    摘要： AC induction motor energized by an inverter coupled with a DC power source. Upon shutdown of the inverter because of a fault condition or a rail gap between adjacent power sources, if the motor rotating frequency is greater than a minimum frequency then a decreased motor voltage is applied to the motor and increased as a ramp over a provided time delay period, after which the motor slip is controlled to provide a desired motor torque that is increased over a subsequent time delay period.

    摘要： A control apparatus and method are provided for a load energized by an inverter coupled with a DC power source. The lag current angle between the current and the load voltage is utilized to determine when the output current is positive and when the output current is negative. The conduction times of the respective upper and lower gate turn off thyristors of each pole of the inverter are controlled in relation to the established current angle, with a provided modification of those conduction times being phased out in response to the desired output voltage for said load.

    摘要： An arrangement of interconnected timers is provided for operation with a microprocessor programmed to determine time delay counts that are fed out to these timers such that the timers can take care of the actual task of firing GTO inverter switches or not firing GTO inverter switches coupled with an AC traction motor for a vehicle. It is necessary to have correct transitions between the minus GTO switch and the plus GTO switch being ON for providing the desired motor voltage conditions with minimum electromagnetic interference in relation to the power supply. In addition the use of timer queues in complicated synthesis modes like the PWM and the quasi six-step operates to give the microprocessor adequate operating time for reasonable control signal time duration calculations. The timers are synchronized in hardware by a single crystal frequency, and they are synchronized in software such that the three phase independent waveforms stay 120.degree. apart.

    摘要： An active harmonic filter selectively sources current to or draws current from power lines. The active harmonic filter includes a controller which executes a predictor routine which predicts the current to be supplied to or drawn from the power line at a time t+.DELTA.t to reduce load induced phase differences between the line voltage and the line current. An integrating slow control routine integrates difference currents between actual line currents and desired line currents in equivalent segments of time in different cycles of the power line. The integrated differences may be combined with proportionally controlled difference currents to reduce or eliminate harmonic line currents. A current balancing routine enables the active harmonic filter to balance currents in two or more lines of a polyphase power line. The predictor, integrating slow control and current balancing routines, may be used singly or in combination to improve the condition of line currents on the power lines.
