Infineon proposes a Quasi-Autonomous Gate Driver (QAGD) to manage an electrically actuated component, whether electromechanical, electromagnetic, or electrohydraulic. This paper examines some current control strategies that can be implemented within the QAGD, such as: Synchronous Sampling (SYSA), Hysteresis, Improved Synchronous Sampling-Hysteresis (ISSH), Suboscillation, Suboscillation with Back EMF Feedforward (SBEF) and Synchronous Control in Rotation Coordinates (SCRC). Analysis and simulation of these strategies indicate their advantages and disadvantages, which are then summarized in a comparison chart, from which the best solution for a given application can be determined. The QAGD IC proposed by Infineon adopts this solution by integrating the current controller and the driver unit for the MOSFETs in a single package. The inverter function can therefore be implemented using one QAGD and several MOSFETs, which greatly simplify the system and decrease the costs.
