Abstract: A current control module generates a voltage request based on a d-axis current (Idr) demand. A switching control module controls a motor based on the voltage request and generates an out-of-volts (OOV) signal based on a comparison of the voltage request and an available voltage. An Idr injection module generates the Idr demand based on a direct current (DC) bus voltage, a rotational speed, and a demanded torque and selectively applies a first adjustment to the Idr demand. The Idr injection module identifies whether an improvement resulted from the first adjustment, wherein the improvement is identified based on at least one of (i) a measured current of the motor and (ii) the OOV signal. The Idr injection module selectively applies a second adjustment to the Idr demand based on whether the improvement is identified.

Abstract: The invention provides a circuit arrangement including an induction motor (10) capable of being driven by an alternating current power source, a rectifier (40) for rectifying the alternating current to generate direct current for driving at least one electrical device or component associated with the motor, and a filter for reducing unwanted ripple; the filter including an inductive reactance attributable to the induction motor. This arrangement promotes economy of components and achieves effective reduction or removal of unwanted ripple and other waveforms resulting from the rectification process. Preferably a capacitor (30) is provided, either in series with the inductive reactance or in shunt therewith, to create a tuned filter with the inductive reactance. It is further preferred that the inductive reactance comprises the entire lumped inductive reactance exhibited by the induction motor, and that the reactance of the capacitor is variable, so as to permit trimming of the filter to allow for changes in the inductive reactance attributable to differing operational conditions. The invention also encompasses a domestic electrical appliance incorporating a circuit arrangement of any of the foregoing kinds.

Abstract: A compensating current is outputted except during an interval where a leakage current is not pronounced, so that losses resulting from the passage of the compensating current are reduced. A diode bridge (11) has a pair of input ends to which an alternating current is inputted from an AC power supply (3), and a pair of output ends (111, 112) which output a direct current. A boost chopper circuit (12) is connected to the pair of output ends (111, 112), and sets up a DC voltage inputted thereto. The boost chopper circuit (12) functions as a power factor correction circuit. A smoothing capacitor (13) is connected to an output side of the boost chopper circuit (12), and smoothes the voltage across the smoothing capacitor (13). An inverter (14) receives the voltage across the smoothing capacitor (13) to apply AC power to a load (4). A leakage current reduction device (2) outputs a compensating current (Ic) which compensates for a leakage current (Ia) leaking from the load (4). The leakage current reduction device (2) outputs the compensating current (Ic) except near the zero crossing of the alternating current inputted from the AC power supply (3).

Abstract: A compensating current is outputted except during an interval where a leakage current is not pronounced, whereby losses resulting from the passage of the compensating current are reduced. A converter (11) to which an alternating current is inputted from an AC power supply (3) rectifies the alternating current to output it to a DC link (15). An inverter (14) is connected through the DC link (15) to the converter (11) and converts a direct current into an alternating current to output it to a load (4). A leakage current detector (21) outputs a detection current (Ib) corresponding to a leakage current (Ia) leaking from the load (4). A compensating current output end (223) is connected to a location (41) where the leakage current (Ia) leaks, and outputs a compensating current (Ic) compensating for the leakage current (Ia) in response to the detection current (Ib). A switch (8) sets whether to input the detection current (Ib) to the compensating current output section (22) or not.

Abstract: A control system to realize input power changing along with both loads and rotate speed by an inverter bridge dragging many sets of motors, is composed of a stator voltage regulating unit(1), a motor unit(2), a rotor speed control unit(3), an inverter bridge unit(4), a control drive unit(5) and a signal processing unit(6). By setting a power factor sensor, the phase voltage and phase current of the motor stator are acquired as a control signal to regulate the input power so as to make it change with loads. At the same time, by setting a voltage sensor and a current sensor, motor rotor phase voltage, rectifier output current, overvoltage protection current and chopper working current are acquired separately as a control signal to regulate the input power so as to make it change with the rotate speed, thus realizing input power changing along with both loads and rotate speed.
