One example is a ultra-high BW 4.8 MHz parallel-interleaved multi-level GaN inverter AC power source with a target output BW of 100 kHz. This work investigates the combination of state-of-the-art Hall-effect current sensors with a suitable high-frequency (HF) sensor to extend the BW of the commercially available current sensor by a factor of 20 – 50, i.e., up to 10 − 20 MHz. The main focus lies on a small form factor and a low realization effort. HF current sensors based on a Rogowski coil, an inductor integrated voltage sensing and a current transformer (CT) are analyzed and compared. Additionally, their respective performance limitations are highlighted. Furthermore, a precise combiner network to combine the low-frequency (LF) and HF signal is analyzed. The combiner circuit is designed in a way that component tolerances have no influence on the behavior in the transition frequency range from LF to HF. Thereby, also the immunity to Common-Mode (CM) disturbances, i.e., the high dv/dt occurring for the switching transitions of WBG semiconductors is considered. Finally, a hardware demonstrator featuring the two most promising current sensor approaches, i.e., the inductor voltage sensing and the CT, is presented and verified with comprehensive measurements in frequency and time domain. A BW from DC up to 35 MHz is measured. The realized sensors are further tested with a hardware prototype of the aforementioned AC power source switching 600 V at an effective switching frequency of 1.6 MHz. The measurements clearly reveal that both proposed sensor concepts are well suited for accurate measurements in fast switching converter systems with negligible additional volume.","PeriodicalId":7050,"journal":{"name":"2021 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88000843","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}

Model Predictive Control (MPC) is the only reported advanced technique that engages the dynamical model of capacitors in control equations to regulate the dc-links voltages. MPC however causes variable switching frequency that escalates dv/dt as well as power losses. Variable switching frequency also distributes the harmonic content of the converter current that is a serious challenge to design passive filters. This paper proposes a simple low frequency control technique based on backstepping theory to apply direct voltages control to dc-link capacitors in a promising grid-connected BCMC namely nine-level Packed E-Cell (PEC9) converter. Simulation and experimental results validate the success of the proposed backstepping-based nonlinear technique in fulfilling the desired control objectives including accurate reference current tracking, low THD, standard dc voltage ripple and minimum steady state error and transient effects under stable and unstable conditions.","PeriodicalId":7050,"journal":{"name":"2021 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91549692","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}

To help the designers better select the suitable voltage clamping components or circuits for SSCBs or HCBs, this paper surveys and compares various voltage clamping components (e.g. metal oxide varistors, transient voltage suppression diodes, capacitor based snubber circuits, etc.) in terms of operating voltage ranges, surge current capability, energy absorbing capability, cost, etc. A voltage clamping component with lower peak clamping voltage is preferred for SSCBs, as the SSCB can operate at a higher DC bus voltage for a certain voltage rating (e.g. 1200V) solid state switch. The voltage clamping performances are also experimentally evaluated by measuring the ratio of peak clamping voltage and the maximum operating voltage (Vpk/Vop). Finally, the advantages and limitations of different voltage clamping components are discussed and summarized to facilitate the SSCB design.","PeriodicalId":7050,"journal":{"name":"2021 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87628611","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 the proposed method, first Finite Control Set Model Predictive Control (FCS-MPC) is used to generate the reference voltage by inspecting all the possible converter output voltages taking into account the control delay. Then, the generated reference is applied to a modulator operating with Phase Shifted Pulse Width Modulation (PSPWM) scheme. The application to the modulator ensures a constant output switching frequency and proper voltage balancing of the flying capacitors (FCs’). The proposed method is easy to implement and provides a fast dynamic response, robustness to the load change, constant switching frequency, and decreases the computational burden of traditional FCS-MPC. Finally, the performance of the FCS-M2PC is verified by implementing different scenarios on a experimental setup and the results are presented.","PeriodicalId":7050,"journal":{"name":"2021 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88954260","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}
