Lujara PY - 2015/5/ TI - Three Phase PWM Inverter for Low Rating Energy Efficient Systems T2 - International Journal of Energy and Power Engineering SP - 422 EP - 429 VL - 9 SN - 1307-6892 UR - https://publications.waset.org/pdf/10000828 PU - World Academy of Science, Engineering and Technology NX - Open Science Index 100, 2015 N2 - The paper presents a practical three-phase PWM inverter suitable for low voltage, low rating energy efficient systems. The work in the paper is conducted with the view to establishing the significance of the loss contribution from the PWM inverter in the determination of the complete losses of a photovoltaic (PV) arraypowered induction motor drive water pumping system. Losses investigated include; conduction and switching loss of the devices and gate drive losses. It is found that the PWM inverter operates at a reasonable variable efficiency that does not fall below 92% depending on the load. The results between the simulated and experimental results for the system with or without a maximum power tracker (MPT) compares very well, within an acceptable range of 2% margin. ER -
