This paper presents, a low power stand-alone solar photovoltaic (PV) energy generating system with paralleled DC current mode along with FPGA. KY Boost Converter, a recent invention in the field of non-isolated DC-DC boost converter is identified for minimum voltage ripple. This KY boost converter is proposed by K.I.Hwu and Y.T.Yau. is a non-isolated DC-DC boost converter operating in CCM (Continuous Current Mode) with voltage conversion ratio of 1-plus D. The KY boost converter operates in CCM keeping the output current non-pulsating leading to reduced voltage stress across the output capacitor resulting low output voltage ripples in the order of few hundred mV. The use of KY converter is more efficient when compared to normal boost converter. Higher level of energy can be saved by using parallel operation. The parallel operation of power supply circuits, especially in applications with higher power demand, has several advantages. One of the most important aspects is to improve the system reliability and the operational redundancy by it. The design with these standard parallel converter modules influences the cost of development in a positive manner. The parallel operation of KY converter is designed using MATLAB.
