Abstract

The increasing cost of fuels that are widely used today have increased interest in the use of renewable energy. In this modern area the use of renewable energy such as photovoltaic (PV) cells is verry common. Photovoltaic cell use sunlight as an energy source. However, the intensity of sunlight will always change. This causes the photovoltaic cell output voltage to vary. Therefore, a boost converter is needed to produce a high gain. One of reaserchs them is to use the cascade method. However, this metode have low efficiency and cost a lot of money. One solution to this problem can be used a quadratic boost converter. However, the quadratic boost converter will produce a high voltage stress on the switch component. Therefore, one other method that can be used to solved this problem in this paper is to use a voltage lift cell on a quadratic boost converter. the way to do that is by using a duty cycle value that has a value range of 0.1-0.9 to get the best rating value from the switch and diode components in order to produce a high gain as expected and a small voltage stress on the switching component and diode.
