In this brief, a nonlinear averaged model is derived to describe the nonlinear time-periodic coupling (NTPC) effect of the SIDO PFC converter, and importantly time-frequency characteristic representation method is proposed to obtain the analytical expression of periodic equilibrium solutions. Furthermore, two types of slow-scale oscillations are identified with the help of the loci movement of Floquet multipliers. It is shown that period-doubling bifurcation and Hopf bifurcation are responsible for type I alternating peak oscillation and type II discontinuous trajectory oscillation, respectively. Especially, Hopf bifurcation results in one incommensurable frequency component with respect to the line frequency, which explains the reason why the system enters one quasi-periodic orbit. Finally, these experimental results are given to verify the theoretical analysis. These above results are beneficial to guide circuit optimal design.","PeriodicalId":13101,"journal":{"name":"IEEE Transactions on Circuits and Systems II: Express Briefs","volume":"72 9","pages":"1308-1312"},"PeriodicalIF":4.9,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144914188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Attaining a decent trade-off between accuracy and speed is critically important for the effective physical deployment of networks on resource-constrained edge devices. Towards this challenging task, we propose an efficient basic block that is designed to leverage local, short-range, and long-range contextual information at different abstraction levels. We introduce a simple technique inside the basic block, called Iterative Context Embedding (ICE), to reinforce the short and long-range contextual details in an iterative fashion. Based on the resulting short and long-range ICE or SLICE module, we propose an ultra-lightweight network, called SLICENet. Our model is the fastest among the existing ultra-lightweight models while achieving a decent accuracy. Specifically, with only 0.3 million parameters, it achieves 69.1% mean IoUs on the cityscapes test set, making it the smallest model to achieve this accuracy. In addition, it achieves an inference speed of 224.8 frames per second (FPS) on the RTX 3090 with <inline-formula> <tex-math>$512times 1024$ </tex-math></inline-formula> resolution. To achieve a power-efficient solution meant for battery-operated devices, we also deploy our model on Xilinx’s ZCU102 development board (Zync UltraScale+ MPSoC). Despite achieving an impressive performance, its power consumption is only 950 mW; significantly lower than GPU-based inferences.

First, by employing subsystem transformation, the optimal controller design problem for MJSs is reformulated into solving a set of parallel and decoupled algebraic Riccati equations (DAREs). Traditional learning schemes for solving these equations either require initially admissible control policies or suffer from slow convergence. To overcome these limitations, a novel scaling-based reinforcement learning algorithm is proposed. Several notable advantages are exhibited by the proposed algorithm: it eliminates the need for system dynamics during the learning process, achieves faster convergence, and relaxes the requirement for an initially admissible control policy. The effectiveness of the proposed scheme is rigorously proven through a mathematical induction method. Finally, the feasibility of the proposed scheme is verified using an operational amplifier circuit example, and its superiority is demonstrated through a series of comparative simulations.","PeriodicalId":13101,"journal":{"name":"IEEE Transactions on Circuits and Systems II: Express Briefs","volume":"72 9","pages":"1238-1242"},"PeriodicalIF":4.9,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144914142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among them, mitigating complex cross-coupling in magnetic couplers remains critical to achieving high efficiency and stable power delivery. Thus, this brief proposes a compact dual-channel WPT system with decoupled coils to enhance the overall power capacity. The transmitter and receiver have the same structure, with each charging pad constructed by solenoid coils wound around Q-coils and ferrite cores. Solenoid coils and Q-coils are naturally decoupled from each other, thereby eliminating additional coupling interference and only their main mutual inductance <inline-formula> <tex-math>$M_{1}$ </tex-math></inline-formula>, <inline-formula> <tex-math>$M_{2}$ </tex-math></inline-formula> are retained. Furthermore, the principle of power enhancement and constant current (CC) output is thoroughly analyzed, and a more generalized output model is derived. Finally, a 305 W experimental prototype was constructed, with results in agreement with theoretical analyses.
