Webinar: Benefits & Advantages of GaN in a Data Center PSU

In This Webinar You’ll Learn:

  • The Economic and Sustainability value of GaN in Power Supply Units
  • GaN’s technical advantages in Power Factor Correction and LLC Resonant Converter topologies
  • How to take advantage of GaN Systems’ Next Generation Power Stages in 3 key areas:
    • Thermal Performance
    • Switching Performance
    • Efficiency Improvement

Questions & Answers

GaN not only provides a much lower switching loss but also enables the use of the totem pole PFC topology, which has better magnetic and semiconductor utilization. GaN provides a significant advantage for increasing the power density of the power converter along with increasing efficiency.

Interleaving is a great way to reach higher power and higher power density for power converters. The interleaved two-phase topology can cancel each other’s noise and current ripple to reduce the EMI filter and magnetics components size. However, there is a bit of a cost premium for interleaving drivers, aux power supplies, and a more powerful controller. So, there is a trade-off, and the decision is case by case depending on design objectives.

Although CRM control can achieve ZVS to reduce switching loss and hard switching noise, when the power is higher than 1kW, the peak current for CRM will be somewhat challenging to handle. So, in general, CCM is more recommended.

Yes, visit our website for our 3kW PFC and LLC reference designs. The IMS boards are also available on our website. You can review details on the “Evaluation Kits & Reference Designs” section in “Design Center” pulldown area of our website. You can purchase them from our distributors.

GaN has a faster switching transition than SiC. For data center applications, 650V GaN solutions have higher efficiency and power density compared to Silicon Carbide.
