The Incremental Conductance method has been implemented in a microcontroller to control the switching of a buck converter. The converter is connected to a battery with a very large capacity, thus it can be assumed that the output voltage is constant. Assuming that the converter is ideal and that it operates in continuous conduction mode, which of the following alternatives is valid to increase the PV module's voltage? You may choose more than one option.

To keep the switching frequency constant and increase the duty cycle.

To keep the switching frequency constant and decrease the duty cycle.

To increase the switching frequency while keeping the duty cycle constant.

To decrease the switching frequency while keeping the duty cycle constant.

To keep the time the switch is closed constant and increase the switching frquency.

To keep the time the switch is closed constant and decrease the switching frquency.
