摘要： A sine wave of a frequency to be generated in an inverter is compared with a triangular wave having a frequency N times (N: 15, 9, 3, 1) the frequency of the sine wave, so that a modulated pulse train is generated thereby to control the inverter. This inverter supplies power to an induction motor. With the increase in motor speed, N is reduced until it finally becomes 1. When the inverter transfers from an idle state to an active state, N is inhibited from becoming 1 but set to 3 even if the motor is running at high speed.

摘要： A power converter such as an inverter or chopper using self-turn-off type semiconductor devices supplies power to an inductive load and free wheel diodes are provided so that the current flowing through this load circulates not through the power supply but through the free wheel diodes. When it is detected that the load current exceeds a predetermined value, the self-turn-off-type semiconductors which are conductive are turned off. At this time, the self-turn-off-type semiconductors which are turned on and immediately thereafter cause the recovery current to flow in the free wheel diodes are turned off not immediately but after the recovery current disappears.

Here, a motor rotation frequency/phase detection circuit of each inverter control circuit is set up on a closer side to the motor than the breakers, then frequency and phase of a terminal voltage at the motor are detected and inputted into failure-time input frequency/phase setting circuits regardless of close/open of each breaker. This feature allows computation by the failure-time input frequency/phase setting circuits to be carried out at all times, thereby making it possible to shorten a computation time needed for computing inverter-apparatus start frequency/phase.

摘要： A DC voltage on an electric car stringing is supplied to a variable voltage and variable frequency PWM inverter so as to be converted into a three-phase alternating current which is supplied to a plurality of three-phase induction motors. The motors are connected to different wheels to drive an electric car. The inverter is controlled on the basis of an operating frequency command determined by adding or subtracting a slip frequency command to or from a motor speed and a voltage command proportional to the operating frequency command. On the other hand, a motor current command is set and compared with a maximum current value of currents of the plurality of motors, and the slip frequency command is corrected in accordance with a difference therebetween. In a constant torque region of the electric car, a correction value increasing in proportion to the speed is then added to the motor current command, so that torque of motors other than a motor to which the maximum current flows compensates for a decrease in torque caused as the speed increases to improve constant torque characteristics.
