In an era where technology reigns supreme, the thirst for power seems unquenchable. From the rise of high-speed computing to the electrification of transportation, the demand for energy is skyrocketing. But as the world races towards a greener future, the challenge lies in meeting these demands sustainably. Let's delve into the dynamics of this power surge and the innovative solutions emerging to address it.
The growth of computing power is staggering. By 2030, computers alone are projected to consume 3,000 Terawatt-hours (TWh) of electricity, a significant 15x leap from the 200 TWh consumed in 2016. Faster processing necessitates lower voltages and higher currents, with some systems drawing over 1000 Amperes (A) of current. Consequently, data centers, already accounting for 2% of global electricity consumption, face mounting regulatory pressure to enhance energy efficiency. While customers are demanding higher energy density.
The advent of high-speed AI further increases the strain on resources. With AI systems desiring ultra-low voltages (~1V) and extremely high currents (~1000A), data centers anticipate an 80% spike in resource allocation between 2023 and 2030. Regulatory frameworks such as Energy Star Certification and ISO 50001 impose stringent standards, compelling data centers to embrace sustainable practices. Würth Elektronik is working on a new inductor series to meet these needs.
Electric vehicles (EVs) spearhead the electrification revolution, demanding faster charging capabilities. Voltages exceeding 1.2 kilovolts (kV) and currents surpassing 100A will become increasingly common, necessitating a new infrastructure to support widespread adoption. Beyond cars, electric variants of buses, trucks, and large machinery intensify the need for scalable charging solutions.

The growth of energy storage, primarily driven by battery technologies, underscores the shift towards renewable energy sources. Inverters play a pivotal role in converting stored DC energy to usable AC, with advancements in solar inverters facilitating the integration of photovoltaic systems. Optimization of these systems will take real time monitoring and adjustment, such as found in battery management systems, thermal management, and current sensing. Emerging battery technologies and inverters are pivotal in advancing climate mitigation efforts.
Traditional technologies struggle to scale to the frequency, voltage, and current demands of modern power systems. Gallium Nitride (GaN) and Silicon Carbide (SiC) technologies offer higher switching speeds and voltages, enabling the development of more efficient power solutions. SiC, with its superior breakdown voltages, emerges as a promising option for higher voltage, high-power applications. You can learn more about our parts in this design done with onsemi.
As power levels soar, thermal management becomes paramount. Specialized thermal products and connectors, like those offered by REDCUBE, play a crucial role in dissipating heat and ensuring reliable connectivity. Bi-directional power stages with Power Factor Correction (PFC) are replacing older topologies, while innovative production techniques enhance reliability and safety.
Traditional bobbin wound magnetics are ill-suited for higher currents and voltages. New techniques such as heavy copper bonding, Litz wire bonding, and multi-gapped magnetic structures offer enhanced performance and efficiency. Welding technologies and advanced potting materials further contribute to the evolution of power electronics. Stay tuned for some exciting developments in these areas.
As the world grapples with escalating energy demands, innovative solutions are essential for achieving sustainability. From data centers to transportation, the transition towards energy-efficient technologies is imperative. By harnessing the power of advanced materials, innovative electronics, and sustainable practices, we can pave the way for a greener and more resilient future.
