Abstract This paper proposes a fault diagnosis method for wireless charging system (WCS) of new energy vehicles based on Particle Swarm Optimization (PSO)-IBP. Firstly, the momentum factor and learning rate back propagation (BP) neural network are optimized. Secondly, improved BP PSO algorithm fused to improve accuracy. Finally, taking equipment as an example, it is verified that proposed can achieve fast accurate in WCS vehicles.

A Novel Optimization Method of the DS-LCC Compensation Topology to Reduce the Sensitivity of the Load-Independent Constant Current Output Characteristics to the Component Parametric Deviation

Electronics, Journal Year: 2025, Volume and Issue: 14(8), P. 1536 - 1536

For the double-sided inductor–capacitor–capacitor (DS-LCC) compensation topology, parametric deviation of elements results in mismatch between resonant frequency and operating frequency. Furthermore, this leads to loss load-independent constant output characteristics. Therefore, an innovative design approach based on reduction capacitance ratio is proposed attain current under deviation. With presented method, simply by reducing capacitor ratio, characteristics can be preserved, fluctuations transmission gain caused are minimized. This implies that when achieved modulation (FM) control, required FM range reduced. Finally, from experimental results, load 3 Ω 33 Ω, compared high maintained at low ratio. In addition, without deviation, efficiencies different ratios basically same 93.5% 94.2%, respectively. However, deviations 87.4% 84.9%, but only 73.9% 68.2%
