Abstract

In the framework of the development of a drive system used for propulsion in a hybrid electric vehicle (HEV), a 16-pole permanent magnet (PM) synchronous in wheel motor is used. HEV wheel motor system is designed to convert electrical power into mechanical torque on the wheel using AC voltage as a voltage source and supercapacitor as an energy storage, two level IGBT’s voltage source converters, and permanent magnet synchronous motor (PMSM). The purpose of this research is to simulate the suitability of 3300 µF capacitors in HEV systems with PLECS based on MATLAB / SIMULINK. The design of current controller, speed controller and HEV electrical model are discussed as components of a drive control. All components used in this study use predetermined data and parameters. The voltage, current and angular velocity of HEV wheel motors output were recorded. The simulation results show that with a constant current, the speed will decrease and the capacitor voltage will increase. PMSM is changed as a generator that stores electric current to super capacitors, which can store more energy with a short time to be charged. In this case it can be concluded that super capacitors are very suitable to be used in this system.

Abstract

Anodizing process is a process that aims to strengthen the natural protective layer of metals so that the metal becomes a material that is resistant to rust and scratch by using electrolyte solutions and strong DC currents that help the occurrence of chemical reactions. The anodizing process is strongly influenced by current and voltage, the greater the current and voltage, the thicker the oxide layer that occurs on the aluminum surface and the hardness (hardness) will also increase so that the material becomes rust resistant, scratch resistant and if given an organic coating easy to fade or peel off. Optimization of current and voltage on portable anodizing devices will add value to the quality (quality value) of these materials.
