Analysis and design of a solar charge controller using cuk converter

This paper presents a scheme for transferring power from the photovoltaic (PV) modules to a battery using a solar charge controller based on a Cuk dc/dc converter. The converter is configured in parallel power transfer mode (PPT) to achieve higher efficiency. PWM control with maximum power point tracking algorithm is used to extract maximum power from the PV modules. Mathematical modelling and field test results using multi crystalline photovoltaic modules have been carried out to verify the effectiveness of the device.
