“…Among these, the PV-based power generation models are the most efficient models due to the absence of fuel filling and minimum cost. 3 The operation of the renewable energy system is nonoptimal since the direct current (DC) output of the renewable energy generation and the battery energy storage system are directly connected together. The assurance of the optimal operation with the insertion of DC/DC converter in the suitable location is the major requirement for the renewable environment.…”

Summary High quality and reliability of distributed power systems (DPS) play the major role in the telecommunications, industries, and home applications. The controlling of bidirectional power flow with the varied input and output voltage is the major issue in the distributed power systems due to the low settling time and the harmonics generated in them. The control signal provided to the switching devices used in the DC‐DC converter topologies is responsible for controlling the power flow. This paper presents the enhanced controller that receives the feedback signal as the input and generates the pulses necessary for the switching devices in the converter. The modeling of the feedback signal with the feedback‐integrated transfer function (FITF) provides the pulse density‐modulation (PDM) pulses to the switching section. The DC‐DC converter uses the DPS as front end, and this is a microgrid system. The FITF‐PDM reduces the losses in the switches and improves the output voltage level of the isolated bidirectional DC‐DC converter with the minimum settling time. The employment of zero current transition (ZCT) with the FITF‐PDM pulses boosts up the input voltage level to control the bidirectional power flow. The variations in the pulse density with respect to the variations in the feedback signal (error signal) are responsible for the update of the controlling function. The proposed FITF‐PDM is processes in simulation and compared with the existing control structures in terms of regulation efficiency assures the effectiveness of proposed DC‐DC modeling in the real‐time applications.

“…Through better injection, the SAPF should be able to compensate harmonics optimally [25,26]. Numerous methods have been used to extract harmonics in past research works, which include d-q axis with Fourier (DQF) [27][28][29], instantaneous reactive power theory (p´q) theory [30], adaptive filters [31], wavelet [32], synchronous reference frame (SRF) [33], synchronous detection [34], artificial neural network (ANN) [35], and many more.…”

This paper presents improvement of a harmonics extraction algorithm, known as the fundamental active current (FAC) adaptive linear element (ADALINE) neural network with the integration of photovoltaic (PV) to shunt active power filters (SAPFs) as active current source. Active PV injection in SAPFs should reduce dependency on grid supply current to supply the system. In addition, with a better and faster harmonics extraction algorithm, the SAPF should perform well, especially under dynamic PV and load conditions. The role of the actual injection current from SAPF after connecting PVs will be evaluated, and the better effect of using FAC ADALINE will be confirmed. The proposed SAPF was simulated and evaluated in MATLAB/Simulink first. Then, an experimental laboratory prototype was also developed to be tested with a PV simulator (CHROMA 62100H-600S), and the algorithm was implemented using a TMS320F28335 Digital Signal Processor (DSP). From simulation and experimental results, significant improvements in terms of total harmonic distortion (THD), time response and reduction of source power from grid have successfully been verified and achieved.

“…ENEWABLE energy generation (REG) has been recognized as one of the most effective solutions to the increasingly serious energy crisis and environment pollution [1]- [2]. The output voltages of renewable energy sources, such as photovoltaic, fuel cell and so on, however, usually vary over a wide range with climate, weather and operation conditions.…”

This paper proposes a current-fed LLC resonant converter that is able to achieve high efficiency over a wide input voltage range. It is derived by integrating a two-phase interleaved Boost circuit and a full-bridge LLC circuit together by virtue of sharing the same full-bridge switching unit. Compared with conventional full-bridge LLC converter, the gain characteristic is improved in terms of both gain range and optimal operation area, fixed-frequency PWM control is employed to achieve output voltage regulation, and the input current ripple is minimized as well. The voltage across the turned-off primary-side switch can be always clamped by the bus voltage, reducing the switch voltage stress. Besides, its other distinct features, such as single-stage configuration, and soft switching for all switches also contribute to high power conversion efficiency. The operation principles are presented, and then the main characteristics regarding gain, input current ripple, and zero voltage switching (ZVS) considering the nonlinear output capacitance of MOSFET, are investigated and compared with conventional solutions. Also, the design procedure for some key parameters is presented, and two kinds of interleaved Boost integrated resonant converter topologies are generalized. Finally, experimental results of a converter prototype with 120-240V input and 24V/25A output verify all considerations.Index Terms-Current-fed converter, LLC resonant converter, fixed-frequency PWM control, wide voltage gain range. 0885-8993 (c)
