“…The sampling frequency of 5 kHz was equal to the switching frequency. The LC filter was designed to have a cutoff frequency of 566 Hz in order to meet a rule of thu mb that the cutoff frequency should be about one decade below the switching frequency and one decade above the nominal fundament al frequency [7]. The fundamental-frequency voltage drop in the filter inductance was chosen to be less than 5 % of the no minal voltage in the nominal operating point [8].…”

“…1, which is due to input/output filter oscillation currents. This technique has previously been applied to control differentialmode disturbances due to interactions of the input or output harmonic filter in voltage-mode modulated converters with high bandwidth capability [17], [18]. The differential-mode THD will be compromised for the converter that incorporates the CMCR because the CMCR will force the selection of nonadjacent switch states, whereas the D-and Q-axis current regulators tend to force the selection of adjacent states if one of the resultant three phase voltage references to the modulator is allowed to be dependent on the other two phase references.…”

A mathematical model that is developed for a generalized drive system, including common-mode passive and active elements, is used to explore the issues of paralleling soft-switched resonant dc-link drive systems. Differences between the modulation pattern for each drive system cause common voltage disturbances, which lead to significant circulating currents between the drive systems. Control methods for actively compensating for common-mode circulating currents or reducing the commonmode voltage disturbances are investigated. Practical modifications to the drive system controls are implemented to reduce the circulating currents between paralleled systems.Index Terms-Component, drive system modeling, electromagnetic interference (EMI), paralleling power converters, softswitched power converters.

Distributed generation (DG) systems should goes into intentional islanding operation to back up private emergency loads when the main grid is out of electric power. Conventional utility interactive inverters which are normally operated in current mode must change their operation into voltage mode to ensure stable supply voltage for emergency loads when intentional islanding operation occurs in DG systems. During the transfer between current mode and voltage mode, serious transient problem may occur on the output terminal voltage of the utility interactive inverter. This paper proposes reasonal inverter topology and its control algorithm for seamless transfer during intentional islanding operation in DG systems. Filter design guide line and data for LCL filter that is appropriate for the proposed control algorithm are also presented.
