A High Step Up Boost PFC as the Half Bridge Inverter for the High Efficiency DC-DC Multilevel Converter in Power Supply Unit

This project present advanced configuration for Symmetric multilevel voltage source inverter is p roposed. The Authority of the proposed inverter versus the conventional Cascaded H-bridge inverter and the most recently introduced ones, is verified with provided comparisons. The proposed Inverter is able to generate the desired voltage levels using a Lower number of circuit devices including power semi-conductor Switches and related gate driver circuits of switches. This modular structure uses reduced number of devices, including its power semiconductor switches and gate driver circuits of switches. As a result, the total cost is considerably reduced and the control scheme gets Simpler. Moreover, reduced amount of on-state switches in the Suggested configuration decreases voltage drops even, the suggested multilevel Inverter has the lowest amount of power losses. Finally simulation and experimental results are compared with each other and the provided comparison shows that the obtained results are in good Agreements.
