In this work, the maximum power point (MPP) of a photovoltaic (PV) array utilized as a source of electricity in standalone mode is tracked using a genetic algorithm (GA) as an optimization tool. The major objective of this work is to implement and regulate a six-phase induction motor (SPIM) powered by a centrifugal pump and fed by a perovskite solar array through a three-phase inverter. Perovskite solar cells are the most promising third-generation photovoltaic technology to replace silicon-based photovoltaic. These cells are made cheaply, at a low temperature, and efficiently. The outcomes are then investigated utilizing a SPIM scaler (v/f) closed-loop control. PID controllers are tuned to keep the motor speed aligned with the reference value. The transformer's six-phase secondary is linked to an LC filter to reduce the voltage and current waveform ripple. A test setup was created and installed to investigate the potential of controlling the SPIM fed via a three-to-six-phase transformer. The findings showed that the area needed for the plates when utilizing perovskite solar cells is just 14 % of what it would be if a silicon-based solar array were used for the identical purpose. Perovskite solar cells' tiny surface area helps to prevent partial shading and lower costs. It was discovered that the suggested method works well for powering SPIM from a three-phase source.

“…There are power switches, S ଵ , S ଷ , …., S , that control the output voltage and power flow of the converter. Based on the number of input sources, working restrictions are applied to the circuit; and to simply the circuit, the branch with unidirectional switches, MOSFETs and diodes is converted into a single diode (S ଵ ) and a MOSFET (D ଶ ); otherwise, we can add D ଵ in S ଵ branch and S ଶ in D ଶ branch to rectify the restrictions [14].…”

“…2) is adopted. The SI-MISO DC-DC converter only has one inductor, and the inductor is the only path for power to flow through all ports, thereby achieving high power density and reducing the overall volume and weight of the converter [14]. Current sharing while simultaneously regulating the output voltage is one of the main challenges in the design of multi-input converters.…”

“…Many linear and non-linear methods are available to control multi-input converters, each with advantages and disadvantages. In [1], [14], and [15], a decoupling network is introduced to change a multivariable/input system into multiple SISO systems, but the MPPT cannot be used, and a system with a high number of inputs becomes very complicated and unstable. Other methods to control MIMO converters are proposed in [16] and [17], but they are complicated, and also do not have the MPPT.…”

In this paper, a single-inductor multi-input single-output (SI-MISO) DC-DC boost converter is used for solar photovoltaic (PV) systems in DC or AC grids. The converter with N number of inputs combines energy from PV panels along with fuel cells (FCs) to maintain stability. By implementing a new switching algorithm in the converter, the output voltage of the converter and the power absorbed from each source can be controlled independently, resulting in a simple and unique controller. In addition, the multivariable control system can be controlled as N number of single-input single-output (SISO) systems without any delay between switches due to the small-signal model of the converter and the proposed proportional-integral-derivative (PID) cascade control scheme. For each PV source, an independent maximum power point tracking (MPPT) algorithm can be employed, and the current sharing among different sources can be achieved independently. The converter's operating modes and the designed controller are present in the paper. Experimental results using a 100-W prototype converter validate the accuracy and efficiency of the proposed control scheme.INDEX TERMS Multi-input single-output DC-DC converter, photovoltaic systems, proportional-integralderivative (PID) cascade control, renewable energy.

The multiple‐input and multiple‐output (MIMO) DC–DC converters offer various advantages such as improved efficiency and reduced component count. However, the preference of these converters over other types of converters is dependent on the specific application and requirements. Various types of boost‐derived MIMO DC–DC converters are discussed in the literature. However, these converters are either nonisolated or isolated types. In the paper, a MIMO‐based cascaded boost hybrid interlink converter (CBHIC) has been proposed. The proposed converter includes four DC–DC boost converters that are supplied power by two input DC sources. The boosted DC output of these converters can be used independently or in a cascaded manner depending upon the requirement of the load. Further, the cascaded action of these four boost converters leads to the production of two high‐frequency AC outputs. By using bridge rectifiers and high‐frequency transformers, high‐frequency AC voltages are converted into DC. Therefore, two isolated DC output voltages can be achieved using CBHIC. The complementary operation of the cascaded boost converters results in reduction of source current ripples. The design, operating modes, and performance evaluation of the proposed CBHIC have been included in the paper. To validate the efficacy of the proposed CBHIC, a lab prototype of 400 W is prepared. The rms value of high‐frequency AC output voltage at each is isolated port is 141 V. The CBHIC exhibits an efficiency of 94.3 at 400 W. The operation of the converter during voltage control mode is further explored and its dynamic response is studies with the help of experimental results. The obtained simulation and experimental results validate the effectiveness of the proposed converter.
