Design of Battery Charger with USB Type-C Power Delivery Interface

title: Design of Battery Charger with USB Type-C Power Delivery Interface abstract: This paper proposes a new solution for USB Type-C power delivery (PD) chargers. This solution mainly adopts the integrated circuit (IC) AT6201Z designed by ATK. This IC has a multi-mode control strategy, which uses the Pseudo-Digital Loop (PDL) control method to change the operation mode of the converter according to the magnitude of the inductor current. PDL control method ensures loop stability and prevents system malfunctions. To prove the feasibility of the proposed solution, a prototype charger with a maximum switching frequency of 130kHz, output power of 100W, and input voltage range of 90-264Vac/50-60Hz, is designed and implemented. Based on the experimental results, the prototype has a maximum efficiency of 92%.

Simplified Model Predicts Binder Behavior in Sand Mold Printing

title: Simplified Model Predicts Binder Behavior in Sand Mold Printing abstract: Binder jetting is a crucial process in additive manufacturing (AM) and is widely used in sand mold casting. This study explores the challenges of simulating binder droplets in ANSYS Fluent, including complexity and computational time. To overcome these challenges, we propose a geometric approach that models the binder droplet as a circular shape instead of an actual droplet. Additionally, the dynamic mesh feature is employed to transform the initial boundary condition into a wall condition at a specified time interval (Δt). This simplified approach eliminates the need to simulate actual droplets, leading to significant computational resource and time savings. By adopting this geometric approach, we can accurately predict the diffusion and penetration behavior of binder droplets with varying materials and volumes in porous media with different porosities. Through data analysis, it was found that the main variables affecting the diffusion diameter and penetration depth are binder volume and porosity. The successful implementation of this simplified model enables researchers and engineers to expedite the simulation of binder behavior, facilitating process optimization and enhancing the understanding of binder jetting technology in the field of additive manufacturing.

機器學習對铣削加工在全面生產維修最佳化之預測

title: 機器學習對铣削加工在全面生產維修最佳化之預測 abstract: 銑削是一種極為常見的加工方式,所以在銑削加工中如何把效率做到最高是現代加工的一大課題。本研究應用全面生產維修(TPM, Total Production Maintenance)概念來延長機台使用時間,使機台使用時間增長,維修停機時間縮短;會影響加工時長的原因有許多,例如:刀具壽命、切削轉速、切削深度、進刀量等,但如更換這些控制因子再去使用全因子實驗會花費太多時間與成本,所以本研究會先應用田口方法來優化數據,再使用倒傳遞類神經網路(BPN, Back Propagation Neural Network)以及支持向量回歸 (SVR, Support Vector Regression)來進行模型預測和比較,希望能在不耗費大量成本下找到最佳化加工參數,提高加工效率。近年來隨著人工智慧的崛起及演算法的進步, SVR 被廣泛應用在多種領域,因此本研究利用 SVR 與 BPN 來建模,對於銑削加工參數來預測出最佳的參考組合,利用 SVR 建模所需樣本少的特性,以田口方法中的直交表來減少實驗次數,使用建立好的 SVR 與 BPN 的最佳化預測模型進行運算、比較,進而找出適合的預測法,再以此最佳的預測模型進行全因子實驗找出最佳解。
