    摘要： An electrical power converter having a phase converter constituted by positive side semiconductor switching elements connected in series and negative side semiconductor switching elements connected in series which converts a DC voltage to an AC output phase voltage having at least three potential levels, resulting in three possible modulation modes: dipolar, partial dipolar and unipolar. Dipolar modulation is realized by alternating positive and negative output pulses. Unipolar modulation is realized by output pulses having only the same polarity as the corresponding fundamental modulation wave. Transition is accomplished via partial dipolar modulation which is realized by alternating positive and negative output pulses in a first period of a half cycle by outputting alternating positive and negative pulses and in a second period by outputting pulses having only the same polarity as the corresponding fundamental modulation wave. A control unit for the converter turns the semiconductor switching elements on and off depending on an input voltage amplitude command for a fundamental modulation wave. The intervals of the first and second periods in the half cycle of the AC output phase voltage varies dependent upon the voltage amplitude command.

    摘要： In a control apparatus of an induction motor including an inverter for converting a direct current to an alternating current having a variable voltage and variable frequency in accordance with a pulse width modulation control, and a controller for controlling an output voltage of said inverter through a modulation rate which is requested in accordance with an exciting magnetic current component command in a primary current of the induction motor driven by said inverter and a voltage component command corresponding to said respective components which are executed in accordance with a torque current component command, the control apparatus of the induction motor operates to detect a torque current component in accordance with said primary current of the induction motor, to correct said torque current component from a deviation between said detected torque current component value and said command value, to correct an output frequency of said inverter in accordance with said corrected torque current component command, and to limit the size of the modulation rate to less than a predetermined value or less than a predetermined condition. With this construction, in the induction motor, without the change-over from the low speed area to the high speed area (PWM pulse mode is 1 pulse area) where the size of the voltage command exceeds the maximum voltage capable of being output by the inverter, which is determined according to the direct current voltage, a good vector control can be carried out.

    摘要： In a pulse width modulation control method and system for an electric power converter, in order to suppress the occurrence of lower order harmonics and fractional order harmonics in a direct current component even in a condition where a carrier frequency is several times as small as the frequency of a command value, pulse width modulation pulses for driving semiconductor elements in the electric converter are calculated by comparing a command signal from a command value generating means with a carrier signal having a continuous triangular-wave and a constant period. For this purpose, there is provided a means for separately calculating a time product of a command value of the command signal from the command value generating means and a time product of the pulse width modulation pulses and for calculating a difference value representing a difference between both time products. The pulse width modulation pulse is then calculated using the calculated difference value to compensate the command signal received from the command value generating means.
