Single Phase Inverter, MOSFET


This paper deals with the basic theory of a Pulse Width Modulated Inverter. its Simulink modelling, estimating various designing parameters and various instabilities. The project will be commenced by a basic accepting of the circuitry of the SPWM Inverter, the components used in its design and the reason for choose such components in this circuitry. Controlled rectifiers have a wide range of applications, In this paper, a new topology, based on the H-bridge designed with IGBTs midpoint grounding by sequence diode switching is proposed (NPC). In this topology without use ac bypass circuit consisting of a diode rectifier and a switch with clamping to the dc midpoint we can achieve the improvement in efficiency while conversion and low leakage current. The topology is simulated and experimentally validated, and a comparison with other existing topologies is performed. High conversion efficiency and low leakage current are verified. The proposed topology is verified using MATLAB and the all results are validated.
