Abstract
Perkembangan sistem energi terbarukan mendorong kebutuhan akan konverter daya yang mampu menghasilkan tegangan tinggi dengan efisiensi optimal dan kompleksitas rangkaian yang minimal. Penelitian ini bertujuan untuk merancang, mensimulasikan, dan mengimplementasikan Hybrid Quadratic Boost Converter (HQBC) dengan konfigurasi satu saklar aktif yang dapat mengonversi tegangan input sebesar 35 V menjadi sekitar 400 V pada sisi keluaran. Desain konverter mencakup perhitungan nilai komponen utama seperti induktor, kapasitor, dan beban resistif, serta penyusunan sistem kontrol berbasis Proportional-Integral (P-I) untuk menjaga kestabilan tegangan keluaran terhadap variasi beban. Simulasi dilakukan dalam kondisi open-loop dan closed-loop menggunakan perangkat lunak PSIM. Hasil simulasi menunjukkan bahwa HQBC mampu menghasilkan bentuk gelombang switching yang stabil dengan ripple arus dan tegangan yang masih dalam batas toleransi. Implementasi fisik dari sistem dilakukan melalui pemilihan komponen aktif dan pasif berdasarkan hasil perhitungan teoritis, kemudian dilakukan perakitan dan pengujian di Laboratorium Konversi Energi Listrik. Hasil pengujian menunjukkan adanya deviasi kecil antara hasil simulasi dan implementasi, yang disebabkan oleh resistansi parasitik, switching loss, dan toleransi komponen. Meskipun demikian, HQBC tetap menunjukkan efisiensi dan stabilitas yang baik dalam penguatan tegangan. Disarankan penggunaan rangkaian snubber untuk meredam lonjakan tegangan (voltage spike) pada saklar guna meningkatkan keandalan dan umur komponen daya. Penelitian ini membuktikan bahwa HQBC merupakan solusi konversi daya yang efisien, handal, dan aplikatif untuk berbagai kebutuhan sistem energi terbarukan maupun elektronik daya tegangan tinggi.

The development of renewable energy systems has driven the demand for power converters capable of delivering high voltage gain with optimal efficiency and minimal circuit complexity. This research aims to design, simulate, and implement a Hybrid Quadratic Boost Converter (HQBC) with a single active switch, capable of converting an input voltage of 35 V to approximately 400 V at the output. The converter design includes the calculation of key components such as inductors, capacitors, and resistive loads, along with the implementation of a Proportional-Integral (P-I) control system to maintain output voltage stability under varying load conditions. Simulations were conducted under both open-loop and closed-loop conditions using PSIM software. The simulation results demonstrate that the HQBC produces stable switching waveforms with current and voltage ripple within acceptable limits. The physical implementation involved selecting active and passive components based on theoretical calculations, followed by circuit assembly and testing at the Electrical Energy Conversion Laboratory. Experimental results revealed minor deviations from the simulation, attributed to parasitic resistances, switching losses, and component tolerances. Despite these non-idealities, the HQBC maintained good efficiency and voltage stability. The use of a snubber circuit is recommended to suppress voltage spikes across the switch, thereby improving the reliability and lifespan of power components. This study confirms that HQBC is an efficient, reliable, and practical solution for high voltage gain applications in renewable energy systems and power electronics.
