“…And for the traditional Pareto optimization, Pareto front of the two optimization indexes can be drawn as a curve, which can be visually displayed on a two-dimensional plane. However, the Pareto front of three or more optimization indexes is a hypersurface, which cannot be visually displayed by two-dimensional graphics, thus increasing the difficulty in determining the final optimization results [32]. Therefore, it is very meaningful to improve the traditional Pareto optimization process so as to intuitively select the final optimization results and reduce the difficulty of optimization results selection.…”

This paper focuses on the design, analysis, and multi-objective optimization of a novel 5-degrees of freedom (DOF) double-driven parallel mechanism. A novel 5-DOF parallel mechanism with two double-driven branch chains is proposed, which can serve as a machine tool. By installing two actuators on one branch chain, the proposed parallel mechanism can achieve 5-DOF of the moving platform with only three branch chains. Afterwards, analytical solution for inverse kinematics is derived. The 5 $\times$ 5 homogeneous Jacobian matrix is obtained by transforming actuator velocities into linear velocities at three points on the moving platform. Meanwhile, the workspace, dexterity, and volume are analyzed based on the kinematic model. Ultimately, a stage-by-stage Pareto optimization method is proposed to solve the multi-objective optimization problem of this parallel mechanism. The optimization results show that the workspace, compactness, and dexterity of this mechanism can be improved efficiently.

“…In literature [12], a voltage multiplier unit and a switching capacitor unit are combined to achieve low voltage and low current stress efficiency between components. In literature [13][14][15][16][17], a three-phase asymmetric inductor was used to replace a three-phase discrete inductor and an integrated magnetic structure technology was adopted. is reduces the total volume of the core, thus increasing the efficiency of the system.…”

High-voltage gain converter has a high-frequency use in some industrial fields, for instance, the fuel cell system, the photovoltaic system, electric vehicles, and the high-intensity discharge lamp. In order to solve the problem of the low-voltage gain of traditional boost converter, the double-boost converter with coupled inductance and doubled voltage is proposed, which connects the traditional boost converter in parallel. The voltage gain of the converter is further improved by introducing the voltage-doubled unit of the coupled inductance. Moreover, the clamp capacitor can absorb the leakage inductance in the circuit and reduce the voltage stress of the switch. In addition, two coupled inductors are magnetically collected; then, the loss of the core is analyzed under the same gain. The detailed analysis of the proposed converter and a comparison considering other topologies previously published in the literature are also presented in this article. In order to verify the proposed converter performance, a prototype has been built for a power of 200 W, input and output voltages of 12 and 84 V, respectively, and a switching frequency of 50 kHz. Experimental results validate the effectiveness of the theoretical analysis proving the satisfactory converter performance, whose peak efficiency is 95.5%.
