永久磁石同期発電機を用いた自転車ローラー練習台発電システムの開発

抄録

Locally generated electricity is becoming more popular as a result of global warming as well as natural hazards that cause power outages from primary electricity grids. In this research, a generator using bicycle roller for training was developed in order to achieve both carbon-free and locally generated electricity. In the previous research, a car alternator was used in the viewpoint of cost. However, the efficiency of which was under 20% at the low loads. Therefore, in this research, permanent magnet synchronous generator was used in order to improve its efficiency for local electricity generation. Permanent magnet synchronous generator is expected to have a higher efficiency because it doesn’t use electrical power at its rotor. The developed electricity generation control system consisted of a buck converter and a digital potentiometer. As a result, the efficiency of the system was improved by up to 16% from the efficiency of the system using car alternator in the previous research.
