   A Simple State-Based Prognostic Model for Predicting Remaining Useful Life of IGBT Power Module
By Alireza ALGHASSI [View]
[Download]

Abstract: Health management and reliability are fundamental aspects of the design and development cycle ofpower electronic products. This paper presents the prognostic evaluation of a power electronic IGBTmodule. To achieve this aim, a simple state-based prognostic (SSBP) method has been introduced andapplied on the data which was extracted from an aged power electronic IGBT and its remaining usefullife was determined.

   Arcing Characteristics on Low-Voltage DC Circuit Breakers
By Hyosung KIM, Lee SUNGMIN [View]
[Download]

Abstract: Removing the fault current in DC circuits is comparably difficult since the DC current has non zero-crossing point like in AC current [1,2]. Thus, developing dedicated DC circuit breakers is necessary to get safety for human body and electrical facilities [3,4]. This paper proposed a novel DC circuit breaker against inductive loads. The performance of the proposed DC circuit breaker was verified by an experimental circuit breaker test system.

   Basic Design Considerations for a Mechanically Switched Capacitor with Damping Network (MSCDN) within a High-Voltage-Grid
By Henning ZIMMER, Julia DRAGON, Jutta HANSON [View]
[Download]

Abstract: Because of the ambitious plans of the German government to have 80 \% renewable electric energy production by 2050, the German transmission system operators (TSOs) are facing difficult decisions when it comes to supplying sufficient amounts of reactive power to provide voltage stability and sufficient transmission capacities without building a large numbers of new transmission lines. One possible solution is the installation of capacitive compensation units to provide reactive power. A special form of capacitive compensation is the mechanically switched capacitor with damping network (MSCDN). This paper gives a brief insight into the basic design considerations for an exemplary MSCDN including the dimensioning of the basic components and the calculation of operation voltages and currents using a simple equivalent circuit diagram. It is also discussed how capacitor and reactor losses could be included into the modeling of the MSCDN. An approach for dimensioning the damping resistor is shown. Furthermore, basic switching phenomena have been simulated using a MATLAB SimPowerSystems model.

   Design of Passive Trap-LCL Filters for Two-Level Grid Connected Converters Applications
By Antoni Mir CANTARELLAS, Elyas RAKHSHANI, Daniel REMON, Pedro RODRIGUEZ [View]
[Download]

Abstract: This paper proposes a passive filter design method and validation analysis based on a Trap-LCL filtertopology for implementation in grid connected two-level converters for high power applications. Theproposed topology appears as an alternative to the conventional LCL filter, since reduced filterparameters can be obtained while still ensuring high filtering capability for switching frequencyharmonics. Furthermore, a step-by-step filter design method will be introduced in order to provide aclear scope on the tuning procedure, as well as on the main requirements that the filter should satisfy.Finally, a comparative study between a conventional LCL and a LCL-Trap filter will be performed insimulation with the goal of finding a meaningful evaluation of the advantages and disadvantagesprovided from the LCL-Trap configuration.

   Fundamental Study of an Intelligent Power Routing Switch Based on a SiC DC–DC Converter for Next Generation DC Distribution Network
By Yusuke HAYASHI, Akira MATSUMOTO [View]
[Download]

Abstract: A power routing switch using SiC–MOSFET has been developed for the future DC distribution network. The routing switch behaves as an intelligent relay, a circuit breaker and an inrush avoiding circuit. The circuit configuration of the routing switch is based on the non–isolated hard–switching DC–DC converter, and the surge voltage across the SiC–MOSFET is minimized by managing circuit parasitic parameters to prevent malfunction of peripheral equipment. The high frequency digital control has been applied, and the fault current has been interrupted within several microseconds after the accident. A 5 kW and DC 380 V prototype has been fabricated and the performance as the circuit breaker and the inrush avoiding circuit has been evaluated experimentally. The fault current of 37 A has been interrupted within 5 μs after the detection of the fault current of 22 A, suppressing the overshoot voltage of the SiC–MOSFET lower than 500 V. The inrush current has been also avoided by the PWM soft–start operation for the capacitive load without any external protection equipment. The developed switch works as the multifunction circuit protection device and realizes the flexible intelligent power routing by taking the control strategy for the next generation DC network into account.

   Single-Phase Frequency Detector Algorithm Applied to Grid-Connected Power Conditioning Systems
By Vinicius BACON, Sergio SILVA, Leonardo CAMPANHOL [View]
[Download]

Abstract: This paper proposes a single-phase algorithm used to estimate the frequency, as well as the phase-angle of the utility grid. The algorithm uses self-tuning filters (STFs) operating in conjunction with low-pass filters (LPFs). The STFs are used to extract the fundamental components of the orthogonal voltages that represent a fictitious two-phase stationary reference frame (αβ-axes), while the LPFs are employed for frequency detection purpose. Therefore, both the STFs and the LPFs must be properly adjusted to avoid the compromising of the algorithm transient response. The operation principle of the proposed algorithm is presented, which is based on the frequency response analyses of both the STFs and the LPFs involved. Furthermore, simulation and experimental results are presented in order to validate the theoretical development, as well as verify the performance of the proposed synchronization algorithm under utility grid disturbances, such as voltage harmonics, voltage sags and swells, phase jumps and frequency variations.

   The Simulation Analysis of the interaction between Solid State Power Controller and Brushless Direct Current Motor
By Weiyang CHEN, Xiaolin WANG, Ligang RUAN, Li WANG [View]
[Download]

Abstract: As a kind of important loads on electric vehicles(EVs), brushless DC motors(BLDCMs) encounter the problems of large starting inrush current, high security hidden trouble caused by capacitive residual voltage, etc. Solid state power controllers(SSPCs) sh ow advantage in handling such trouble. In this paper, SSPC and BLDCM are modeled. The interaction between SSPC and BLDCM is analyzed during motor starting period, capacitance charging-discharging process, motor loading process and short-circuit protection process. Power quality is evaluated in 270VHDC system. Results show that SSPC can effectively inhibit BLDCM starting inrush current and eliminate the security risk of high capacitor residual voltage. SSPC can trip immediately when BLDCM is overloaded severely or short-circuit. It’s feasible to apply SSPC in HVDC system of electric vehicle.
