Abstract
Development of Pulse Width Modulation (PWM) methods for dual-inverter fed Open-end Winding (OeW) five-phase motor drive is considerably challenging due to availability of a huge number of voltage space vectors and existence of multiple two- dimensional planes. The available PWM schemes were developed using decoupled technique that divides the voltage references into both inverters to reduce complexity. This paper discusses a novel PWM based on Decomposition scheme for dual-inverter OeW five-phase drive with DC-link voltage ratio of 2 : 1. The PWM scheme works at three operation modes. At 1.05 ≤ M < 0.7, inverter 1 is modulated at fundamental switching frequency while inverter 2 operates in PWM mode. At 0.7 ≤ M < 0.35, inverter 1 operates in 180° mode and inverter 2 in PWM mode. At M ≤ 0.35, only inverter 1 operates in PWM mode while inverter 2 locked at zero switching vector (00000 or 11111), reverting the system into single side supply drive mode. The developed PWM scheme is verified using MATLAB / Simulink and the performance is compared with three PWM methods. Simulation results show excellent performance of the proposed PWM scheme. The quality of inverter output voltages improves significantly over three PWM methods. It is also reveals that the smoother motor torque is achieved especially for M < 0.7. Further, the THD of motor current also improves especially for M > 0.35 compared with the URS PWM schemes and for M < 0.7 compared with the three-level decomposition PWM scheme
