This document presents the designing of a
MATLAB/Simulink block for predicting the input voltages of several DC/DC boost
converters. The systems that use renewable energy such as photovoltaic (PV), fuel
cells (FCs) generate low DC voltage. The DC/DC boost converters are necessary
for stepping up the low DC voltage which generated by PV and FCs. The DC/DC
boost converters with PV and FCs are controlled by some maximum power point
tracking (MPPT) that used input voltage and current, and the control methods
which use the feedforwarded input voltage. The voltage measuring in simulation
area can be done easily without any cost. However, the voltage sensing element
should be used for the experimental studies and it increases the cost and size
of the system. Therefore, a MATLAB/Simulink block was designed to eliminate
voltage sensing element for several DC/DC boost converters. The predicting process
of the proposed MATLAB/Simulink block was shown on the conventional DC/DC boost
converter for variable input voltages (60-100-80-120-40 V) in MATLAB/Simulink
environment. The simulation results are satisfactory. The proposed block can be
utilized for several DC/DC boost converters via digital signal processors
experimentally.
