Abstract: A power control apparatus for controlling power supplied to an electric motor rotating a rotor employed in a centrifuge is provided. The power control apparatus includes first and second inverters and a smoothing capacitor disposed between the first and second inverters. In a motor power mode, the first inverter charges the smoothing capacitor with power supplied by an AC power supply, while the second inverter charges, in a motor braking mode, the smoothing capacitor with power regenerated by the motor during a braking operation for returning the regenerated power back to the AC power supply through the first inverter. An reactor is arranged between the AC power supply and the first inverter for reducing harmonic components contained in the current supplied from or back to the AC power supply.

Abstract: A semi-conductor system for controlling three phase motors by voltage and/or frequency variations. An input circuit provides dc power, such as a three phase full wave input bridge with silicon control rectifiers to provide a voltage controlled dc power output. An output inverter bridge having six silicon rectifiers receives dc power and converts it to three phase ac power for operating an induction motor. A diverter network is connected between the dc power input circuit and the output inverter and is activated periodically for temporarily diverting the dc power from the inverter in order that the inverter rectifiers may be turned off. The diverter may include a tank circuit having a capacitor and an inductor connected across the dc power output through a diode and a silicon control rectifier is connected to the tank circuit for shunting the dc power from the inverter and applying a reverse voltage to the inverter. A harmonic suppression circuit is connected across the output of the converter and may include a capacitor connected between each of the three phase output lines of the inverter.

Abstract: A variable speed induction motor control system includes a variable voltage DC bridge coupled to a frequency controlled power inverter which in turn drives an induction motor. A motor power factor detecting circuit determines the relative voltage/current phase angle for the motor and derives a corresponding power factor error signal. The DC bridge and inverter respond to the power factor error signal to maintain the input power conditions of the motor at a near optimum efficiency. The power factor detecting circuit uses an exclusive OR gate to provide a pulse having a duration corresponding to the motor power factor which enables a counter during the pulse interval. After each pulse, the count which is indicative of the motor power factor, is applied to a holding circuit and converted to an analog error voltage.

Abstract: In a variable frequency power converter of a current type for driving an AC motor including a rectifier, an inverter, and a smoothing reactor disposed on a DC transmission line between the rectifier and the inverter, there are provided a series circuit having a switching circuit and a smoothing capacitor on the DC input side of the inverter and a feedback circuit having controlled rectifier elements and commutation reactors for feeding back the reactive power of the AC motor. The power converter operates as a current type converter until the output frequency of the converter reaches a predetermined value under the condition that the switching circuit and the controlled rectifier elements are non-conductive, and operates as a voltage type converter when the output frequency has reached the predetermined value under the condition that the switching circuit and the controlled rectifier elements are conductive.

Abstract: THE SPEED OF AN AC MOTOR CAN BE CONTROLLED BY VARYING THE INPUT FREQUENCY AND VOLTAGE SUPPLIED TO THE MOTOR. THE INVENTION IS CHARACTERIZED BY A SOLID-STATE SWITCH BRIDGE CONNECTED TO THE ELECTRIC MOTOR FOR SUPPLYING GENERALLY SQUARE WAVE VOLTAGE PULSES TO THE MOTOR AT THE DESIRED FREQUENCY. THE SQUARE VOLTAGE PULSES ARE CHOPPED TO ADJUST THE AVERAGE VOLTAGE SUPPLIED TO THE MOTOR TO MAINTAIN THE CONSTANT TORQUE CHARACTERISTIC REQUIRED FOR THE INPUT FREQUENCY TO THE MOTOR. AN RC ATTENUATING CIRCUIT IS CONNECTED TO THE MOTOR IN SUCH A WAY THAT WHEN THE FREQUENCY IS CHANGED THE REGULATED LEVEL OF THE AVERAGE MOTOR VOLTAGE IS AUTOMATICALLY CHANGED TO A VALUE WHICH MAINTAINS THE TORQUE IN THE MOTOR SUBSTANTIALLY CONSTANT.
