TLDR
A high gain dc-ac inverter topology is presented, which can produce an instantaneous output voltage higher or lower than the input dc voltage without any intermediate power conversion stage or transformers.Abstract:
Normally, a two stage power conversion system is used to convert a low dc voltage to high amplitude ac voltage. These two stage power conversion systems are very bulky, more complex in control and less efficient, etc when they are used, especially for low input dc voltages. In this paper a high gain dc-ac inverter topology is presented, which can produce an instantaneous output voltage higher or lower than the input dc voltage without any intermediate power conversion stage or transformers. Coupled inductor is used in this circuit in order to achieve high gain. The two stage power conversion will be done in a single stage by this converter. The proposed topology posses several desirable features like high gain, less loss and less size etc. The various modes of operation and steady state analysis of the proposed topology are presented. The proposed topology is simulated using MATLAB/SIMULINK, simulation results are presented to validate the proposed idea.read more
