Design and Prototyping of Inverter for BLDC Speed Control

Nowadays, fossil-fueled vehicles have caused many environmental problems, so that in the future electric vehicles will become the main substitute as a means of transportation, especially for short-distance light transportation. Thus, the development of electric vehicles is very relevant to be developed. However, on electric vehicles on the market, the control system used is less than optimal to respond to the load given to electric vehicles, resulting in a decrease in performance and waste of electrical energy. In this research, the design and prototyping of inverter for Brushless Direct Current (BLDC) speed control is proposed. The driver used is the Non-Isolated Gate Driver (NIGD) system that uses the IR2104 IC driver and IRFZ44N MOSFET switching power. As a prototype, a 9.6 W BLDC motor was used, equipped with a hall sensor for detection of rotational speed controlled by an Arduino microcontroller and monitored by Blynk. The results achieved are that the system can control the rotation of the motor and stabilize when there is a change in load disturbance, averaged in 30 seconds. The efficiency of the no-load system reaches 88.45% and in very heavy loading conditions it reaches 82.84%.
