This technology offers significant levelized cost of energy reductions via capital expenditure and operating expense savings - a crucial objective for the offshore industry. The direct-drive (DD) PMG technology uses ferrite magnets to create the magnetic field, which is a significant source of cost reduction. The use of ferrite could also eliminate an industry wide reliance on neodymium iron boron, the scarce and expensive rare-earth magnet used in existing designs. Another benefit of using ferrite-based design is that it is less sensitive to the cooling problems that currently face existing DD-PMGs. Further technical advantages come in the form of magnetically balanced axial design, optimized magnet and aluminium/copper ratio, insensitivity to air gap and cogging elimination. This paper details aspects of design, construction, thermal performance and testing of a nominal 250 kW power rating prototype.","PeriodicalId":188371,"journal":{"name":"The 10th International Conference on Power Electronics, Machines and Drives (PEMD 2020)","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124679068","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}

The high-cell count in these applications means that for a given voltage conversion ratio there are theoretically a large number of alternative topologies that can be synthesised. However, each of these topologies may exhibit different competing characteristics, for example total VA rating of capacitors, total VA rating of switches, number of switches and individual switch voltage rating. Obtaining an optimum topology in terms of given design constraints is therefore important requirement. This paper builds on previous work by the authors by presenting a method for the automatic calculation of the voltage ratings of the components in a SC converter. This result along with earlier work, allows for the calculation of VA ratings, which are an important metric when comparing competing circuits. In addition, a new Canonical Cell topology is presented that extends the range of SC circuits that can be analysed using this method, to cover so-called Ladder circuits. The method is validated against detailed Spice simulations and measurements from a hardware prototype.","PeriodicalId":188371,"journal":{"name":"The 10th International Conference on Power Electronics, Machines and Drives (PEMD 2020)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127656983","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}

The power electronic devices driving the electrical motor in this system are often integrated within one power module, complicating temperature measurements and monitoring of the semiconductor devices. Therefore, accurate thermal models of these modules are necessary. The main challenge remains to model these thermal properties sufficiently accurate to estimate the device temperatures, while maintaining an evaluation speed fast enough to ensure safe operating temperatures in real-time. Furthermore, in the search for enhanced cooling methods, it may be interesting to compare cooling designs using simulations before or instead of experiments. To this end, this paper develops and compares the accuracy of a 3D grey-box Lumped Parameter Model of an IGBT module coupled with an interchangeable cooling model with two 1D Lumped Parameter Models. The 3D model is based on a Finite Element representation, while the 1D models are based solely on datasheet information. The different model types are discussed and compared regarding their accuracy using simulation and experimental results.","PeriodicalId":188371,"journal":{"name":"The 10th International Conference on Power Electronics, Machines and Drives (PEMD 2020)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114279795","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}

It is well known that the gate oxide in SiC MOSFETs is not as reliable as that in silicon MOSFETs due to increased fixed oxide and interface traps. Numerous studies have shown reduced performance on time-dependent dielectric breakdown (TDDB) and oxide robustness in SiC MOSFETs compared to silicon devices. On the one hand, a high ON-state gate-source voltage VGS is required for proper channel inversion, low ON-state loss and fast switching while on the other hand, a lower ONstate VGS reduces the electrical stress on the gate oxide and improves long term reliability. Understanding the implications of the selected gate voltage on the operation of the power device will be fundamental for achieving an optimal balance between electrical performance and gate oxide reliability. This paper shows that reducing the maximum gate driver supply voltage VGG only affects turn-ON losses while turn-OFF losses are independent of VGG. The experimental characterisation is complemented with electrothermal simulations to evaluate the impact of the gate voltage on the operation of a converter. The paper shows that reducing VGG by 10% causes an increase of 7.6% in the device losses and 1.4 °C in junction temperature in simulated converter operation. Furthermore, if the switching speed is increased by means of reducing the gate resistance, the impact of the conduction losses can be compensated. These results are fundamental for balancing system efficiency and reliability in SiC MOSFETs.","PeriodicalId":188371,"journal":{"name":"The 10th International Conference on Power Electronics, Machines and Drives (PEMD 2020)","volume":"24 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114085894","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}
