摘要： PURPOSE:To eliminate the variation in the torque at pulse number switching time by performing the switching of the number of pulses at the time point when the phases of the carrier signals coincide with each other. CONSTITUTION:The primary voltage of alpha-beta shaft calculated by a noninterference calculator 6 which inputs the alpha-shaft primary current set value and the beta- shaft primary current command is converted by a coordinates converter 7 into polar coordinates data, and input to a PWM waveform calculator 8. PWM pattern data is applied from a pulse pattern generator 10 and a pattern data converter 11 to the calculator 8, and the conversion of the number of the carrier pulses is executed in the phase coincident with the carrier pulse peak phase before and after the conversion. A gate circuit 9 obtains a PWM waveform of the actual phase inverter voltage in accordance with the data from the calculator 8, and the switching element of the inverter 1 is controlled ON or OFF in accordance with the voltage.

摘要： PURPOSE:To optimize the controllability of a converter by providing a means varying the gains of a converter control system in response to the state of operation of an inverter. CONSTITUTION:Electromagnetic switches 241-24n are each mounted to DC paths to n inverters 221-22n from a converter 21, and the switches are ON-OFF cotrolled in response to the commands of the inverters of operation or stoppage by an operation sequence circuit 25. The sequence circuit 25 is provided with a control means changing over and controlling the gains of a voltage control amplifier incorporated into a control circuit 21A for the converter 21 at the same time as the ON-OFF control of the switches 241-24n. Accordingly, even when capacitor capacity viewed from the converter 21 alters in the separation or juxtaposition of DC side capacitors for the inverters 22, the gains of a converter control system are controlled automatically, thus eliminating trouble on operation due to the transient characteristics of the converter.

摘要： PURPOSE:To obtain a highly universal inverter controlling circuit which can control both the output pulse width and the pulse frequency by combining a variable frequency pulse generator, a variable pulse width controlling circuit, a frequency divider and a logic circuit. CONSTITUTION:A voltage/frequency converter 3 outputs a pulse of the frequency responsive to the set frequency voltage from a terminal 2, and a pulse width controlling circuit 4 controls the width of the pulse from a converter 3 in response to the set width voltage from a terminal 1. A frequency divider 5 divides the input pulse into 1/2 frequency, and the output from the divider 5 is inputted through OR circuits 6, 10 (and one through an inverter 9) to ones of AND circuits 8, 11. Signals corresponding to the ON zone of a pair of thyristors of an inverter (not shown) are applied to the other terminals 7 of and AND circuits, which in turn produces control signals P7, P8 to the respective thyristors.
