AI Server Power Supplies: GaN Adoption Criteria

Deciding whether to adopt GaN in AI server power supply design isn't solely based on it being "next-generation technology"; it requires confirming GaN's clear advantages over SiC and Si along the three axes of switching frequency, power density, and thermal design.

Chinese SiC Manufacturers: Selection Criteria

Many teams are internally divided on whether to adopt Chinese SiC manufacturers, with some voicing concerns about quality and others emphasizing the undeniable cost factor, but responding to this question with a simple "not adopting because it's Chinese" or "adopting because it's cheap" is too simplistic a judgment; what is being asked is how and what to verify.

Foundations for Power Semiconductor Supplier Evaluation

A design team preparing for high-volume production of EV inverters faced an initial hurdle in selecting SiC MOSFET suppliers: "We don't know which datasheets to compare." Simply juxtaposing spec sheets proved insufficient as measurement conditions altered the meaning of figures, and reliability data was presented in inconsistent formats across different companies.

Evaluating the Adoption of ROHM's 5th Generation SiC MOSFET

As the next generation of SiC MOSFETs emerges, many companies are asking, "We want to evaluate the 5th generation, but where do we start?" Considering Rohm's announced 4th generation features of low on-resistance (RonA) and high short-circuit withstand capability, evaluation of the 5th generation must go beyond device specifications alone, encompassing compatibility with protection circuits and thermal design considerations.

SiC and GaN Business Opportunities: Evaluation Criteria

SiC or GaN: The next-generation power semiconductor question, while frequently asked in the industry, is somewhat simplistic; though both are wide bandgap semiconductors, SiC and GaN differ in their optimal voltage ranges, switching domains, and cost structures, meaning the answer depends on the application, voltage range, and timeframe under consideration, rather than a simple 'which is superior' approach.

SiC Modules vs. Discrete Components: Selection Criteria

Once the decision to use SiC is made in the early stages of inverter design, the next question is whether to opt for modules or discrete components, a choice that, while appearing to be merely an implementation form, fundamentally impacts system performance, board area, protection circuit design, and procurement flexibility.
