The paper presents a practical three-phase PWM
\r\ninverter suitable for low voltage, low rating energy efficient systems.
\r\nThe work in the paper is conducted with the view to establishing the
\r\nsignificance of the loss contribution from the PWM inverter in the
\r\ndetermination of the complete losses of a photovoltaic (PV) arraypowered
\r\ninduction motor drive water pumping system. Losses
\r\ninvestigated include; conduction and switching loss of the devices
\r\nand gate drive losses. It is found that the PWM inverter operates at a
\r\nreasonable variable efficiency that does not fall below 92%
\r\ndepending on the load. The results between the simulated and
\r\nexperimental results for the system with or without a maximum
\r\npower tracker (MPT) compares very well, within an acceptable range
