Does selective harmonic elimination technique in multilevel inverters completely eliminate some low order harmonics or some are only reduced?

I have a 13-level output staircase multilevel inverter. I applied the selective harmonic elimination using the Newton Raphson method to eliminate the 3rd, 5th, 7th, 9th, and 11th low order...

Why current THD is higher then voltage THD when connecting a 9-level inverter to a single phase motor?

I have designed a 9-level inverter which was used to derive a single-phase induction motor. when measuring the THD, I found that the current THD is higher than the voltage THD as shown in Figures...
