Problem) A photovoltaic (PV) panel needs to be connected to the 24V DC bus. The output voltage of the PV panel varies as shown in Fig.PE_I. The maximum power point (MPP) of the PV panel for different irradiances is also shown in Fig. PE-1. A power electronic converter needs to be designed to keep the PV deliver the MPP with variations in irradiances. The switching frequency is 100kHz. a) Which topology should be used to implement this converter and why? b) What is the output voltage range of your selected converter? c) Calculate the minimum value of L so that the converter works in CCM over the whole operating range.
