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： The two secondary windings of a transformer the primary winding of which is connected to an AC power supply are each provided with a controlled rectifying circuit. The DC sides of the rectifying circuits are connected in series to supply power to DC motors. One of the secondary windings is detachably connected with a capacitor bank. The capacity of the capacitor bank is selected so that the power factor of the converter can be improved to a satisfactory value when the two rectifying circuits are both controlled to produce output voltages. The capacitor bank becomes connected in response to the fact that the current in the primary winding of a transformer has arrived at a predetermined value.

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： A power converter system comprises a connection of a plurality of controlled rectifiers and a plurality of uncontrolled rectifiers, or a connection of only a plurality of controlled rectifiers. With an AC power supply as an input, the firing phase of the controlled rectifiers is controlled for conversion into a desired power. The commutating operation of the rectifiers is performed by utilizing the AC power supply. A retardation coil is connected to each of the rectifiers connected in series in the same polarity and making up an arm of the connection. The thus connected retardation coils are magnetically coupled with each other. The inductance of the commutating circuit is smaller when the output of the power converter is substantially maximum or minimum than the inductance when the output of the system is not maximum or minimum, thereby effectively reducing the higher harmonics components of the AC input current of the system at the time of commutating operation of the rectifiers without reduction of the utility of the converter.
