Nowadays Offshore wind is a rapidly growing renewable energy resource. Offshore wind is the one that blows from land towards the sea. Harvesting offshore energy requires multi megawatt wind turbines and high efficiency, high power density, and reliable power conversion systems to achieve a competitive Levelized Cost Of Electricity (LCOE). So AC-to-DC power conversion is essential in many emerging high-power applications, including electrified transportation and wind-power generation. Collecting electrical energy through a DC form allows the prime mover, such as a wind turbine or a gas turbine, to operate at variable speeds, enabling Maximum Power Point Tracking (MPPT) leading to improved thermal efficiency. Creating ac-to-dc conversion systems at megawatt power levels that exceed conventional solutions in terms of efficiency, reliability, and compactness has been my target. An integrated system utilizing one active and multiple passive rectifiers with a multiport permanent magnet synchronous generator is a promising alternative for an electromechanical power conversion system. Deployment of the integrated systems in offshore wind energy requires maximum power point tracking (MPPT) capability, which is challenging due to the presence of numerous uncontrolled passive rectifiers. This article shows feasibility of MPPT based on a finding that the active-rectifier d-axis current can control the total system output power. The MPPT capability opens up opportunities for the integrated systems in offshore wind applications.
