Moreover, for the power electronics protection system, it is also important to enable the system with a fault current limitation capability. Accordingly, this paper aims to design an intelligent gate drive for DC-SSCB, which can operate in cryogenic conditions to increase interrupting capability of the SSCB. Meanwhile, the proposed intelligent gate drive also enables the SSCB to operate in the current limitation mode to limit the overcurrent in the aviation system. The current limitation mode can help the aviation system limit the inrush current during startup and realize fault ride-through for the healthy part when the fault occurs. Finally, test results based on a 200V/150A SSCB with the current limitation mode prototype verify the proposed intelligent gate drive design for SSCB with cryogenic cooling.","PeriodicalId":151216,"journal":{"name":"2023 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128799362","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 500W prototype has been built and tested to verify the operation of the converter. The experimental results verify that the converter can achieve MPPT for each PV panel.

The starting-up process of the DAB may induce a large inductor current and endanger the safe operation of the system. In addition, the parameters of the controller during the starting-up process should also be considered. This paper provides a novel starting-up method for DAB if the input voltage rises gradually. Using the given method, the starting-up process can be divided into three stages, including the input capacitor charging stage, open-loop control stage, and closed-loop control stage. The computer assistant simulation is used to determine the parameters of the controller. An experimental prototype is built to verify the effectiveness of the proposed method. The theoretical analysis, simulation result, and experiment result match well. The inductor's inrush current can be reduced effectively using the given method.

The readout interface is implemented in the XFAB 180 nm SOI process. It amplifies the outputs from a low and a high frequency sensor and aggregates their response in an appropriate proportion in the frequency domain to achieve a flat wideband response. The system bandwidth of DC - 42.8 MHz is achieved. The amplifiers are compensated using the feedforward technique, which does not compromise bandwidth for stability. The output step response of 2.51 V amplitude is achieved with 19.84 ns of rise time in response to sensed step current of 10 A amplitude and 5 ns rise time. Hence, the measured sensitivity of the hybrid sensor with an on-chip readout interface is 251 mV/A.

The three-phase input voltages are modulated by two AC to AC converters to generate a high-frequency link at 20 kHz. The high-frequency link is then interfaced to two three phase rectifiers configured in 12-pulse by means of a high-frequency open-delta transformer arrangement. With the transformer core operating at high frequency operation, it is shown that the proposed configuration operates as a conventional line-frequency 12-pulse, resulting in high quality input currents with low THD. Furthermore, a phase shifted modulation is introduced to achieve zero voltage switching and to regulate the output DC voltage. An added benefit of the approach is the ability to regulate the output DC voltage/current by means of a simple duty cycle control of the high frequency (20kHz) modulating signal. The overall three-phase input currents are of high quality and near unity power factor due to the cancellation of 5th and 7th harmonics. The proposed approach substitutes the bulky line-frequency transformer with a high-frequency transformer, thereby achieving higher power density. Derivation of a small signal model of the converter is discussed for the design of DC closed loop. A 208 V 3-phase laboratory prototype demonstrates the validity of the concept.","PeriodicalId":151216,"journal":{"name":"2023 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129024577","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}

Due to their high frequency variation in synchronous reference frame and non-linear inductance variation, the suppression of the circulating currents is a challenging task. Following the principles of digital sliding-mode control, the proposed controller is capable of effectively suppressing the circulating currents. The performance evaluation of the proposed controller is performed in two modes, viz, equivalent control law based and equivalent control law with disturbance compensation. The former ignores the effect of inherent disturbances while the latter uses a simple unit time-steps delayed disturbance approximation. In this paper,the performance of both methods is compared to a conventional PI regulator in MATLAB/Simulink, and simulation results are verified experimentally. It is proved that the two proposed methods have better performances compared with PI controller.","PeriodicalId":151216,"journal":{"name":"2023 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129453335","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}
