This paper proposed a novel single-stage square wave buck-boost inverter (SWBBI). The proposed inverter is designed by using dual buck-boost converters. The input DC voltage of the proposed inverter can be either stepped-down or stepped-up in square output voltage waveform depending on the duty-cycle applied for each buck-boost converter. This characteristic is not found in conventional voltage source inverter where the output voltage is always lower than the input DC voltage. The proposed inverter is analyzed by a series of simulations using MATLAB/Simulink as well as experiments by using different values of duty-cycle. A conclusion about the feasibility of the proposed inverter is given by comparing the simulation and experimental results.

Abstrak— Rangkaian multilevel boost converter memiliki prinsip kerja yang sama dengan boost converter konvensional namun rasio tegangan keluarannya lebih tinggi. Dimana tegangan keluaran dari multilevel boost converter ini akan digunakan sebagai catu daya untuk mengendalikan kecepatan putar motor arus searah (MAS). Kemudian akan dilakukan perbandingan antara tegangan keluaran multilevel boost converter dengan boost converter konvensional yang digunakan sebagai catu daya MAS. Pada penelitian ini nilai tegangan keluaran multilevel boost converter saat dihubungkan pada MAS dengan duty cycle 20% yaitu 80,3 volt dan MAS sudah mulai berputar dengan kecepatan 350 rpm. Sementara tegangan keluaran boost converter konvensional sebesar 39,4 volt namun MAS belum dapat berputar pada duty cycle 20% dan tegangan masukan yang sama yaitu 12,3 volt. Kemudian dilakukan penambahan beban MAS pada pengujian multilevel boost converter. Dimana semakin berat beban pada MAS maka torsinya akan meningkat. Dengan demikian perangkat multilevel boost converter dapat digunakan sebagai catu daya MAS untuk kendaraan listrik. Kata kunci: Multilevel boost converter, boost converter, motor arus searah Abstract—Multilevel boost converter circuit has the same working principle with conventional boost converter. Hence, the ratio of its output voltage is higher that will be used as power supply for controlling the rotational speed of MAS. Then, there will be comparison among the output voltage of multilevel boost converter and conventional boost converter which will be used as power supply of MAS. On this research, the output voltage value of multilevel boost converter which is connected with MAS at the duty cycle 20 % is 80,3 volt. Furthermore, it had rotated at the speed of 320 rpm. Meanwhile, the output voltage of boost converter conventional is 39,4 volt. On the contrary, MAS can not rotated at the duty cycle of 20 % with the same input voltage that will be 12,3 volt. Then, it will be added with load of MAS for multilevel boost converter testing. While the load of MAS is heavier, its torque will be increased too. Therefore, multilevel boost converter device can be used as power supply of MAS for electric vehicles. Keywords: Multilevel boost converter, boost converter, direct current motor

voltage sags represent the greatest threat to the sensitive loads of industrial consumers, the microprocessor based-loads, and any electrical sensitive components. In this paper, a special topology is proposed to mitigate deep and long duration sags by using a modified AC to AC boost converter with a new control method. A boost converter is redesigned with a single switch to produces an output voltage that is linearly proportional to the duty cycle of the switch. On the other hand, the proposed control system is based on introducing a mathematical model that relates the missing voltage to the duty cycle of the boost converter switch. The simulation results along with the system analysis are presented to confirm the effectiveness and feasibility of the proposed circuit.

Photo-voltaic (PV) power harvest can have decent efficiency when dealing with high power. When operating with a DC–DC boost converter during the low-power harvest, its efficiency and output voltage are degraded due to excessive losses in the converter components. The objective of this paper is to present a systematic approach to designing an efficient low-power photo-voltaic harvesting topology with an improved efficiency and output voltage. The proposed topology uses a boost converter with and extra inductor in recycled and synchro-recycled techniques in continuous current mode (CCM). By exploiting the non-linearity of the PV cell, it reduces the power loss and using the current stored in the second inductor, it enhances the output voltage and output power simultaneously. Further, by utilizing the Metal Oxide Silicon Field Effect Transistor’s (MOSFET) body diode as a switch, it maintains a minimum hardware, and introduces a negligible impact on the reliability. The test results of the proposed boost converters show that it achieves a decent power and output voltage. Theoretical and experimental results of the proposed topologies with a tested prototype are presented along with a strategy to maximize power and voltage conversion efficiencies and output voltage.
