Abstract: On end of a reactor (L1) is connected to a positive electrode of a battery (B1) and the other end is connected to a power line via a transistor (Q1) and to the ground via a transistor (Q2). By PWM control of the transistors (Q1, Q2), an arbitrary increased voltage is obtained in the power line. It is possible to obtain an optimal inverter input voltage (power line voltage) according to the motor drive state, thereby increasing efficiency. Thus, it is possible to optimize the inverter input voltage according to the motor drive condition.

The power supply device includes an inrush protection (IP) circuit, a power factor correction (PFC) circuit and an overvoltage protection (OP) circuit. A controller and a pair of relays selectively connect predetermined components so that at least one component is selectively changed from operation in one of the IP, PFC and OP circuits to operation in another of the IP, PFC and OP circuits in response to a detected value of an inverter input voltage. The inrush protection circuit operates in a start up mode; the PFC circuit operates while normally driving the motor; and the overvoltage protection circuit operates where the inverter input voltage increases due to regeneration by the motor.

Abstract: A motor control system for controlling power supplied to an electric motor rotating a rotor employed in a centrifuge is provided. The motor control system includes first, second, and third converters and first and second smoothing capacitors. In a motor power mode, the first converter operates to transfer the charged energy in the first smoothing capacitor to the second smoothing capacitor for providing power to the motor through the third converter, while the second converter transfers, in a motor braking mode, the charged energy in the second smoothing capacitor to the first smoothing capacitor to return the power regenerated by the motor during a braking operation to the AC power supply through the first converter. The second converter performs a function of providing an initial energizing energy to the motor for a given period of time at the start of the braking operation for stability of a power-regenerating operation of the motor.

Abstract: It is an object of the invention to provide a transistorized full-bridge driving circuit for an electronically commutated collectorless dc motor, in which burnout of the pnp transistors from overvoltage is avoided. This is accomplished by an arrangement with a collectorless dc motor (19) commutated by a semiconductor circuit, with a rectified-current intermediate circuit (13,14) supplied via a rectifier (11) from an AC current network, the intermediate circuit having an input to which is applied a fluctuating rectified current with predetermined maximum values, with a transistor (12, 112) located between the rectifier and the collectorless dc motor, the transistor being driven as a variable resistor, and with limiting means (25-27), for limiting the voltage at the control input of this transistor (12, 112) to a value smaller than the predetermined maximal value of the fluctuating rectified voltage and which control voltage falls within the voltage-tolerance range of the semiconductor driving circuit of the collectorless dc motor. The use of the limiting means, in combination with the transistor operated as a variable resistor, limits the voltage in the rectified-current intermediate circuit to an upper value, e.g. 270 V, so that standard commercial pnp- and npn-transistors can be used for the semiconductor driving circuit for commutation of the collectorless dc motor, and in this manner the semiconductor circuit is protected from overvoltage conditions. In the transistor which is driven as a variable resistor, corresponding losses do arise, but one avoids losses which would otherwise occur in a corresponding low-voltage power supply, so that overall a very good operating level results.
