| Abstract | ||||
| In this paper the theoretical and experimental investigations for both steady-state and dynamic operation of dc-dc Cuk converter powered a separately excited dc motor are presented. The analysis is extended to the photovoltaic generator supply. The effect of duty ratio for different irradiation levels on the motor performance is obtained. The relation between solar irradiation level and converter duty ratio to ensure maximum energy utilization is given. The maximum photovoltaic generator can be obtained by adjusting the converter duty ratio for certain irradiation levels with a pump load. The proposed system can be utilized in spray irrigation and green house water supply management. | ||||
