on-off controlled converter units in response to a powering control command signal and a maximum conduction phase signal including a commutation marginal angle in response to a regenerative braking command signal. On the other hand, the gate signals supplied to the continuously controlled converter units may be temporarily cut off by a gate cut-off circuit and at the same time the conduction phase in the output of the phase shifter may be restored.

摘要： This invention is applied to a power converter with a converting apparatus comprising one or more units including only controlled rectifiers or combination of controlled rectifiers and non-controlled rectifiers, said converting apparatus being connected with an AC power source, whereby high harmonic currents generated in the AC circuit during commutating periods are reduced.In the present invention, at the commutating period of the converting apparatus, the reactance in the AC circuit of the converter is changed to increase in accordance with change of the AC current of the converting apparatus, so that the change of the AC current during the commutating period is made more slowly thereby reducing high harmonic currents.

摘要： A foamed layer-laminated film or sheet having a foamed layer of a thermoplastic resin laminated on a base material such as a paper or PET, and is useful as a material for producing formed articles such as paper containers, aluminum foil containers, packing films and sheets for containing high-temperature foods, beverages and the like owing to its enhanced heat-insulating property. The foamed layer has innumerable fine elongated foamed cells, and local shades of distribution density of the cells create an appearance of vertical striped patterns on a frosted-glass-like translucent background lending the laminated film or sheet well for use as a material for ornamental articles. The invention further provides a process for easily producing the film or sheet maintaining good productivity at a low cost. The laminated film or sheet includes at least a base material and a thermoplastic foamed resin layer, the foaming layer being foamed at the time of extruding a thermoplastic resin composition containing a foaming agent so as to be laminated on the base material.

摘要： A DC voltage on an electric car stringing is supplied to a variable voltage and variable frequency PWM inverter so as to be converted into a three-phase alternating current which is supplied to a plurality of three-phase induction motors. The motors are connected to different wheels to drive an electric car. The inverter is controlled on the basis of an operating frequency command determined by adding or subtracting a slip frequency command to or from a motor speed and a voltage command proportional to the operating frequency command. On the other hand, a motor current command is set and compared with a maximum current value of currents of the plurality of motors, and the slip frequency command is corrected in accordance with a difference therebetween. In a constant torque region of the electric car, a correction value increasing in proportion to the speed is then added to the motor current command, so that torque of motors other than a motor to which the maximum current flows compensates for a decrease in torque caused as the speed increases to improve constant torque characteristics.
