A Carrier-Based PWM Strategy Providing Neutral-Point Voltage Oscillation Elimination for Multi-Phase Neutral Point Clamped 3-Level Inverter

A Carrier-Based PWM Strategy Providing Neutral-Point Voltage Oscillation Elimination for Multi-Phase Neutral Point Clamped 3-Level Inverter

General pulse width modulation (PWM) model for multi-phase neutral point (NP) clamped (NPC) 3-level inverter (3LI) is described. A novel PWM strategy for N -phase NPC 3LI with unconditional NP voltage balance is proposed as well as its carrier-based realization, in which PWM sequences are generated...
