The utilization of an impedance network in power electronic applications overcame traditional two‐stage converters' drawbacks, including a dc‐dc and dc‐ac stage. A well‐designed impedance‐based converter shuns the necessity of multiple network stages that, in turn, enhance operational performance and reliability. The split source inverter (SSI) belongs to such a single‐stage system that consists of an impedance network with a voltage source inverter. The work's primary purpose is to explore the performance of grid‐connected SSI in the application of wind energy systems. A novel peak power tracking controller is proposed for the SSI‐based wind energy systems for tracking the maximum power available in the wind. The grid‐side controller's current regulator is modified to sense the intermittent wind's perturbation and to regulate the SSI output current. The theoretical analysis is validated by simulation, and different case studies are analyzed by considering the mutual effects of SSI and variable wind speed. A laboratory prototype is designed for the experimental investigation of the SSI that consists of a 5‐kVA three‐phase grid‐tied SSI and wind emulator prototype. A field‐programmable gate array (Xilinx) is used to program the control algorithm. Different test cases are analyzed experimentally to prove the robustness of the proposed controller.

“…So, the dc‐link voltage should revert to the recommended voltage to transfer the maximum power. The recommended or reference value of the dc‐link voltage regulator is given as [23, 24] :

V_{d c, r e f} \geq \frac{2 * V_{a b c, S S I}}{\sqrt{6} * m_{a b c}},

where

V_{a b c, S S I}

is the rms voltage of SSI and m

_{a b c}

is the modulation index of SSI.…”

In conventional grid‐tied renewable energy applications, the dc–dc converter is inevitable. An increased cost, size, and reduced efficiency are the demerits of incorporating a dc–dc converter. A recently introduced split source inverter (SSI) is capable to perform both dc–dc as well as dcac at a time. The main attractive controllable feature of SSI is its modulation index. By utilizing this parameter, an interleaved control structure is proposed for the SSI in grid‐tied photovoltaic applications. The main objectives of the work are to track peak power and to maintain a stabilized voltage across the dc‐link capacitor at a variable load and grid disturbances. The proposed peak power controller performs two important actions: (i) the peak power is traced at all irradiance and (ii) generates a duty cycle to enhance the dc‐link capacitor voltage. The proposed scheme is essentially investigated with simulation. To validate experimentally, a 1 KW photovoltaic system is integrated into a grid‐tied 10 kVA SSI prototype. A Xilinx based Spartan field‐programmable gate array (FPGA) is used to provide a control algorithm for the SSI. Few case studies at different conditions are performed and investigated. Experimental and simulation results are presented to prove the robustness of the control strategy.
