This has negative effect during torque transients. Before an increased torque can be produced, flux linkage has to be built up which is limited by the rotor time constant. Transient torque response can be improved by boosting the flux linkage with a high current for a short time. However, a maximum inverter current limit exists which is a mutual constraint for the flux-producing and torque-producing current components. Known current sharing methods usually apply a constant flux-boosting current or only consider the next controller sampling time instant for optimization which leads to a non-optimal current trajectory. Aim of this paper is a full optimization of the current trajectory considering the whole transient process between two steady-state operating points. This is achieved by a model predictive approach with a prediction horizon in the range of the rotor time constant. The optimal trajectories are calculated offline and are analyzed to formulate a general optimization function which can be implemented on a microcontroller for real-time operation.","PeriodicalId":411916,"journal":{"name":"2017 IEEE 12th International Conference on Power Electronics and Drive Systems (PEDS)","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114413771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, MOSFET with low voltage stress and low conduction resistance can be utilized. Asymmetric PWM scheme is used to achieve low switching losses and high circuit efficiency. Input flying capacitors are used in the primary side to balance input split voltages. The voltage stress of each power switch is clamped at one third of input voltage.

Different strategies have been developed among which the permanent magnet temperature observer (PMTO) stands out given its independence from signal injection and thermal models. In spite of its uncomplicated implementation, PMTO accuracy and sensitivity had been not deeply studied. This contribution presents a sensitivity analysis of the PMTO considering manufacture tolerances in the sensors that influence its performance: position, current, and DC-link voltage sensors. Results from Monte Carlo simulations showed a complex interaction between the sensor tolerances and achievable observer accuracy. While current sensor deviations play a minimum role in PMTO accuracy, voltage and position sensor deviations are critical. A statistical analysis reveled that a production quality control based on a sample of the population is not enough to guarantee an appropriate PMTO accuracy. Thus, specific sensor deviation ranges are required and were determined in this contribution.","PeriodicalId":411916,"journal":{"name":"2017 IEEE 12th International Conference on Power Electronics and Drive Systems (PEDS)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116275307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A significant turn-on loss reduction of up to 55 % has been observed for SiC-MOSFETs. The gate driver approach uses a transformer which couples energy from the power path back into the gate path during switching events, providing increased gate driver current and thereby faster switching speed. The gate driver approach was tested on a boost converter running at a switching frequency up to 300 kHz. With an input voltage of 300 V and an output voltage of 600 V, it was possible to reduce the converter losses by 8 % at full load. Moreover, the output power range could be extended by 23 % (from 2.75 kW to 3.4 kW) due to the reduction of the turn-on losses.","PeriodicalId":411916,"journal":{"name":"2017 IEEE 12th International Conference on Power Electronics and Drive Systems (PEDS)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125355557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition to weight and possibly size reduction, solid-state transformers can provide enhanced controllability. Emerging silicon carbide (SiC) power devices that can block higher voltages, conduct current more efficiently, and switch faster than silicon power devices are providing a new impetus to the development of SSTs. This paper discusses several versions of MVA-scale SSTs designed for medium voltage AC or DC applications using modular power electronic building blocks.

For synchronous machines the stator and pole configuration is commonly chosen according to the highest winding factor and lowest air-gap leakage factor. However, this does not always lead to the best machine. Due to the discrete field distribution of concentrated tooth windings, the air-gap harmonic content increases. This results in a high leakage inductance and a high leakage factor and consequently in a low saliency ratio of the machine. In addition to the theory of winding- and air-gap leakage factors for synchronous machines this paper introduces an analytic torque factor which is valid for all stator and rotor configurations. The torque factor describes the rotor pole utilization depending on the winding configuration. The presented discussion is based on analytic equations and finite element simulations of two segmented synchronous reluctance machines.","PeriodicalId":411916,"journal":{"name":"2017 IEEE 12th International Conference on Power Electronics and Drive Systems (PEDS)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124125543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
