“…Overall, the discrete P&O delivered on average 11.84% less energy to the load. The discrete IC had much better performance, yielding on average just 1.69% lower energy capture [10]. For these reasons, the IC method was chosen to be implemented for the hardware prototype.…”

“…An outer voltage control loop was used to regulate the two output capacitor voltages. Regulating the two output capacitor voltages independently, rather than attempting to regulate the full DC link voltage, has been shown to yield improved performance for a PV input source under low irradiance operating conditions [10].…”

Abstract-This paper provides an experimental evaluation of a four phase Floating Interleaved Boost Converter for a photovoltaic power system application. This converter offers improved efficiency and voltage gain, while having lower input current ripple than other DC-DC boost converters. A dual loop, discrete, linear feedback was developed to regulate inductor currents and output capacitor voltages. Maximum Power Point Tracking capability was included. Results of all control functions were used to validate the control development, and point to areas for further improvement.

“…But requirements in renewable energy applications like size, weight and cost makes transformerless converters a more appropriate choice. Because of the capability of a boost converter to supply output voltage more than the input voltage, it is more feasible to be used in renewable energy applications .…”

The rising cost of fossil fuels, their high depleting rate and issues regarding environmental pollution have brought the attention of the researchers towards renewable energy technologies. Different renewable energy resources like wind turbines, fuel cells and solar cells are connected to DC micro grid through controllable power electronic converters. In presence of these diverse generation units, robust controllers are required to ensure good power quality and to regulate grid voltage. This paper presents a sliding mode control based methodology to address the above mentioned challenges. The proposed technique keeps the switching frequency constant so that electromagnetic compatibility (EMC) issues can be solved with conventional filter design. Parallel operation of converter in DC micro gird is considered. Chattering reduction and power quality improvement by harmonic cancellation is proposed. A scaled down hardware for unregulated 11.5 V to 17.5 V input and 24V output is designed and tested.The experimental results show good performance of the controller under different loads and uncertain input voltage conditions. Moreover, the results show the robustness of the closed loop system to sudden variations in load conditions. Furthermore, a significant improvement in power quality is achieved by harmonic cancellation of chattering in the output of the converters.

“…photovoltaic source) such as reduced input current ripple, high energy efficiency, compactness and high voltage ratio. For this reason, this topology is particularly fit for FC and photovoltaic applications where a high voltage ratio and low input current ripple are required [28,47,48], since FCs and photovoltaic sources produce an unregulated low-level DC voltage. In spite of the presence of natural redundancy, fault-tolerance has not been investigated yet [45e47,49].…”

Power switch failures tolerance and remedial strategies of a 4-leg floating interleaved DC/DC boost converter for photovoltaic/fuel cell applications

In recent years, many researchers have proposed new DC/DC converters in order to meet the fuel cell requirements. The reliability of these DC/DC converters is crucial in order to guarantee the availability of fuel cell systems. In these converters, power switches ranked the most fragile components. In order to enhance the reliability of DC/DC converters, fuel cell systems have to include fault-tolerant topologies. Usually, dynamic redundancy is employed to make a fault-tolerant converter. Despite this kind of converter allows ensuring a continuity of service in case of faults, the use of dynamic redundancy gets back to increase the complexity of the converter. In order to cope with reliability expectations in DC/DC converters, floating interleaved boost converters seem to be the best solution. Indeed, they have much to offer for fuel cells and DC renewable energy sources (i.e. photovoltaic system), including reduced input current ripple and reliability in case of faults. Despite the offered benefits of this topology, operating degraded modes lead up to undesirable effects such as electrical overstress on components and input current ripple increasing. The aim of this paper is to carry out a thorough analysis of these undesirable effects and to propose remedial strategies to minimize them.
