摘要： A power converter that interfaces a motor requiring variable voltage/frequency to a supply network providing a nominally fixed voltage/frequency includes a first rectifier/inverter connected to a stator and a second rectifier/inverter. Both rectifier/inverters are interconnected by a dc link and include switching devices. A filter is connected between the second rectifier/inverter and the network. A first controller for the first rectifier/inverter uses a dc link voltage demand signal indicative of a desired dc link voltage to control the switching devices of the first rectifier/inverter. A second controller for the second rectifier/inverter uses a power demand signal indicative of the level of power to be transferred to the dc link from the network through the second rectifier/inverter, and a voltage demand signal indicative of the voltage to be achieved at network terminals of the filter to control the switching devices of the second rectifier/inverter.

摘要： A motor driving apparatus wherein provisions are made to ensure that the regenerative operation of a rectifier continues as long as the supply of power from an inverter continues, and that the regenerative operation of the rectifier stops when the supply of power from the inverter ends. The apparatus includes: a detection unit which detects an input voltage and current; an instantaneous effective power calculation unit which, based on the detected input voltage and current, calculates instantaneous effective power supplied from the rectifier to the inverter; a DC component calculation unit which, based on the value of the calculated power, calculates the DC component of the effective power; and a regenerative operation stopping decision unit which compares the value of the calculated DC component with a predetermined threshold value and decides that a power regeneration operation for feeding regenerative power from the inverter back into the power supply be stopped.

摘要： Embodiments of the present invention provide novel techniques for using a switched converter to provide for three-phase alternating current (AC) rectification, regenerative braking, and direct current (DC) voltage boosting. In particular, one of the three legs of the switched converter is controlled with a set of pulse width modulation (PWM) control signals so that the input AC phase having the highest voltage is rectified and one of the switches in the two other legs is turned on to allow for added voltage. This switching activity allows for voltage from multiple AC line mains to be combined, resulting in an overall boost of the DC voltage of the rectifier. The DC voltage boost can then be applied to the common DC bus in order to ameliorate voltage sags, help with motor starts, and increase the ride-through capability of the motor.

摘要： Method for operating a delta wound three-phase permanent magnet brushless motor. A transition speed is determined in a quadrant of a speed versus torque curve above which speed continues to increase while current/torque decreases wherein actual phase current can be controlled in a current control modification manner which reduces requested phase current. The modification manner is determined for a quadrant, wherein a controller can use the modification manner to reduce the requested phase current to control the actual phase current when the speed is above the transition speed. The motor is controlled in a quadrant wherein, when the motor has a speed above the transition speed, the controller reduces the requested phase current in the modification manner and the controller supplies the actual phase current to the motor using the reduced requested phase current and using measured phase current of the motor derived from using a single current sense resistor.

摘要： When multiple motors (40) share a common DC power supply (10) via a bus (20), a system and method is provided for managing the effect of regenerative energy caused by a motor. The regenerative energy may be sensed, e.g., by a power electronics controller (50, 50′). In response, one or more of the other motors currently in operation may be controlled to operate according to a reduced power factor. Thus, the excess energy is consumed without adding any new components or increasing the amount of work performed in the system.

摘要： A servo motor controlling method includes: directly or indirectly detecting a position of a moving body which performs a circular-arc interpolation feeding motion by a servo motor; performing a feedback control for enabling the position of the moving body to comply with a position command; and at a quadrant changing time when a moving direction of the moving body is changed, performing torque correction on a torque command value according to a distance from a position where the moving direction is changed. By this method, a quadrant protrusion and a torque change with respect to a friction caused from a free zone at a time of reversion of a ball screw can be appropriately corrected. Especially, by performing a first torque correction for a static friction at the position where the moving direction is changed, and by performing a second torque correction for a moving friction after movement by the distance corresponding to the free zone, more appropriate correction can be obtained.

摘要： A large amount of heat generation is incidental to conventional power conversion devices due to large ion voltage of a diode element rectifying AC power to DC power. Moreover, in the heat generation, power generation operation has to be stopped to prevent burnout of the diode element, resulting in restriction on power conversion functions. In the power generation mode that diode elements 4 rectifies an AC power generated by a generator-motor 6, a diode element being in conduction state is detected out of the diode elements 4 in accordance with an output signal from a current sensor mounted on an AC power line of the generator-motor 6, and a switching element 3 that is connected in parallel with the diode element 4 is turned ON. Most of current of the diode element 4 flow through the switching element 3, resulting in reduction of heat generation of the diode element 4.
