    Abstract: An apparatus for providing a polyphase alternating current including a pulse generator and a digital counter for converting the pulses into a predetermined number of distinct consecutive signals which are cyclically applied to a decoding circuit for each phase, each having one output line per signal. A digital to analog converter connected to each decoding circuit designates a voltage level to each consecutive signal which is proportional to the sine of the phase angle during which the signal occurs.

    Abstract: A commutation control circuit for a motor including a power thyristor and an auxiliary thyristor for switching the power thyristor under control of a variable frequency pulse generator making use of a capacitor for commutation charged by a transformer, the charge on the capacitor being established to be ready for commutation whenever the power thyristor is gated, and the charging current being derived from a direct current source such as a lead/acid storage battery. The circuit specifically uses a positive pulse for causing conduction of the power thyristor and a negative pulse for switching the power thyristor ''''off.

    Abstract: A control circuit for regulating the speed of a polyphase induction motor by changing the frequency and voltage level of the supply source supplying power to the motor. The difference between a speed reference signal and an output signal from a closed loop feedback circuit is converted to a sine wave alternating current signal having a frequency which varies with the time integral of the difference. A circuit for amplifying this alternating current signal provides power to the induction motor. A pair of diodes connected in the feedback circuit limits the rate of change of the frequency of the alternating current signal to a value determined by the design of the motor. The voltage amplitude of the alternating current supplied to the motor is adjusted as a function of the frequency and is further adjusted as a function of slip of the motor. Additional adjustment of the volts/cycle/second value of the alternating current supplied to the motor allows for overexcitation of the motor even beyond the design limits of the motor in order to provide the greatest possible torque to maximize the rate of change in speed and direction of the motor.
