This paper introduces a selective harmonic elimination (SHE) PWM method based on neutral-point potential balancing applied to a three-level Photovoltaic NPC Inverter. The method combines the SHE with neutral-point potential balancing, and introduces a method based on multi-objective ant colony algorithm to solve the SHE-PWM non-linear equations. SHE-PWM control method of multi-objective ant colony algorithm considering about neutral-point potential balancing, there is no need to solve the initial value of the equation when solving the SHEPWM equations. Experimental results demonstrate the validity of SHE-PWM method based on neutral-point potential balancing.
