Elimination of speed ripples in a cogeneration system with stirling engine by an electromagnetic coupling

Multilevel energy conversion system, as cogeneration and trigeneration systems, has been carrying out an important attention on the least years due to the advancement in different technologies. In this paper is presented the solution used in the order to avoid the speed ripples of Stirling engine in a cogeneration system. In this sense, in the topology of cogeneration system, it has been interfaced an induction coupling, which change the value of time constant. The numeric simulations performed in Matlab-Simulink environment, show the performed advantages of the proposed solution.
