How power electronics components enable sustainable energy generation

Demand for reliable and green electricity generation from Renewable Energy Systems (RESs) has been increasing over the past few years. Huge efforts have been made by many countries to install renewables such as wind power, PhotoVoltaic (PV) power, hydropower, and biomass power. Among various renewable power systems, Wind Turbine System (WTS) and PV system technologies are still the most promising technologies, accounting for a large portion of renewable energy generation and are expected to expand further.

We are already living in a world of DC where 70% of the electricity is produced with the help of power electronics. Exponential growth of renewable energy has been enabled in recent years, only because of technological advances in ‘Power Electronics’ devices and their ability to control power flow. AstrolKWx is committed to a greener and cleaner world of energy and our PE components find their place in the various applications.

Semiconductors for renewable-energy applications

Semiconductors: the backbone of power electronics systems

Power semiconductor devices are the backbone of power electronic systems which also drives many important factors of renewable energy systems including cost, efficiency and reliability. The press-pack packaged Insulated Gate Bipolar Transistor (IGBT), module packaged Insulated Gate Bipolar Transistor (IGBT), and press-pack packaged Integrated Gate Commutated Thyristor (IGCT) will be the major driving forces for, amongst others, the next generation of wind power applications.

Resistors for renewable energy applications

Failure to install an electric brake, choosing the wrong brake size, or using insufficient control strategy can have serious consequences on wind turbine operations as well as its lifetime. The correct sizing of a braking system in wind turbines is crucial factor of consideration to achieve a safe and reliable system. Astrolkwx can help you choose from a wide range of Danotherm brake resistors to design a safe and robust system.

Semiconductors for hydrogen production

Hydrogen is considered as the world’s cleanest energy source and it is expected to play a key role in the decarbonization of various sectors. The development of electrolyzer power supplies capable of managing low DC voltage under megawatt-scale power levels is critical to this rapid development. Astrolkwx has a wide range of high power IGBT’s and IGCT’s that are an ideal choice for electrolyzer applications.

Supercapacitors for peak shaving in renewable energy applications

Supercapacitors can be used in wind power systems for peak shaving, in other words: to reduce high current fluctuations. They are a good choice due to their high current charge and discharge characteristics. Supercapacitors are extremely suitable for use in wind power applications because of their long lifetime. When the wind is strong, energy will be stored in the supercapacitor. When the wind speed changes, the supercapacitor will start discharging to smooth out the system’s output power, enabling a more efficient power output.

Astrolkwx is involed in many renewable energy projects. Thanks to our experience, technical knowledge and our extensive product portfolio of A brand products our technical specialists are available to help you choose the most efficient semiconductor or power resistor for your specific application.
