Analyzes of Flyback DC-DC Converter for Submodule Level Maximum Power Point Tracking in Off-grid Photovoltaic Systems

Abstract

Submodule level
maximum power point tracking (MPPT) systems have become popular due to its
outstanding performance in partial shading conditions (PSCs) and basic
algorithm requirement. MPPT is realized by DC-DC converters. They are power
processing units between photovoltaic (PV) module and load. Among DC-DC
converter topologies, flyback is a proper choice since it can either increase
or decrease the voltage. Furthermore, power level is small in submodule level
MPPT applications. In this study, analyzes and power circuit design of flyback
converter for continuous conduction mode (CCM) are carried out firstly. Then, performance
of flyback converter on submodule level MPPT system and its superiority over
the module level MPPT is shown by using same converter topology and perturb and
observe (P&O) algorithm. In order to validate the superior performance of
submodule level MPPT, it is compared with module level MPPT in MATLAB/Simulink
environment. Results show that submodule level MPPT guarantees global MPPT in
any PSCs with any kind of basic MPPT algorithm. On the other hand, module level
MPPT fails in many PSCs with the same algorithm. According to simulation
results, submodule level MPPT generated more power by 61.2% in average than
module level MPPT systems in simulation studies.
