Current fed switched inverter with improved modulation index

The paper proposes a new topology named Improved Current Fed Switched Inverter which is derived from the current fed switched inverter. The new topology improves the value of modulation index from its previous topology where the value of modulation index was restricted. The improved current fed switched inverter is suitable for the renewable applications as it draws continuous input current. This paper describes about the inverter for the UPS application. Pulse width modulation (PWM) control strategy is used for the proposed inverter. The MATLAB/ SIMULINK is used to simulate the inverter and the performance parameters are also presented in this paper.
