Analysis and validation of novel inverter and LCC-S topology-based WPT system
Journal of Power Electronics - Tập 22 - Trang 503-512 - 2022
Hong Zhou, Haitang Liu, Qijun Deng, Li Fang
Wireless power transfer (WPT) technology has been widely researched and employed due to its advantages when compared with conventional cable-connected power transmission in terms of convenience, flexibility, security, and so on. In common wireless power transfer systems, DC sources, such as batteries and AC–DC modules, are frequently utilized in the front end of the inverters to generate a relativ...... hiện toàn bộ
Boost converter design for ferrite core compatible with strong magnetic fields
Journal of Power Electronics - Tập 22 - Trang 331-337 - 2021
Bing Bai, Xuesong Zhou
Boost converters with a ferrite core are widely used in neurostimulators. However, there may be some problems if it is used in a strong magnetic field because the saturation of the ferrite core leads to a serious decline in the inductance value. To evaluate whether a converter can work normally in a strong magnetic field, it is critical to obtain the lower limit value of the inductance of the conv...... hiện toàn bộ

Dual receiver topology for bipolar dynamic wireless power transfer systems
Journal of Power Electronics - - Trang 1-11 - 2024
Hao Qiang, Jianbo Wang, Tian Xu
Segmented dynamic wireless power transfer (DWPT) systems can solve the problems of large battery size, long charging time, and the limited driving range of electric vehicles (EVs). Aiming at the load voltage fluctuation caused by the mutual inductance drop when moving over two adjacent transmitting coils, this paper proposes a novel segmented DWPT system with dual receiver topology circuits. The c...... hiện toàn bộ
Compound control strategy for maximum power point tracking with flexible step-up converters for thin film photovoltaic module applications
Journal of Power Electronics - Tập 21 - Trang 1259-1269 - 2021
Yuhang Liu, Xiangxin Liu, Jianwei Zhang, Yufeng Zhang, Guangchen Liu
This paper proposes a novel maximum power point tracking (MPPT) algorithm for a thin-film photovoltaic (PV) module with a flexible step-up DC–DC converter. To improve the voltage rating for the thin film module, a switch-inductor zero voltage transition (SIZVT) boost converter is proposed. In addition, the proposed methodology uses a multistage variable step size (MVSS) with a power close-loop con...... hiện toàn bộ
Power quality improvements of arc welding power supplies by modified bridgeless SEPIC PFC converter
Journal of Power Electronics - - 2020
Bouafassa, Amar, Fernández-Ramírez, Luis M., Babes, Badreddine
This paper proposes an efficient bridgeless power factor corrected (PFC) modified single ended primary inductor converter (SEPIC) for arc welding power supplies (AWPS). The overall configuration is composed of two converters: (1) a modified bridgeless SEPIC PFC converter, which is controlled by a PI controller to achieve a high power factor and fast response; and (2) a full bridge buck converter w...... hiện toàn bộ
Step-up switched-capacitor multilevel inverter employing multiple inputs with reduced switches
Journal of Power Electronics - Tập 21 - Trang 986-997 - 2021
Yaoqiang Wang, Zhe Wang, Wenjun Liu, Yun Zhang, Kewen Wang, Jun Liang
A large device count, weak boosting capability, and DC voltage imbalance are common issues in conventional multilevel inverters. In this paper, a novel multilevel inverter is presented that can generate the desired number of output levels with reduced devices by using new switched-capacitor circuits (SCCs). The two input sources and capacitors in the SCC can be switched in parallel and series mode...... hiện toàn bộ
Electro-thermal model for lithium-ion battery simulations

With the extensive application of lithium batteries and the continuous improvements in battery management systems and other related technologies, the requirements for fast and accurate modeling of lithium batteries are gradually increasing. Temperature plays a vital role in the dynamics and transmission of electrochemical systems. The thermal effect must be considered in battery models. In this pa...... hiện toàn bộ
Vibration suppression control for AMB system based on static learning process and feedforward current compensation
Journal of Power Electronics - - Trang 1-13 - 2023
Caiyong Ye, Jintao Lu, Shanming Wan, Xiaodong Qi
Synchronous vibration caused by rotor eccentricity is an important obstacle to the development of an active magnetic bearing (AMB) system. To solve this problem, a novel autobalancing control strategy has been proposed, which includes a static learning process and dynamic feedforward current injection process. In this algorithm, a dynamic response process under unbalanced force is simulated by a s...... hiện toàn bộ
