Abstract

This paper discusses the comprehensive design and implementation of a photovoltaic (PV) emulator hardware using a synchronous buck converter. The primary objective is to simulate the electrical characteristics of a real PV module under varying environmental conditions. The process involves detailed simulations carried out using MATLAB/Simulink software to evaluate the performance and accuracy of the emulator model. Various load values were tested to account for the impact of fluctuations in radiation and temperature. The accuracy of the emulator's output characteristics was validated by comparing them with the actual attributes of the SolarWorld Sun-module SW50 PV module. The final step involves constructing the hardware of the PV emulator using electronic components, with an Arduino Nano employed as the controller.

Abstract

Proses pendinginan klinker merupakan proses yang sangat penting, karena dapat mempengaruhi kualitas akhir dari produk semen. Proses pendinginan klinker di PT Semen Baturaja Tbk dilakukan di Grate cooler clinker yang dibantu dengan beberapa cooler fan. Kecepatan motor dalam menggerakkan cooler fan akan bervariasi bergantung pada letak motor cooler fan tersebut, sehingga diperlukan pengatur kecepatan dari motor untuk memvariasikan kecepatannya, yaitu menggunakan Variable Frequency Drive (VFD). Laporan kerja praktik ini bertujuan untuk mengetahui sistem kendali beserta respon sistem kecepatan motor cooler fan 55FN08MT01 pada grate cooler clinker menggunakan Variable Frequency Drive (VFD) di PT Semen Baturaja Tbk. Berdasarkan hasil pembahasan, diperoleh sistem pengendalian motor cooler fan 55FN08MT01 pada grate cooler clinker menggunakan mekanisme closed loop control. Selain itu, diperoleh bahwa laju aliran udara selalu dijaga pada nilai set point-nya yaitu ±13.500 m3/h walaupun tekanan udara pada undergrate selalu berubah-ubah sehingga dapat dikatakan sistem pengendaliannya sudah bekerja dengan baik.

Abstract

This paper presents the design and simulation of a high-efficiency electric vehicle (EV) charger that integrates a two-phase interleaved boost converter (IBC) with a phase-shifted full-bridge (PSFB) converter using MATLAB/Simulink. In contrast to existing studies that treat these converter stages independently, this work introduces a unified AC–DC–DC architecture that simultaneously minimizes input current ripple, improves DC-bus stability, and enables soft-switching operation for reduced switching losses. The values of the inductors and capacitors are derived analytically based on ripple constraints and switching frequency considerations, and example calculations are explicitly provided. Simulation results demonstrate that the proposed charger maintains a stable 600-V DC bus with less than 2% voltage ripple, delivers a controlled charging current of 100 A with 3 A ripple, and achieves an overall efficiency of 95%. These findings indicate that the integrated interleaved–PSFB topology provides superior conversion efficiency and power quality, making it a strong candidate for future EV fast-charging infrastructure.
