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: In a method of and apparatus for connecting a storage battery to an elevator inverter, the storage battery being connected to a d.c. circuit of the elevator inverter power stage, a voltage in the d.c. circuit is higher than the battery voltage. Power flows bidirectionally from the storage battery to the d.c. circuit and vice versa. When power is flowing from the storage battery to the d.c. circuit, the battery voltage is matched to the voltage in the d.c. circuit by the aid of a semiconductor switch, by means of which an energy store is charged, and a diode, by which the energy in the energy store is discharged into the d.c. circuit. When power is flowing from the d.c. circuit to the storage battery, the voltage of the d.c. circuit is matched to the battery voltage with the aid of a second semiconductor switch, by means of which the energy store is charged, and a second diode, by which the energy in the energy store is discharged into the storage battery.

Abstract: A tachometer is coupled to the rotor of an A.C. motor and generates an output voltage proportional to the rotor's speed. A VELOCITY COMMAND voltage is generated having an amplitude which specifies a desired rotor speed. The tachometer voltage is subtracted from the VELOCITY COMMAND voltage to produce a VELOCITY ERROR voltage. The output of a D.C. power source is chopped at a fixed frequency and variable pulse width, the pulse width being proportional at any time to the amplitude of the VELOCITY ERROR voltage. The chopped D.C. voltage is filtered to provide a variable D.C. voltage having an amplitude which is proportional to the amplitude of the VELOCITY ERROR voltage. The variable D.C. voltage is applied to an inverter which changes it into an A.C. voltage. The A.C. voltage is applied to the stator windings of the motor to drive the rotor thereof. The frequency of the A.C. voltage is variable and is proportional, at rotor speeds above 150 RPM, to the amplitude of the velocity command voltage. At rotor speeds below 150 RPM, the frequency of the A.C. voltage is held fixed at approximately 28 Hz. The amplitude of the A.C. voltage is proportional to the VELOCITY ERROR voltage at all speeds. The frequency of the A.C. voltage is determined by an oscillator which drives a ring counter whose counting direction is controlled by a direction flip-flop. The state of the direction flip-flop is changed whenever the polarity of the VELOCITY ERROR voltage changes so that deceleration of the motor always occurs in a plugging mode.

Abstract: An AC motor is energized by the output voltage of an inverter which in turn receives a DC input voltage from a DC-to-DC converter. A combined oscillator-regulator circuit includes a first potentiometer for adjusting the desired volts/hertz ratio of the inverter output voltage, and a second potentiometer for regulating motor speed. The combined oscillator-regulator receives an output signal from the inverter for comparison against the desired volts/hertz ratio signal, and provides two control signals. The first control signal regulates the operation of the DC-to-DC converter, and the second control signal regulates the frequency of the inverter output voltage.

Abstract: AC motor driving system and driving method thereof are provided. The driving system and method are capable of increasing power factor, adjusting waveform of the DC ripple voltage for increasing driving efficiency. The driving system is basically constructed by connecting three circuits. The first circuit is a three-phase full wave rectifying circuit and is used to transfer commercial electricity to a first DC voltage. Then, the second circuit is used to transfer the first DC voltage to a second DC voltage that ripples voltage thereof having a semi-sinusoidal waveform. The third circuit is an AC driving circuit, and receives the second AC voltage for driving the AC motor. Thereby, the driving efficiency can be increased. The capacitance used in the present disclosure has low capacitance value, thus the power factor can be increased, and usage time of the AC motor driving apparatus can also be increased.
