Modeling and simulation of the linear generator PWM multilevel inverter

Abstract

The paper describes the design of the multilevel converter, which acts as a link between the output of linear generator and the load. In linear generator the o/p frequency varies from 25 to 50 Hz depends on the load. Due to that, it is not suitable for many applications, which use 50 Hz AC. The actual linear generator output voltage waveform as simulated is similar in shape to the output voltage design results. The transformer-less multilevel converter is able to convert from the distorted non-50 Hz AC waveform to 50 Hz purely sinusoidal AC voltage and current waveforms at modulated output voltage. Pspice simulation results are presented to verify the validity of the model.
