Hitachi Energy, Pakal Unveil Silicon Power Semiconductor for HV Modules
February 25, 2026 | PRNewswireEstimated reading time: 2 minutes
Hitachi Energy, a global leader in electrification, and Pakal Technologies, a cutting-edge innovator in silicon power semiconductor design, announced a collaboration to advance shared value creation and sustainable growth. Hitachi Energy will incorporate Pakal Technologies' groundbreaking Insulated Gate Turn-Off (Thyristor), IGTO(t)™, silicon power switch into its portfolio of market-leading high-voltage power modules, beginning with devices used in essential applications such as rail, renewables, energy storage, AI and data center infrastructure.
Semiconductors sit inside almost every critical system, forming the backbone of a stable and modern grid. The collaboration addresses one of the most significant challenges in large-scale electrification: reducing energy losses and improving overall efficiency in high-voltage power conversion. By combining Hitachi Energy's expertise in power module design with Pakal Technologies' IGTO(t) innovation – which delivers 30 percent lower losses compared to today's widely used devices – the collaboration aims to contribute to cumulative daily efficiency gains across energy infrastructure. Together, the companies intend to produce the highest performing ≥3.3 kV power semiconductor modules for Hitachi Energy to offer to its large and growing global customer base, delivering higher performance, lower operating costs, and greater long-term reliability across critical electrification projects.
"With a century-long legacy of in-house semiconductor manufacturing expertise and ongoing expansion, Hitachi Energy is committed to advancing innovation in power electronics. We are pleased to join forces with Pakal Technologies to incorporate its novel IGTO(t) within our semiconductor portfolio," said Niklas Persson, Managing Director of Hitachi Energy's Grid Integration business unit. "This collaboration represents over time an opportunity to strengthen the global energy ecosystem at its core."
"Pakal Technologies was founded to make power conversion simpler, better, and more efficient. Collaborating with Hitachi Energy is an honor and secures a long-term partner capable of scaling impact with us," said Ben Quinones, CEO of Pakal Technologies. "Having our IGTO(t) platform recognized by a company with Hitachi Energy's exceptional history for quality, reliability, and performance in the energy landscape ensures we can contribute to today's sprint toward the electrification era."
The IGTO(t) represents the first new high-voltage silicon power semiconductor since the IGBT was introduced in the 1980s. The IGTO(t) delivers 30 percent lower conduction losses at high current and temperature than IGBT, while maintaining compatibility with existing module architectures. At the system level, these performance advances enable higher power density, reduced thermal and cooling requirements, and materially improved energy efficiency.

Dan’s Biz Bookshelf: ‘Abundance: How We Build a Better Future’
05/07/2026 | Dan Beaulieu -- Column: Dan's Biz BookshelfEvery once in a while, a book comes along that doesn’t just make you think, it makes you sit up straighter and ask: Why aren’t we doing this better? "Abundance" is exactly that kind of book. When so much of our national conversation revolves around scarcity—housing, energy, infrastructure, and opportunity—authors Ezra Klein and Derek Thompson flip the script. They argue, persuasively and intelligently, that America’s real problem isn’t a lack of ideas. It’s a lack of execution.

Driving Innovation: Selecting the Right Laser Source
04/28/2026 | Simon Khesin -- Column: Driving InnovationWhen I first joined Schmoll Maschinen, I brought experience from almost every PCB process, except for laser. As I immersed myself in laser processing, I realized why it can seem so daunting to a newcomer. The complexity arises from three intersecting factors: A vast variety of laser sources: CO2, UV-nano, green-pico, UV-pico, IR-pico, and others; a diverse range of applications: Drilling, cutting, ablation, and more; and an extensive list of materials: These have vastly different absorption rates. Choosing the right machine or laser source is rarely trivial. Even for experienced engineers, answering "Which source is best?" requires examining the business's specific goals.
