Adaptive current source driver

 · In this paper, the concept of the adaptive current source drivers (CSDs) is proposed for the high-frequency synchronous buck converters. Compared to the previous CSD circuits, the adaptive CSD can achieve adjustable drive current and drive voltage according to different load condition. The benefit is that higher drive current and voltage lead to lower switching loss and conduction loss when Cited by: An adaptive SiC MOSFET current source gate driver.

WINNER OF YOUNG ENGINEER AWARD An adaptive SiC MOSFET gate driver Author / Editor: Gard Rødal / Johanna Erbacher This article presents a novel current source gate driver for SiC MOSFETs improving controllability of turn-on/off delays, di/dt and dv/dt compared to conventional totem-pole voltage source gate drivers. Digital adaptive Current Source Drivers (CSDs) are proposed for interleaving Boost PFC converters. Adaptive Continuous Current Source Drivers for 1-MHz Boost PFC Converters. Abstract: Recently, current source drivers (CSDs) have been proposed to reduce the switching loss and gate drive loss in megahertz (MHz) dc-dc converters, in which the duty cycle normally has a steady-state value. However, different from dc-dc converters, the duty cycle of the power factor correction (PFC) converters is modulated fast and has a wide operation range during a half-line period in ac-dc applications.
