A Study Development of a 100kW Power Generation System Inverter Using Scrapped Engine

The engines of large trucks and buses, which are the most widely used means of transportation in recent years, are improving their performance characteristics as they become larger. Depending on the vehicle’s lifespan and model age, more than 750,000 vehicles are scrapped every year, and the residual value of discarded vehicle engines is more than 50%. By developing an engine generator by recycling known remaining waste common rail (common rail direct injection engine) diesel engines, the performance is excellent while the manufacturing cost can be significantly reduced. In addition, after development, it is an engine that can be commercialized from industrial to home use. One of the main technologies used in recycling engines is inverter control technology. In the case of rotary inverters, there was no product that could be miniaturized while considering the durability, reliability, and economic feasibility of the system and enabling high-efficiency operation. It was an inverter study that was not optimized for the system. In this study, an inverter with characteristics suitable for waste engine generators was studied and applied to industrial sites.
