“…Although the T-type converter topology exists in the literature more than one decade, there are not many studies addressing its application as rectifier. The other studies devoted for three-level T-type rectifiers are based on EMI filter size minimization [22], improved modulation scheme for neutral-point potential balancing and circulating current suppression [23], and carrier-based [24] and open-circuit [19] fault-tolerant control methods with neutral-point voltage oscillations suppression.…”

A sliding mode control (SMC) strategy with dc capacitor voltage balancing is proposed for three-phase three-level T-type rectifiers. The proposed SMC strategy is designed in the abc frame rather than the dq frame. In this case, the necessity of three-phase current transformations is eliminated. The proposed SMC is based on the errors of the line currents. The amplitude of line current references is generated by controlling the dc voltage using a proportional-integral (PI) controller. In order to obtain unity power factor, the generated reference amplitude is multiplied by the corresponding sinusoidal waveform obtained from the phase locked loop (PLL) operating with grid voltages. The dc capacitor voltage balancing is achieved by adding a proportional control term into the line current reference obtained for each rectifier leg. The performance of the proposed control strategy is validated by simulations and experiments during steady-state, transients caused by load change, and unbalanced grid conditions. The results show that the proposed control strategy offers excellent steady-state and dynamic performances with low THD in the line currents, zero steady-state error in the output voltage, and very fast dynamic response.

“…M ITIGATION of conducted emissions (CE) generated by voltage source converters (VSCs) remains a major challenge in grid-tied applications due to the multidimensional nature of electromagnetic interference (EMI) filter designs [1], [2]. Acceptable limits of CE injected by grid-tied power converters are determined by well-established standards such as FCC, CISPR 11,etc.…”

Common mode (CM) filters play a crucial role in determining adherence to conducted emissions (CE) standards for grid-tied voltage source converters. Design and implementation of such filters can be challenging since they depend on several factors like identification of CM noise paths, fidelity of passive components and discerning the frequency and amplitude of CM noise sources. In this article, a CM filter has been proposed, which uses passive components along with the converter's heat sink as a circulating return path for the CM currents. Based on the presented CM circuit models with the proposed filter, a detailed design process has been delineated for selecting the passive components required to realize the CM filter. Additionally, the heat-sink potential has been shown to be touch safe during both ideal and nonideal grid conditions with the proposed CM filter. CE spectral results measured using a commercially procured line impedance stabilization network and captured time domain converter operational wave forms for a 2-level, 3φ grid-tied voltage source converter validate the functionality and effectiveness of the presented design.

“…This approach can only be applied to the DM filter components and not to CM components because a parametrization of the volume curves is not possible for most of the commercially available CM chokes. Finally, a systematic approach for the volume optimization of a two-stage DM and CM EMI filter, essentially based on the ratio between the CM and DM inductance of the first filter stage, is proposed in [22].…”

Automatic EMI Filter Design for Power Electronic Converters Oriented to High Power Density

et al. 2018

Abstract:In this paper, a complete computer aided procedure based on the power density concept and aimed at the automatic design of EMI filters for power electronic converters is presented. It is rule-based, and it uses suitable databases built-up by considering information on passive components available from commercial datasheets. The power density constraint is taken into consideration by imposing the minimization of the filter volume and/or weight; nevertheless, the system in which the automatically designed filter is included satisfies the electromagnetic compatibility standards limits. Experimental validations of the proposed procedure are presented for two real case studies, for which the performance and the size of the best filter design are compared with those related to a conventionally designed one.
