their higher energy generation capabilities compared to onshore turbines. Additionally, they support good weather and aquatic conditions. The need for effective power conversion technologies makes it difficult to meet an aggressive Levelized Cost of Energy (LCOE) objective for offshore turbines. A combination system that combines a Permanent Magnet Synchronous Generator (PMSG) with a rectifier system can be used to overcome this problem. An active rectifier and numerous passive rectifiers make up the rectifier system. However, obtaining the requisite maximum power output is challenging due to the presence of uncontrollable passive rectifiers. This research suggests a unique Fuzzy Logic Controller (FLC)-based Maximum Power Point Tracking (MPPT) architecture to address this problem. The proposed method enables the acquisition of maximum power (MPPT) by using FLC to analyze the d-axis current generated. Utilizing MATLAB/Simulink, the proposed method's efficacy is assessed.
The power outputs of the Gamesa10X [3] and Halide X [4] wind turbines are around 10–12 MW. The constraints of present converter topologies make it difficult to create dependable electromechanical power conversion systems for these high-power-density, energy-efficient turbines. The primary difficulties are brought on by power electronics switches' low voltage/current ratings and increasing switching losses [5]. Currently, two-level pulse width modulation (PWM) and neutral-point-clamped converters are frequently used. The second strategy is chosen because it provides a most simple design and operating approach.

1. INTRODUCTION The movement of air or gases from one place to another that results from variations in pressure and temperature is known as wind. Utilising these winds successfully allows for the production of wind energy. Modern methods for harnessing wind energy as electricity have been introduced in recent years. Depending on the region, there are two types of wind energy: onshore wind energy and offshore wind energy. Onshore wind energy involves producing electricity from wind turbines that are situated on land. On the other side, offshore wind energy is produced by wind that travels across the ocean. Typically, offshore wind energy is created in the ocean.

The architecture for tracking power points comprises connecting power electronic devices in series and/or parallel to manage many megawatts of power. However, the unequal distribution of losses across the switches in these configurations makes them frequently unreliable, which increases failure in hotspot locations. A neutral-pointclamped topology is used to solve this problem, greatly reducing the peak voltage that may be delivered to each switch [6].
Wind energy is a clean, renewable energy source that has a lot of potential for diversifying the world's electricity supply. It is increasingly being used as a renewable energy source. In comparison to onshore wind energy, offshore wind energy offers the advantage of a more reliable and powerful wind spectrum. Furthermore, because offshore winds are milder, turbine fatigue is reduced and its usable life is increased. The great potential of this renewable energy source is demonstrated by the increasing installed capacity of offshore

Reducing the power rating of individual power converters is the goal of implementing a multiport generator. Utilizing just active rectifiers, which convert AC to DC, is one strategy. Permanent magnet synchronous generators (PMSGs)-based integrated generator-rectifier systems are a possibility, as depicted in Fig. 1 [7]. Rectifiers fitted to each port in
