This paper presents a PWM current source converter and inverter fed induction motor drive system. The system includes photovoltaic (PV) arrays of which the generating power is utilized for the motor drive. The module of the PV arrays is connected to the dc link of the system by using the step-down chopper. The chopper contributes to obtain the maximum power of the PV module in any case of the quantity of the sunlight. The converter is operated by the PWM technique without a phase-shift control and accomplishes the bi-directional power flow for the utility with sinusoidal current. This paper gives the steady-state characteristics and the power relations for the variation of the sunlight quantity and for the changing of the motor load. The transient waveforms of the system operation are shown. The experimental results are compared with the theoretical ones that are calculated by employing the statespace methods. The results prove that the presented system offers good performance in the utilization of the PV generating power.
