In developing electric generator product from air conditioner condensing unit, the researcher found that there were 4 important factors including speed, installation distance, size and cross-sectional area of the fan and the test was conducted between 8.00-17.00 hours. The researcher collected the data and analyzed the test result and found that the best result in the test was to install the product at the distance of 10 cm by using an 18" fan in order to acquire the best voltage and the data were collected so that they could be implemented in developing such product in the future. การค้นคว้าอิสระ (วศ.ม.) -- มหาวิทยาลัยเทคโนโลยีราชมงคลพระนคร, 2564 Mon, 21 Aug 2023 00:00:00 GMT http://repository.rmutp.ac.th/handle/123456789/4135 2023-08-21T00:00:00Z http://repository.rmutp.ac.th/handle/123456789/4132 Constrution of portable DC to AC voltage converter Ruengmit, Prajak; ประจักษ์ เริงมิตร; RuenNgew, Nontakorn; นนทกร เรืองงิ้ว; Juikong, Alongkorn; อลงกรณ์ จุ้ยคง As the world's energy resources are currently insufficient to meet human needs, energy-saving and energy-efficient appliances have to be invented that are readily available and accessible to everyone. To have enough energy to meet human needs and to reduce the waste from the waste of energy resources each year to meet the demand for energy that can be produced by itself. This research presents the construction of a portable DC to AC voltage converter, or “Constrution of Portable DC to AC Voltage Converter,” which can be operated through a solar cell. By charging energy from the sun and storing energy at the battery. and can also bring electrical energy to use inside the pressure converter There is an inverter circuit that converts voltage from DC to AC so that AC power can be used in daily life. which has a lighting system, power socket, USB port and helps reduce electricity bills in the house and is convenient to carry From the experimental results of creating a portable DC to AC voltage converter, it can be used in daily life and saves electricity and is also clean energy from sunlight that does not cause pollution like a generator that uses oil. be a generator โครงงานพิเศษ (วศ.บ.) -- มหาวิทยาลัยเทคโนโลยีราชมงคลพระนคร, 2564 Mon, 21 Aug 2023 00:00:00 GMT http://repository.rmutp.ac.th/handle/123456789/4132 2023-08-21T00:00:00Z http://repository.rmutp.ac.th/handle/123456789/4131 Electric Bicycle with Solar Panels Chuchuey, Nitit; นิธิศ ชูช่วย; Hrimchum, Jirapat; จิรภัทร์ หริ่มฉ่ำ; kanthawil, Athicha; อธิชา การถวิล This project presents an electric bicycle equipped with Solar Cell, which will charge the battery with a solar panel. To be used to drive electric bicycles, electric bicycles can be powered by two systems that are powered by the user's cycling and from brushed DC motors from battery charging with solar panels, the test will be tested by charging the panel with a time interval that the output voltage value From the solar panel which time interval is closer to the actual panel at 24 volts and charged into the battery,to test whether the electric bike can actually be used by a test drive starting with a displacement speed of 10 and 20 km/h at a distance of 100 meters. Using experiments with weight sizes of 50, 60 and 70 kg respectively, it was found that electric bicycles can actually be used. However, the above project has been made into two parts. is the part that charges the battery from the solar panel and the second part is a separate electric bicycle. โครงงานพิเศษ (วศ.บ.) -- มหาวิทยาลัยเทคโนโลยีราชมงคลพระนคร, 2564 Mon, 21 Aug 2023 00:00:00 GMT http://repository.rmutp.ac.th/handle/123456789/4131 2023-08-21T00:00:00Z http://repository.rmutp.ac.th/handle/123456789/4130 Exercise bike generate electricity for ON-GRID Prapasrivorakul, Nuttavee; นัฐวีย์ ประภาศรีวรกุล; Thongkot, Theera; ธีระ ทองคต This Project presents electric bicycle. The structural feature is the use of the bicycle to be modified as it is designed to spin the rotor of the 5-phase magnetic line generator set and test the voltage distribution. The principle of operation of electric bicycles relies on the mechanical energy gained from cycling. The rotor consists of a series of permanent magnetic poles, intersecting with a stator consisting of a set of conductor coils, generating an AC voltage and converting it from AC to DC through a diode bridge to obtain DC voltage. To be connected to the boost converter to increase the output side pressure level to get the right voltage to charge a 12 volt battery. batteries. The test has been tested for cycling to generate electricity at a speed of 400 rpm while no-load has a voltage of 23.3 volt, and with a load per load and at a speed of 400 rpm, the voltage is 12.1 volt If the bicycle is cycled at an increased speed, the voltage and current will increase. In order to transmit electric power to the single-phase power system, an inverter is used to connect the single-phase power system to transmit to the single-phase power grid. โครงงานพิเศษ (วศ.บ.) -- มหาวิทยาลัยเทคโนโลยีราชมงคลพระนคร, 2564 Mon, 21 Aug 2023 00:00:00 GMT http://repository.rmutp.ac.th/handle/123456789/4130 2023-08-21T00:00:00Z
