“…The rectification unit, being a fixed structure (full-bridge rectification) after the resonant tank unit, is not influenced by the modulation strategy of the chopping unit. Consequently, its normalized gain can be considered as G r.normal = 1 [26].…”

The CLLC resonant converter is a widely used bidirectional power converter known for its high energy transfer efficiency. To extend its operating range, the converter often employs a hybrid modulation strategy, which is valued for its simplicity and efficiency. However, at the critical transition point between pulse frequency modulation and phase-shift modulation, instability in the output can be observed due to repetitive and unnecessary mode changes caused by noise. In order to address this issue, this paper introduces a dynamic transition algorithm integrated with hybrid modulation. This approach adaptively updates the controller parameters to mitigate oscillations resulting from improper initial parameter settings. Additionally, it incorporates error analysis and hysteresis comparison to prevent false triggers caused by noise, enabling intelligent mode adjustments. Finally, a 1 kW prototype is designed to conduct experiments, demonstrating an approximately 50% improvement in dynamic performance when the converter operates with the dynamic transition algorithm.

“…This paper builds on the previous work by formulating a tensor-based harmonic analysis tool and demonstrating the impact of correctly modelling the interaction between the AC system and nonlinear device, as well as the interaction of multiple nonlinear devices. Although there are many papers on the parameterisation of the response of nonlinear devices to terminal voltage distortion, they demonstrate the accuracy of the developed device model in isolation (e.g., [15]). In this study, a complete LV feeder is presented with a variety of nonlinear loads in each home, each represented by a detailed harmonically coupled model.…”

Over the past few decades, there have been rapid advances in solid-state technology as well as a reduction in cost. This, coupled with the functionality and efficiency improvements they afford, has resulted in a massive increase in the use of electronic devices. Where traditionally, there were a few well-known nonlinear loads that needed to be considered, now there are numerous low-power devices. Although individually insignificant, collectively, they are very significant. This paper presents a tensor-based harmonic analysis approach that is capable of capturing important interactions while being computationally efficient enough to model a large distribution system. Numerical experiments are used to highlight the advantages of the tensor framework. Numerous papers have investigated the tensor parametrisation or its mathematical equivalent—harmonically coupled admittance matrices (also known as frequency coupling matrices). However, this paper, for the first time, demonstrates how these models can be applied to perform harmonic modelling of a complete low voltage (LV) distribution system.
