TL;DR: In this article, a novel high step-up DC-DC converter with network of switched-inductor and switched-capacitor can achieve high voltage gain under low duty cycle.
Abstract: As generally acknowledged, the high step-up DC–DC converter is widely used in the sustainable energy system as the front-end stage of the DC–AC converter. Therefore, a novel high step-up DC–DC converter is proposed in this study. The proposed converter with network of switched-inductor and switched-capacitor can achieve high voltage gain under low duty cycle. Meanwhile, the active switches and diodes suffer from low voltage stress. More importantly, an auxiliary resonant circuit with lower losses and cost is employed to realise zero-voltage switching (ZVS) turned-on and ZVS turned-off for the active switches, resulting in high conversion efficiency. Firstly, the operation principle and steady-state performance are discussed in detail. Then, prototype with power rating of 200 W is built to verify the performance of the proposed converter. The maximum efficiency of the prototype can be up to 96%, and the experimental results agree with the theoretical analysis and the simulation results well.

TL;DR: In this paper, a rectangular m × n resistor network with an arbitrary boundary is investigated and a general resistance formula between two nodes on an arbitrary axis is derived by the Recursion-Transform (RT) method, a problem that has never been resolved before, for the Green's function technique and the Laplacian matrix approach are inapplicable to it.
Abstract: A rectangular m × n resistor network with an arbitrary boundary is investigated, and a general resistance formula between two nodes on an arbitrary axis is derived by the Recursion-Transform (RT) method, a problem that has never been resolved before, for the Green's function technique and the Laplacian matrix approach are inapplicable to it. To have the exact solution of resistance is important but it is difficult to obtain under the condition of arbitrary boundary. Our result is directly expressed in a single summation and mainly composed of characteristic roots, which contain both finite and infinite cases. Further, the current distribution is given explicitly as a byproduct of the method. Our framework can be effectively applied to RLC networks. As an application to the LC network, we find that our formulation leads to the occurrence of resonances at h 1 = 1 − cos i − sin i cot n i . This somewhat curious result suggests the possibility of practical applications of our formulae to resonant circuits.

TL;DR: In this paper , the Atangana-Baleanu FOD has been applied to determine whether stability and instability appear in the RLC circuit, and the Lyapunov spectral analysis was used to analyze the trajectories of the phase state.
Abstract: The Fractional-order derivative (FOD) has a rich history in mathematical science. In comparison, the half derivative has not been extensively used in applied science and engineering. On the other hand, it is widely applicable in many branches of engineering modeling, especially control fractional-order proportional integral derivative(PID), semi-infinite lossy transmission, and many more. Thus, this work investigates the classical RLC circuit with the sense of the Atangana-Baleanu FOD. Concurrently, the Lyapunov spectral analysis is applied to determine whether or not stability and instability appear in the RLC circuit. In the first look, the RLC likes a straightforward dynamical system when the external driving force is zero. But, the dynamical system of the RLC evolves more complicated, and the wandering phase spaces do not illustrate the stability or instability when the time-dependent driving force is not zero. As a result, the Lyapunov exponents play a significant role to analyze the trait of the trajectories of the phase state. It is found from the bifurcation plots and Lyapunov exponent's spectral analysis that the non-autonomous dynamical systems lead to instability and the chaotic state with the manifestation of the local dynamical system, which switches to a stable spiral node with the presence Atangana-Baleanu FOD.

TL;DR: In this article, a series capacitor is added to the parallel resonant circuit of the receiver to compensate the gap between the transmitter and receiver coils, which can improve the power factor and power transfer efficiency.
Abstract: A cordless battery charger will greatly improve the user friendliness of electric vehicles (EVs), accelerating the replacement of traditional internal combustion engine (ICE) vehicles with EVs and improving energy sustainability as a result. Resonant circuits are used for both the power transmitter and receiver of a cordless charger to compensate their coils and improve power transfer efficiency. However, conventional compensation circuit topology is not suitable for application to an EV, which involves very large power, a wide gap between the transmitter and receiver coils, and large horizontal misalignment. This paper proposes a novel compensation circuit topology that has a carefully designed series capacitor added to the parallel resonant circuit of the receiver. The proposed circuit has been implemented and tested on an EV. The simulation and experimental results are presented to show that the circuit can improve the power factor and power transfer efficiency, and as a result, allow a larger gap between the transmitter and receiver coils.
