Abstract
This letter presents a control scheme to operate a boost converter in boundary conduction mode (BCM). In the proposed method, it is assumed that the zero-current information is not available for controlling the converter operation mode. Therefore, a cursor is identified to detect the converter operation mode, i.e., continuous conduction mode/BCM. Details of the cursor and associated control method will be discussed in this letter. We demonstrate experimentally the effectiveness of the proposed method on a GaN boost converter whose active switch current is monitored through a current-mirroring technique.
