Feedback Control of the DC/DC Converters for PV Source Emulation

Part of the Green Energy and Technology book series (GREEN)


This chapter deals with the design and realization of a DC/DC converter for PV emulating purposes. Once the appropriate model has been chosen, the I–V relationship is used to control a DC/DC converter whose output reproduces the behavior of the PV generator. This chapter contains the fundamentals of feedback control and an example of PV emulator design, realized by a buck converter. In particular, both the model and the converter are first simulated in Matlab-Plecs® environment, then the practical implementation of the control algorithm on a DSP board, and the overall PV emulator equipment is illustrated and finally the experimental results are presented.
