Abstract :
Comprehensive comparison of continuous and discontinuous Current Source Drivers (CSDs) are presented in terms of switching loss reduction and optimal design for MHz boost PFC converters. The advantages and disadvantages of the continuous and discontinuous CSDs are summarized based on the analysis and experimental results. Both of two drivers are able to achieve the functionality of the PFC boost converters. Overall, the discontinuous CSD achieve high efficiency over the continuous CSD owing to higher gate drive current. A 380V/200W output and 1-MHz boost PFC converter was built to verify the difference between these two types of the CSDs.
