一种具有混合自适应死区控制和峰值延迟控制的高效GaN驱动器

This article presents a GaN driver with a switching frequency (fSW) ranging from 1 to 10 MHz for reliable and efficient power conversion. A hybrid adaptive dead-time control technique is proposed. The dead time is first coarsely adjusted by a digital delay control to achieve a target resolution, and then further fine-tuned by an analog delay control. This approach resolves the inherent trade-off b...
