In this paper, the authors propose a new scheme Pulse Width Modulation (PWM) to overcome low performances of conventional PWM control strategy in Asymmetric Cascaded Multi-Level Inverter (ACMLI). This scheme advance conventional Carrier-Based PWM (CBPWM) using triangle carrier in different amplitudes. By this scheme ACMLI can control by PWM that according to dc voltage amplitude used and finally the Total Harmonics Distortions (THD) can reduce to the settle standard. Simulation using Matlab Simulink used to verify the performance and result simulation shown than this proposed scheme can reach the goals.
