Abstract

Passenger boats are a means of transportation that is used to transport passengers to a destination. One of them is a boat for passengers to visit the religious tour of Sheikh Mudzakir's grave. The religious tourism location of Sheikh Mudzakir's grave is located about 2 km north of Blekok Island. However, this passenger boat still relies on fuel oil as fuel to drive the passenger boat's combustion engine. Research on electric boats was carried out by several students at Semarang University. This electric boat uses solar panel technology installed on it to harvest solar energy and convert it into electricity which is stored in batteries to move the boat. This electric boat uses a 3 Phase 1 HP 4 Pole electric motor that uses solar charge control and an inverter as a converter from 12 V DC to 380 V AC. Using a 3 Phase Electric Motor requires a large amount of electricity, because it requires electricity that must be converted to voltage. high, will result in high loss, so that the efficiency of battery use is relatively wasteful. The aim of this research is to carry out tests using a 4 kW 72 Volt BLDC Motor as an alternative solution to replace previous research which used a 3 Phase 1 HP Motor on an electric passenger boat. The results show that the motor rotation of a 4 kW 72 Volt BLDC motor tends to be greater than using a 3 Phase 1 HP electric motor and a 9 HP fuel engine, where previous research showed that the speed of an electric boat can only reach a maximum speed of 4.4 Knots at high mode gas level. , while using a 4 kW 72 Volt BLDC motor it can reach a speed of 8 Knots, which is a huge improvement. Very suitable for using a 4 kW 72 Volt BLDC motor on a 1GT electric boat

Abstract

Photovoltaic (PV) systems frequently encounter low and fluctuating output voltages, which can significantly impede efficient energy utilization and necessitate more advanced power conversion solutions. Addressing this challenge, the study aims to develop a high-gain DC-DC converter topology that offers stable voltage regulation, making it suitable for PV applications. The proposed solution targets the essential need for substantial voltage boosting while maintaining reliable performance even under varying solar irradiance conditions. The core of the design is based on a Quadratic Boost Converter (QBC) integrated with Voltage Multiplier Cells (VMC), collectively referred to as QBC-VMC. This innovative configuration enhances the voltage gain capability compared to traditional converters. To ensure precise control of the output voltage, a Proportional-Integral (PI) controller is implemented. The system undergoes thorough analysis, including detailed modeling, simulation, and the design of its control structure, to optimize performance. The results demonstrate that the proposed converter can achieve a voltage gain of up to 12 times the input voltage. The PI controller effectively maintains a stable output voltage at approximately 600 V with a tolerable variation of ±0.7%. Additionally, the system exhibits an energy conversion efficiency approaching 81%, even under fluctuating irradiance conditions. This indicates a strong dynamic response and steady-state performance, essential for reliable PV operation. By integrating QBC-VMC with PI control, the proposed approach significantly enhances voltage stability and energy conversion efficiency. Overall, this system provides a promising solution for high-performance PV power systems, capable of delivering reliable power output under varying environmental conditions.
