Abstract

The performance analysis of the Fixed Duty Ratio (FDR) and Adaptive Gate Drive (AGD) in high frequency gate driver design is analyzed in this paper. FDR is well known for its simplicity. The limitation of this control scheme requires a longer delay time before the next switching can be executed. As for AGD, the delay adjustment can be controlled for different MOSFET. However, it is hard to detect whether the MOSFET channel is fully turned off before the adaptive delay can be applied. Simulation using the Pspice circuit simulator is carried out to analyze the performances of both control methods on the proposed synchronous buck rectifier converter (SRBC) circuit. The findings show the analysis in converter performance, advantages and limitations of the methods. It is found that even though AGD is known to be better in reducing dead time, using accurate settings of FDR scheme may also introduce significant positive advantage to the converter.
