    Abstract: In the hybrid vehicle, a boost converter is controlled to make a post-boost voltage or a voltage on the side of an inverter become a target post-boost voltage corresponding to a target operation point of a motor in accordance with a target post-boost voltage setting map that divides an operation region of the motor into a non-boost region and a boost region when a operation point of the motor is included in the boost region. The target post-boost voltage setting map is prepared so that the non-boost region includes a region in which a loss produced by driving the motor when not boosting the post-boost voltages becomes smaller than the loss produced when boosting the post-boost voltage and the boost region includes a region in which the loss produced when boosting the post-boost voltage becomes smaller than the loss produced when not boosting the post-boost voltage.

    Abstract: A motor control apparatus for a sewing machine includes an adjustable speed setter for generating a speed set signal. A first memory stores a plurality of reference values each defining a reference region into which the speed set signal can fall. A second memory stores speed setpoint values corresponding to the reference regions. A central processing unit selects one of the reference regions by comparing the speed set signal with the reference values and selects the corresponding speed setpoint value from the second memory. A motor is controlled to run at the selected speed setpoint value.

    Abstract: A reactive power processing circuit for a current source GTO invertor in which a reactive current generated from a load of the GTO invertor is rectified by means of a fly wheel circuit and is sent to a capacitor so as to store a commutation surge voltage generated whenever a commutation of the invertor occurs, an excessive charge voltage across the capacitor is regenerated to a direct current output side of a power rectifier, and a pair of GTO (Gate Turn Off Thyristors) thyristors are connected between the capacitor and the direct current output side of the power rectifier in their forward directions so as to carry out a discharge operation for the excessive charge voltage across the capacitor. Consequently, with the number of circuit elements remarkably reduced, the reactive power processing at times of a high-frequency operation and acceleration/deceleration (variable speed) operation of the invertor can be achieved.

    Abstract: Stabilized operation of an inverter and an a-c motor, driven by the inverter, is obtained in the presence of sudden undesired load changes by controlling the inverter so that both the amplitude and frequency of the inverter output a-c voltage will be functions of, and will vary directly with, the d-c bus voltage, with the result that anytime an abrupt abnormal load change causes the d-c bus voltage to vary, a frequency change occurs to compensate for the load change and to stabilize the bus voltage. By employing the d-c bus voltage to regulate the inverter frequency, if there is a sudden decrease, for example, in the mechanical load on the motor, the d-c bus voltage, which will tend to increase, causes the frequency of the inverter output voltage to increase, thereby increasing the motor speed so that the electrical load change across the d-c bus is reduced. As a result, the d-c bus voltage tends to remain relatively constant in spite of the abrupt mechanical load change. When there is a normal variation in load demand, necessitating a different steady state motor speed, a set point or reference voltage may be adjusted to change the amplitude and frequency of the inverter output voltage to the levels needed to drive the motor at the new required speed.
