发明名称 Optimal control of charge-modulated gate drivers
摘要 A system, apparatus and method is arranged to adaptively adjust drive signals for a gate controlled switch circuit such that the amount of gate swing automatically changes based on the load conditions. An adaptive gate charge modulation (GCM) technique can be utilized to dynamically adjust the drive signals so that a substantially constant voltage drop is perceived across to a gate controlled switch circuit. The voltage drop across the gate controlled switch circuit can be set to a reference level that is adjusted whenever a change in system conditions are detected. The gate charge can then be adaptively increased and decreased during operation, within maximum and minimum limits, to substantially match the voltage drop of the gate control switch circuit to the reference level.
