Abstract

Switching Converter adalah salah satu sirkuit switching yang sering digunakan dalam sirkuit daya. Konverter digunakan dalam sistem fotovoltaik untuk menyesuaikan titik daya maksimum. Salah satu konverter umum adalah Boost Converter. Boost Converter terdiri dari komponen yang tidak sepenuhnya ideal. Beberapa komponen parasit ada di samping komponen utama. Sebagian besar analisis sirkuit tidak mempertimbangkan untuk sistem fotovoltaik. SIS ini mempelajari efek konverter peningkatan non-ideal ke sistem fotovoltaik. Analisis simbolis dilakukan untuk menemukan efek dari non-idealitas terhadap daya. Simulasi numerik diterapkan untuk menganalisis dan menunjukkan bahwa kembali adalah daya maksimal yang berbeda antara modul dan beban fotovoltaik. Fur rmore, sistem kontrol harus dirancang untuk mengatasi masalah perbedaan. Karena target nyata adalah daya maksimal di sisi beban, pengontrol dirancang berdasarkan respons steady-state dari daya beban. Prosedur desain didasarkan pada ory dari kontrol mode geser nonlinear. UU kontrol yang diusulkan disimulasikan dalam MATLAB untuk mengamati kinerja pengontrol. Simulasi menunjukkan bahwa pengontrol yang diusulkan menjamin daya muatan yang lebih tinggi daripada pengontrol konvensional.

English Abstract

Switching converter is one of switching circuit which is often used in power circuit. converter is utilized in photovoltaic system to adjust maximum power point. One of general converters is boost converter. Boost converter consists of components that are not completely ideal. Some parasitic components exist beside main component. Most of circuit analyses had not considered effect to photovoltaic system. This sis studied effect of non-ideal boost converter to photovoltaic system. Symbolic analysis was performed to find effect of non-ideality to power. Numerical simulation was applied to analyze and show that re was a different maximal power between photovoltaic module and load. Fur rmore, a control system should be designed to overcome difference problem. Since real target was maximal power at load side, controller was designed based on steady-state response of load power. Design procedure was based on ory of nonlinear sliding mode control. proposed control law was simulated in MATLAB to observe controller performance. simulation showed that proposed controller guaranteed higher load power than conventional controller.
