Abstract

The battery is an important part used to drive motors and instruments in electric cars, but the number of batteries used needs to be considered to adjust the required working voltage. If a three-phase induction motor is used to drive an electric car, a battery voltage of 326 Vdc is required which is then supplied to a three-phase inverter to 230 Vac which will then be used as a supply to a 3-phase induction motor. So that to decrease the number of batteries to be used in this study, a voltage booster system, namely the Ultra Step-Up Converter will be designed which functions to increase the working voltage of the battery which was originally 48Vdc until the output voltage of 326 Vdc is obtained which can be loaded up to 1.2 kW. This converter will be added with fuzzy logic control to control the output voltage so that it remains constant at 326 Vdc even though the voltage on the battery varies.

Abstract

In this paper, a bidirectional DC-DC converter for energy storage in the photovoltaic system has been designed and simulated on MATLAB Simulink. The bidirectional DC-DC converter can work in two modes, charge and discharge mode. The energy storage system will work to store energy into the battery when the power generation capacity is higher than load demand. Then, the energy stored in the battery will be used for the DC bus supply when the power generation capacity is lower than the load demand. To get a constant voltage on the high voltage side (DC bus voltage) and a constant current on the low voltage side (charging current), a PI controller is used. Simulations were carried out with 1,000 W/m2 irradiation to get the power generation higher than the load demand (charge mode) and 200 W/m2 irradiation to get the power generation lower than the load demand (discharge mode) with constant temperature of 25 °C. The test result shows that a bidirectional DC-DC converter can work in charge and discharge modes, which is shown by battery charging currents and the increase or decrease in battery voltage.

Abstract

Sliding Mode Control merupakan salah satu kontrol non-linear yang banyak digunakan karena kesederhanaan dalam penerapannya dan dapat diterapkan pada sistem linear maupun non-linear. Modulasi pada Sliding Mode Control dapat menggunakan histerisis maupun PWM. Penelitian ini menjelaskan desain Sliding Mode Control dengan modulasi PWM yang digunakan untuk mengatur kecepatan motor dc menggunakan buck converter. Desain Sliding Mode Control dimulai dengan pemodelan dinamis yang kemudian direpersentasikan dalam bentuk state-space. Tahapan pencarian existance condition dan equivalent control juga akan dibahas. Hasil desain kontrol diverifikasi secara simulasi menggunakan MATLAB/Simulink dan secara eksperimen.

Abstract

Motor BLDC populer di aplikasi alat elektronik dari rumah tangga ke industri karena beberapa kelebihan yang mereka miliki. Namun juga memiliki kekurangan dalam pemasangan sensor yang menyebabkan peningkatan biaya mengemudi motor. Dari masalah ini, penggunaan metode sensorless (menggunakan deteksi tegangan balik EMF) adalah solusi alternatif untuk menentukan pergantian inverter pada motor BLDC, juga menggunakan metode FOC untuk mengurangi kebisingan dan riak torsi pada motor dengan memanfaatkan kontrol PID untuk mempercepat dan menstabilkan kecepatan rotasi secara otomatis. Kinerja sistem telah diuji menggunakan Matlab. Hasil simulasi menunjukkan bahwa metode FOC menggunakan PID dapat meningkatkan respons sistem dinamis dan mengurangi nilai overshoot. Perubahan kecepatan dalam sistem ini telah berhasil mencapai set point 3000 rpm
