Abstract: The invention relates to a control device for an inverter which includes three half-bridges each having a first power switching element connected to a first DC voltage potential and a second power switching element connected to a second DC voltage potential. The control device is arranged for driving the power switching elements for converting a DC voltage present between the DC voltage potentials into a polyphase AC current in a normal operating mode and for transferring the inverter from the normal operating mode into a safe operating mode. The control device is further set up to alternately drive the power switching elements in the safe operating mode for switching single-phase active short circuits and for switching two-phase active short circuits.

Abstract: A system that may include, plural inverters connected to a common bus and at least one capacitor, the inverters configured to convert a direct current (DC) through the common bus to an alternating current (AC) by alternating different switches of the inverters between open and closed states in a respective switching cycle for each of the inverters, and a controller circuit configured to reduce a ripple current conducted onto the common bus to the inverters, by controlling the inverters to apply a frequency shift to the respective switching cycle of one or more of the inverters to spread a harmonic current spectrum along the common bus. The controller circuit is configured to apply the frequency shift to at least a first inverter and a second inverter of the plural inverters.

Abstract: The invention relates to the discharging of a DC link capacitor in an inverter arrangement, thereby allowing, for example, a DC link capacitor to be discharged while an electric machine that is connected to the inverters can operate in an idling mode as a safe mode. The DC link capacitor is discharged by very briefly triggering a semiconductor switch within the inverter. According to the invention, the inverter bridge arm with the smallest phase voltage is selected for the very brief triggering process.

Abstract: In a control unit for drive-controlling a switching element unit of each power conversion device, a voltage correction amount calculation unit calculates a correction amount corresponding to voltage drop due to impedance between the switching element unit and filter reactor. A voltage command correcting unit corrects a voltage command generated by the voltage command generation unit, using the correction amount. Thus, for a power conversion device 21 that has a small output impedance, correction is performed so as to increase the output impedance, and a PLL unit changes the frequency in accordance with active power calculated from output voltage and output current of the power conversion device, so as to uniform power allocations.
