摘要： A control device includes: a prediction unit configured to predict the harmonic current at each of prediction points comprised in a predetermined prediction target period after current time, based on control information of the motor in at least a next carrier cycle of the inverter, and a command value determination unit configured to output, to the active filter unit, a current command value for generating a compensation current having a polarity opposite to a polarity of a harmonic current at a prediction point, at a timing corresponding to the prediction point comprised in the next carrier cycle in the prediction target period, based on a prediction result of the prediction unit. Each of the prediction points is provided at a predetermined time interval since start time of the prediction target period. The time interval is longer as the next carrier cycle is longer.

摘要： An active electromagnetic interference (EMI) filter includes a first amplifier and a second amplifier. The first amplifier is configured to sense noise signals on a power conductor. The second amplifier is coupled to the first amplifier and is configured to drive a cancellation signal onto the power conductor. The cancellation signal is to reduce the amplitude of the noise signals sensed by the first amplifier. An output impedance of the second amplifier is lower than an output impedance of the first amplifier.

摘要： A method for operating a multilevel converter in flycap topology, in which the multilevel converter has at least two semiconductor switches controlled by control pulses of variable pulse durations within a control period that recurs at a control frequency to selectively interconnect a voltage source connected to an input of the multilevel converter, an output of the multilevel converter, and at least one auxiliary capacitor arranged between the input and the output, for generating an output voltage. The method includes using at least one oscillation parameter that describes the oscillation behavior of at least one harmonic of an electrical measured variable, at least one correction pulse duration is determined for a future control pulse to reduce the amplitude of the at least one harmonic and at least one semiconductor switch is controlled with a control pulse of the determined correction pulse duration.

摘要： An ultracapacitor module may include an ultracapacitor cell stack, a boost/buck DC/DC converter, a temperature sensor configured to measure a temperature T, a voltage sensor configured to determine an operating voltage Vo of the voltage supply bus; and an electronic controller connected with the DC/DC converter, the temperature sensor, and the voltage sensor. The ultracapacitor cell stack and the DC/DC converter are connected with the voltage supply bus, The electronic controller is configured to determine an initial voltage value Vi corresponding to the measured temperature T, determine an adjustment voltage value Va when the rate of change dV/dt of the operating voltage Vo is less than a predetermined threshold, calculate a target bus voltage value Vt using a first formula Vt=Vi+Va, and control the DC/DC converter to be in a boost mode or a buck mode to maintain the voltage Vo near the voltage value Vt.
