Wolfspeed powers Telcodium’s lightest 5kW Portable Power Station

SiC is a preferred choice when it comes to high power applications. When Telcodium started desiging their portable power stations, they trusted Wolfspeed for their power electronics requirement. This electric power system,'The Beast' is compact, lightweight and can be used indoor. Read more about Telcodium's journey and how Wolfspeed partnered with them in this process.

Integrated Expertise Delivers the Best GaN Solutions for X-Band PAs

Gallium nitride is the undisputed technology for achieving high-efficiency operation in high-frequency applications, such as those at X-band (8–12 GHz). But device selection for X-band applications doesn’t end with choosing the material technology, because turning the bulk material characteristics into high-performance GaN on SiC devices is quite another matter.

Why Choose SiC over Si for Your Next Bidirectional On-Board Charger Design?

This article discusses the design considerations of on-board charger (OBC) systems and the advantages that SiC has over Si for OBCs, with a focus on bidirectional chargers. The practical advantages of implementing SiC over Si for OBCs are detailed in a comparison of reference designs for a Si and SiC OBC, with a cost savings analysis and breakdown of the system benefits.

GaN Solutions: Small Packages for Big Radar Challenges

AESA systems use active arrays, each with hundreds or even thousands of antennas. In many cases, the system is evaluated on the basis of size, weight, power, and cost (SWaP-C). The technology enabling the latest AESA radar systems must therefore offer significant benefits in terms of SWaP-C improvements.

Application of SiC MOSFETs in 6.6kW High-Frequency High-Power-Density Power Converter

This paper presents the application of Silicon Carbide (SiC) devices in a high-frequency LLC resonant DC/DC converter. With high switching frequencies, the leakage inductance of the LLC transformer can be used as the resonant inductor, resulting in 50% reduction in volume and weight, and 30% decrease in power loss of the magnetic components at 500 kHz and 6.6 kW/400 V output.
