“…Compared to other mainstream dc-dc topologies, the DAB converter takes advantages of high power density, galvanic isolation, soft switching and bidirectional power flow [6], [7]; The solidstate transformer or smart transformer formed by two dc-ac converters and a dc-dc converter was proposed to replace the conventional 50/60 Hz transformer which links mediumvoltage (MV) stages and low-voltage (LV) ac stages in the future electrical grid [8], [9]. When the voltage conversion ratio is high, the modularization of converters becomes a popular way to cope with the problem of high voltage stress on the power semiconductors [10], [11]. With this consideration, the multilevel converter was proposed, which has the seriesconnected submodules on the arms and has benefits of high quality output voltage and current, high modularity and low stresses of switches [12].…”

The power electronics are supposed to be popularized in the electrical grid to facilitate the integration of renewable energy units, leading to a cleaner and more efficient electrical power distribution system. In addition, the modularity feature of power electronics enables the potential of high voltage/current conversion ratio to replace the conventional transformer in grid. As more power electronics are going to be added into the system, the system stability can be a main concern due to the nonlinear characteristic of power-electronic devices. Therefore, the stability-oriented modeling of power-electronic devices is always necessary for system integration. This paper investigates the impedance models of dual-active-bridge (DAB) based input-series output-parallel (ISOP) converters by considering the promising features of modular power electronics and the advantages of DAB converter. By applying the small-signal analysis methodology, the input impedance and output impedance of DAB-based ISOP converter are derived and validated in simulation and experiment. Based on the validated impedance models, the instability phenomenon can be accurately predicted at the source side and load side of converter respectively.

Sebagai penyedia jasa lalu lintas udara, operator bandar udara tentu perlu memberikan pelayanan yang maksimal. Unit pelayanan untuk mengelola tugas pengelolaan di bandara salah satunya adalah Apron Movement Control. Apron merupakan bagian dari bandar udara yang berfungsi sebagai tempat parking pesawat. Unit Apron Movement Control dalam melaksanakan ketertiban operasional agar tercapainya kegiatan dengan baik sesuai peraturan yang sudah ditetapkan dibantu oleh petugas magang, sehingga pentingnya pemahaman petugas magang mengenai fungsi marka, peraturan tentang marka, dan jenis-jenis marka dalam penerbangan. Penelitian ini bertujuan untuk mengetahui pemahaman petugas magang tentang marka di sisi Bandar Udara Adi Soemarmo Surakarta. Penelitian ini merupakan penelitian kualitatif dengan teknik pengumpulan data menggunakan observasi, wawancara, self appraisal, dan dokumentasi. Responden dalam penelitian ini berjumlah tujuh orang yaitu petugas magang di unit Apron Movement Control di Bandar Udara Adi Soemarmo Surakarta. Hasil penelitian ini menunjukkan bahwa beberapa petugas magang mengenai marka cukup paham dan menguasai terkait penempatan parking stand pesawat udara, tetapi ada beberapa petugas magang yang masih kurang dan bingung dalam pemahaman terkait penempatan parking stand untuk pesawat udara. Hal tersebut karena tidak adanya bantuan visual di dalam ruangan Apron Movement Control. Solusi yang dilakukan yaitu petugas magang melakukan inspeksi langsung ke apron untuk mengetahui letak dan bentuk marka parking stand tersebut.
