To address this problem, the authors have proposed a DC-DC converter that can boost the low voltage of a single-cell solar cell to a voltage that is easy to use and can maximize the performance of an aesthet- ically designed solar cell(3)(Fig.3(b)). The circuit that drives a single solar cell presents several Fig.2.
So it is necessary to couple the PV array with a boost converter. Moreover our system is designed in such a way that with variation in load, the change in input voltage and power fed into the converter follows the open circuit characteristics of the PV array. Our system can be used to supply constant stepped up voltage to dc loads.
The static characteristics of the low-voltage start-up circuit are shown in Fig.20. The output voltage is maintained at 5V until the output power exceeds 0 to 12mW, and when the output power is increased from there, the output voltage de- creases. Therefore, the low-voltage start-up circuit can han- dle loads of up to 12mW.
The low-voltage start up circuit us- ing the RCC method, which consists of general and easily available parts, can be started with a low voltage of a single solar cell, and can output the power required for the control power supply of the DC-DC converter.
Also-called boost converter is including as one of the power electronic device. Due to the growing importance of the boost converter in technology, a detail study of boost converter is necessary to make an improvement for future technology. A good boost converter can make the technology more efficient in usage.
