“…Generator system is widely used as an emergency power supply in various facilities, islands, aircraft, and ships [1,2]. Recently, different types of generators are researched for the utilisation in renewable energy systems, such as wind-turbine generation, tidal power generation, and wave power generation [3]. The biggest markets for generator systems are the emergency generators to counteract power outages, generators for ships, and alternators in vehicles.…”

This study presents the design and control scheme of a self-excited 10 kW-380 V synchronous generator using a permanent magnet (PM) exciter. The PM exciter generates field current according to the engine speed to maintain the output voltage of the proposed generator so that constant voltage can be produced regardless of the speed. For the direct control the field winding current, a current controller is designed and embedded on the shaft. In the proposed generator, the reference current is determined by an external voltage controller and it is transferred to the rotating embedded current controller using an infrared (IR) transmitter and receiver aligned to the shaft. In order to improve control performance, the reference field current is controlled by the actual frequency of the generator based on the reference frequency. Therefore, when the engine speed is fluctuating due to engine governor dynamics, the frequency-based field current can maintain the output voltage constant because of the compensation term for speed variations. In the compared experimental results between the conventional generator with winding type exciter and the proposed generator system, both dynamic performance and operating efficiency of the proposed system are improved.
