The ripple current increases with A d as expected. A trade off therefore exists between the magnitude of the ripple on the duty cycle and the effectiveness of the instrumentation to measure the maximum and minimum current and voltage ripple on the solar panel. In addition it is necessary to ensure that the inductor can deal with this extra ripple.
