Abstract

This paper addresses the comparative analysis of THD for conventional bridge configuration CSI with
multilevel CSI such as 5 level. Multilevel Current source inverter (CSI) is an attractive solution in solar PV systems.
Generally multilevel inverter produces the output by merging of DC voltages means by rising of DC voltages. Mostly the
line commutated inverter has square formed waveform of line current. So it has large extent of harmonic and produces
excess of heat but multilevel inverter gives the output current waveform which is almost sinusoidal in nature. This line
current has smaller amount of harmonics as compared to line commutated inverter. Here two PV sources are taken and
MPPT charge controller is used to extract maximum power from solar. The more applicable control and modulation
methods established for such type of inverters are sinusoidal pulse width modulation technique. All the different CSI’s
are simulated in MATLAB with a load of 1HP as an single phase induction motor.
