Iron losses of a linear generator for a hybrid vehicle concept

This publication deals with the calculation and the measurement of the iron losses in a linear generator. The linear generator is intended for use in a hybrid power train design for a vehicle. The system surrounding the linear generator and some parameters have an influence on the linear generator and its iron losses. They will be explained to achieve a fundamental understanding of the requirements and the resulting topology selection. Furthermore, the question if the iron losses from a linear generator can be calculated analytically and how exact they can be calculated will be discussed. The calculated values are compared with the values measured on a prototype to permit an assessment of the quality of the calculations.
