A Kalman observer is designed to obtain the load resistance variation and the integrated voltage error which is used to compensate the current reference calculation.

The shallow P-region junction causes P-region/N- epi junction being apt to avalanche breakdown. So, trigger voltage is reduced. Furthermore, a new parasitic PNP transistor including the P-region as collector provides another leakage channel for ESD current and then the conductivity modulation in the SCR is weakened. As a result, holding voltage is increased. The physics mechanism of the above high performance is investigated via Technology Computer Aided Design (TCAD) simulation under ESD condition. We also present a detailed analysis of the current paths at trigger point, holding point and second breakdown point.","PeriodicalId":446770,"journal":{"name":"2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116443610","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}

Simulations show that the fast-scale instability which occurs around the peak value of the inductive current is a type of local instability. An improved discrete time model which can solve the problem existing in the traditional modeling method that the coefficient matrix of the system state equation is noninvertible is derived to analyze the fast-scale instability, the theoretical analysis shows that the fast-scale instability manifests itself as a period-doubling bifurcation occurs, which reveals the intrinsic mechanism of the current-source inverter. Furthermore, with the discrete-time model the stability boundary is obtained which is helpful to select the proper values of parameters for avoiding the fast-scale instability.

The equalization circuit has the advantages of simplicity and easy implementation. It achieved the controllability of bidirectional energy equalization and current size. First, the circuit’s structure and working principle are introduced. According to ACS, the simulation model of this balancing circuit with four batteries in series is built. The simulation results showed that equalization time is shortened by about 60% compared with the traditional control strategy.

The HWPT system is advantageous in that it is not sensitive to pressure change compared with conventional CPT system. Compared with IPT system, the HWPT is superior with higher efficiency. The advantages of both IPT and CPT are utilized and the shortcomings of them are tactfully avoided. For the applications like the wireless charging of Laptop, pad or drone where both IPT and CPT is realizable, it is desired to charge with HWPT system since it offers better charging robustness and system efficiency.
