摘要： A method for attenuating switching noise from back electromotive force (EMF) observations in a motor is described. The motor is controlled by pulse width modulation (PWM) signals provided at a PWM frequency. The method comprises sampling back EMF observed in the motor at a sampling frequency at least two times greater than the PWM frequency to obtain over-sampled back EMF readings. The oversampled readings may be used in a raw or filtered form to commutate the motor. A system implementing the method is also described.

摘要： A variable speed drive with a boost converter is provided for a chiller system driven by an induction motor. The boost converter can be a diode or thyristor rectifier followed by a boost DC/DC converter or a three-phase pulse width modulated boost converter. The boost converter provides a boosted voltage to the DC link, which results in a boosted voltage being applied to the induction motor by the inverter of the variable speed drive.

摘要： A motor driving apparatus including a regeneration control function and a power storage device for accumulating a regenerative current and for supplying an inverter section with electric power during acceleration. The inverter section is connected to a converter section by a DC link to which regeneration start detecting means and the power storage device are connected. When the regeneration start detecting means detects that a voltage at the DC link reaches a regeneration control start voltage, a controller controls switching elements and starts regeneration control. The regenerative current is accumulated in the capacitor through a diode. When a motor is in a power running state, the switching elements are turned on to apply the voltage at the power storage device to the DC link, and the charged power is utilized for motor acceleration. At that time, the regeneration control start voltage for the regeneration start detecting means is made higher, thereby preventing regeneration control from being activated due to application of the capacitor's voltage. Not only the regenerative current is effectively utilized by the power storage device, but also the regeneration control function can be utilized.

摘要： A method of compensation for current-sensor gain errors in an electric machine drive 14 includes a high frequency carrier signal electrically injected into the electric machine 14. A current-sensor signal of the electric machine 14 is determined. The current-sensor signal is separated into current-sensor carrier signal negative and current-sensor carrier signal positive sequence reference frames. A proportional compensator signal for one of the current-sensor carrier signal reference frames is generated in a feedback loop 24. A magnitude signal of another one of the current-sensor carrier signal reference frames is generated in a different feedback loop 26.
