Abstract :
The paper proposes and describes the design and operating principles of 5 levels voltage source inverter which acts as a link between the output of the linear generator and the load. The output frequency of the linear generator varies from 25 to 50 Hz depending on the load. Due to that, it is not suitable for many applications, which use 50 Hz ac. This inverter consists of 6 switches (two levels conventional inverter) which operate at the main line power frequency and another additional circuit consists of 3 switches which operate at double the line power frequency. A prototype has been designed and implemented. To asses the proposed inverter, it is compared with the conventional two level inverter with single switching inverter. Simulation and experimental results are presented to verify the validity of the model
