Abstract

Suplai kualitas daya listrik yang baik merupakan elemen yang sangat dibutuhkan bagi peralatan listrik. Umumnya inverter konvensional menghasilkan THD tegangan dan arus yang cukup tinggi yang mana berpengaruh pada meningkatnya rugi-rugi akibat harmonisa sehingga efisiensi yang dihasilkan semakin turun. Oleh karena itu diusulkan sebuah sistem terdiri dari baterai sebagai sumber dc yang digunakan untuk mensuplai multilevel inverter yang merupakan salah satu jenis inverter yang memiliki bentuk gelombang tegangan maupun arus yang bertingkat. Multilevel inverter dimodulasi dengan metode Alternate Phase Opposition Disposition (APOD-PWM) yang mana teknik modulasi ini membutuhkan masing-masing dari empat bentuk sinyal pembawa untuk bentuk gelombang keluaran inverter tiga tingkat dengan masing-masing sinyal pembawa digeser fasanya sebesar 120˚ dari sinyal yang berdekatan secara bergantian. Dari data hasil pengujian, multilevel inverter 3 tingkat dapat mengubah 36 VDC  menjadi 15.6 Vrms AC yang kemudian dinaikkan tegangannya oleh trafo step-up menjadi 215 Vrms AC dengan persentase error 2.2%. Keluaran dari multilevel inverter tiga tingkat setelah melalui filter dengan beban lampu pijar 400 Watt menghasilkan THD tegangan sebesar 7,4% dan THD arus sebesar 7.6%.

Abstract

Autoped has become a popular alternative in environmentally friendly urban transportation. It uses batteries as the main power source to drive their electric motors. However, efficient and optimal battery usage is essential to maintain the performance and durability of autoped. This study aims to design a speed monitoring system for autoped using LiFePO4 batteries by considering variations in user loads. This monitoring system informs autoped drivers about the speed when used and battery usage. This electric autoped is equipped with a DC brushed motor with a specification of 24 Volt/500 Watt. The speed is measured using a metal proximity sensor that functions without direct contact, thus ensuring consistent measurements and reducing the risk of errors due to physical interaction. In addition, a load cell sensor with a maximum weight measurement of 100 kg is used to classify user's weight which is divided into three variations: 35-45 kg, 46-55 kg, and 56-65 kg. As the main energy source, this system uses a LiFePo4 battery with a specification of 24 Volt/36 Ah. The system was tested on a flat track on the campus, where the scooters were used to support environmentally friendly mobility around the campus area. This test ensured that the designed speed monitoring system was able to provide real-time data on scooter performance based on user weight, as well as support increased efficiency of battery energy use.
