Comparison of new multilevel inverter topology with conventional topologies used for induction heating system

الملخص EN

In this article, a comparison of innovative multilevel inverter topology with standard topologies has been conducted.

the proposed single phase five level inverter topology has been used for induction heating system.

this suggested design generates five voltage levels with a fewer number of power switches.

this reduction in number of switches decreases the switching losses and the number of driving circuits and reduce the complexity of control circuit.

it also reduces the cost and size for the filter used.

analysis and comparison has been done among the conventional topologies (neutral clamped and cascade h-bridge multilevel inverters) with the proposed inverter topology.

the analysis includes the total harmonic distortion THD, efficiency and overall performance of the inverter systems.

the simulation and analysis have been done using MATLAB / SIMULINK.

the results show good performance for the proposed topology in comparison with the conventional topologies.
