“…Such an example was built by the University of Rome in 1996 with two inputs and a shared output [12]. This design, while novel for its time, struggles to regulate its output voltage effectively whenever one of the two input sources falls out of operation, which is due to large input voltage variation [13]. Several of the newer multiple-input converters rely on a time-multiplexing strategy for their source switch operation.…”

“…Instead of combining inputs electrically and sending them directly to the output, the converter combines input source magnetic flux terms and induces the magnetic core to provide a cleaner output. There are numerous benefits to this design including very high efficiency and reduced total harmonic distortion, however, these benefits come at the cost of using a large amount of components to assemble the design [13].…”

iv As power systems throughout the world continue to utilize DC infrastructure within distributed generation solutions and microgrid designs, an effective DC-DC interfacing power electronic device must be developed for managing power flow and power quality levels between a system's increasingly diversified array of sources and loads. DC-DC power electronic interfaces are continuing to gain increased attention throughout many distribution applications, including the information and communication technology (ICT), electric vehicle, and renewable generation industries.The research effort described herein explores the use of a multi-port DC-DC modular multilevel converter interfacing a dual-input connection of a 380 VDC system and a 42.9 VDC/ 40.7 A photovoltaic panel with a 96 VDC output resistive load. Ultracapacitors are used to power-buffer the input signal and in this application, the inherently intermittent solar panel output. This technology represents the merits of utilizing a singular interfacing device to consolidate the flows between joint generation and load, while maintaining stable output power using a modular energy storage solution.This work details the operation and control of the DC-DC converter and its moduleinterfaced power buffering solution, as well as provide design methodologies for the system described.

“…On the other hand, the integrated PV system-to-AC grid usually involves one DC-DC converter, employed to track the maximum power point of the PV system [11][12][13][14][15][16][17][18][19]. However, this DC-DC converter's switching itself prolonged the PV unit's response time, leading the PV system to include pulsating current harmonics [20][21][22][23][24].…”

Available photovoltaic (PV) systems show a prolonged transient response, when integrated into the power grid via active filters. On one hand, the conventional low-pass filter, employed within the integrated PV system, works with a large delay, particularly in the presence of system's low-order harmonics. On the other hand, the switching of the DC (direct current)-DC converters within PV units also prolongs the transient response of an integrated system, injecting harmonics and distortion through the PV-end current. This paper initially develops a wavelet-based low-pass filter to improve the transient response of the interconnected PV systems to grid lines. Further, a damped input filter is proposed within the PV system to address the raised converter's switching issue. Finally, Matlab/Simulink simulations validate the effectiveness of the proposed wavelet-based low-pass filter and damped input filter within an integrated PV system.

“…The perfect power supply does not reproduce ripple on the input current. Normally, power supplies are not perfect because the resistance of input produces rippled voltage and current curves at what time the input power has ripple [2], [3]. The photovoltaic source can be both a current and voltage source.…”

AbstractÑThis paper discusses the impact of fill factor on the input current ripple of the photovoltaic module and the loss effect on power extracted. Photovoltaic moduleÕs P-V curve produces exponential curve. The curvature of this curve indicates the fill factor of the particular cell, hence, by increasing the fill factor, the available extracted power increases. Yet, this paper states that losses due to photovoltaic current increases by increasing the fill factor.
