Abstract

Medium voltage transmission systems driven by a high power three-level inverter operating at low switching frequency can reduce switching losses of the power
device. This paper proposes a subsection synchronous current harmonic minimum pulse width modulation (CHMPWM) approach of neutral point clamped three-level (NPC-3L) inverter in low switching frequency operation. A subsection synchronous scheme is obtained with the theoretical calculation at the allowed maximum switching frequency. Genetic algorithm(GA) is used to get high-precision initial values. The expected switching angles are achieved with as sequential quadratic programming (SQP) algorithm. Validity of the theoretical analysis and superiority of CHMPWM are verified via simulation and experiments.

Key words： current harmonic minimum; low switching frequency; three-level inverter
