Modulation Control

We are developing a small compact electric vehicle for shopping purposes. In this study, we fabricated an experimental vehicle, that uses only six small rechargeable AA batteries (7.2 V, approximately 2 A·h) as an electric power source. The vehicle user can select between two driving positions: standing and sitting. A compact transmission with a 90-W DC motor and a speed controller that uses pulse width modulation control was designed as an actuating system. Running experiments were conducted to observe the performance of the fabricated vehicle on a flat floor in a gymnasium. The fabricated vehicle was able to operate for 52 min at a speed of 2.73 km/h. The getting-on and getting-off processes in the vehicle were repeated many times during shopping. The human leg strain while getting on and off the vehicle was investigated by electromyogram measurement. During the getting-on and getting-off processes in the vehicle, the myoelectric potential of the quadriceps increased in the sitting position but did not increase in the standing position. The experimental results show that a user suffers more strain in the sitting position than in the standing position.

Electrical Installation

Electricity is the most suitable and appropriate form of energy for modern human life, such as today, where electrical energy has a function that can provide a need or service for electric power obtained by consumers, with electricity human life becomes very pleasant. Television, lighting, traffic lights, all using electricity. So, electricity can be said as a form of technological results that are very vital in human life. With this activity, it is expected that the general public can and understand about safe electrical installation and handling, mitigation of electrical hazards that are not in accordance with PLN's standardization. So that electricity does not necessarily become a scapegoat every time there is a fire in the community, and the voltage system used in Indonesia is: single phase 220 V, and phase three 220/380 V with a frequency of 50 Hz. This voltage system is very influential and dangerous for human safety.

We have been jointly developing an on-board electric power source for MAGLEV trains by applying a 30kW generator for gas turbine hybrid passenger cars. Operating the generator on a test model apparatus simulating the generator installed in a MAGLEV train, we investigated its electrical and mechanical characteristics with the location close to superconducting coils. The effects of magnetic field on the generator’s characteristics are investigated and described in this paper. MAGLEV trains require about a 50kW on-board power supply per car. At present, we are designing a 50kW gas turbine generator on the basis of the 30kW gas turbine generator.
