Abstract: An inverter supply voltage generator comprises an inverter supply voltage computing unit 10, a voltage converter 11 and a battery 12. The inverter supply voltage generator varies inverter supply voltage Vdc in synchronization with motor-application voltages Vu_pwm, Vv_pwm, and Vw_pwm. Thus, the degree of freedom of the switching operation of a PWM inverter 13 is increased, an inverter loss and the size of the PWM inverter 13 can be reduced, and its efficiency can be enhanced without deteriorating the driving efficiency of an IPM motor 14.

Abstract: The present invention is directed to a method and apparatus for connecting a static inverter to a free-running motor, wherein the inverter is supplied with D.C. power by a regulator-controlled rectifier. An oscillator connected to both the rectifier regulator and the inverter governs the frequency of the three-phase inverter output, while voltage feedback from the inverter output to the rectifier regulator is employed to establish a proper volts/hertz output characteristic in the inverter output waveform. During the connection process, a synchronizing circuit causes the oscillator to generate a high pulse rate signal which raises the inverter output frequency to a level above that associated with the rotational speed of the free-running motor. Simultaneously, the D.C. output of the rectifier is clamped by the current regulator to current-limit the inverter output. The inverter is subsequently connected to the free-running motor and the inverter output frequency is allowed to decrease gradually. When the frequency of the inverter output equal the rotational speed of the motor, the motor impedance increases substantially to create a voltage rise in the inverter output, followed by phase equalization between the inverter output and the back e.m.f. of the motor. In this manner, smooth, synchronous connection of the inverter to the rotating motor is achieved.

Abstract: The invention relates to an inverter circuit for operating a speed-controllable asynchronous motor. The inverter circuit is of the type wherein the voltage and frequency are substantially proportional until the nominal frequency has been reached at nominal voltage. The circuit includes and inverter, a desired value control, a D.C. voltage supply with a voltage regulator which sets the voltage depending on the desired value, and a voltage-operated frequency regulator. The circuit can be operated at frequencies above the nominal frequency to avoid damage to the inverter which would otherwise be caused by (1) high voltage due to the motor operating as a generator or by (2) the rapid reduction of the speed setting controls which is not accompanied by a corresponding drop in the voltage supplied to the inverter.

Abstract: A circuit to dampen oscillations occurring in rotating field machines such as low friction hysteresis motor drives is disclosed. The circuit operates by detecting the frequency of oscillations occurring in the machines and regulating the frequency of the power fed to the motors to dampen the oscillations. The damping is produced by using a bandpass filter tuned to the frequency of the oscillations and subtracting this frequency from a predetermined frequency to thereby force the rotating stator field of the machines to track the oscillations of the machine''s rotors.
