Switching frequency modulation for GaN-based power converters

Abstract: The effects on the EMI spectrum for various switching frequency modulation (SFM) scenarios in a high frequency boost converter are investigated in this paper. A GaNdevice and a Si-device are compared with respect to their EMI behavior, which results from different gate charges and therefore different voltage gradients dv/dt on the power lines. First, the dynamic characteristics of the GaN-HEMT are demonstrated in detail. Then the behavior in the time domain and the frequency domain for switching operations at … Show more

In order to derive ( ), expressions for ( ) and ( ) should be known and equation ( 8) with respect to ( ) then should be solved.…”

“…The Power Converter circuit consumes more power leading to significant power wastage. 100 W power converter with 95% efficiency has a power wastage of 5 W [1][2][3][4][5]. The power wastage largely depends on the power device and its technology used in the converter.…”
