Performance analysis of Seven Level Inverter with Interleaved Boost Converter under phase disposition and Variable Frequency Inverted Sinusoidal PWM´s

This paper analyse the performance of Seven Level Inverter which is configured by means of capacitor selection circuit and an H- bridge inverter. Multicarrier Sinusoidal Phase Disposition Pulse Width Modulation (MCSPDPWM) and Variable Frequency Inverted Sinusoidal PWM technique (VFISPWM) are employed for analysing the Total Harmonic Distortion (THD) of the Seven Level output. The capacitor selection circuit converts the output of the Soft Switching Interleaved Boost Converter and solar source into three level direct current (DC) voltage and an H- bridge inverter further converts three level dc voltage to seven level alternating current (AC) voltage. The performance parameters like output voltage and efficiency of two different Soft Switching Interleaved Boost Converters are compared and analysed with the conventional Interleaved Boost Converter.
