What makes a power semi unsuitable for use in SSTs?

|
By Jeff Shepard Verified
| EEWorld Online Verified
Engineering is sometimes referred to as the management of technical trade-offs. That can be especially true in complex systems like solid-state transformers (SSTs). A successful SST design balances competing constraints, like extreme heat generation versus a compact solution. That may not always require a wide bandgap (WBG) power device. The use of silicon carbide (SiC) and gallium nitride (GaN) WBG power semis in SSTs drives lots of headlines.

How to read oscillator specs for aerospace and defense designs

|
By Jeff Shepard Verified
| EEWorld Online Verified
Oscillators are critical components in aerospace and defense systems, ranging from communication satellites to portable tactical radios and from ground-based RADAR to the GPS systems in smart ordinance. This article provides a brief overview of several key oscillator specifications, beginning with the basics. Frequency tolerance, also called initial accuracy, is one of the most basic oscillator specifications.

Why is thermal management more challenging for SSTs compared with LFTs?

|
By Jeff Shepard Verified
| Power Electronic Tips
Solid-state transformers (SSTs) offer increased performance but require more complex thermal management compared to conventional line frequency transformers (LFTs). That’s due to the reliance of SSTs on active power electronics and the resulting higher power densities. While LFTs operate at 50 or 60 Hz and use simple cooling designs, SSTs operate at tens of kHz and require advanced systems to dissipate concentrated heat.
