  • Intelligent multi-level voltage gate driving system for semiconductor power devices
    Patent number: 11728808
    Abstract: An improved gate driver using a microcontroller (uC), a voltage selector (VS), an adjustable voltage regulator (AVR), and an auxiliary current sinking circuit (ACSC) to actively provide selectable drive signals either higher, lower or equal to the basic on voltage and off voltage drive signals for a selected semiconductor device thereby providing an active voltage-mode gate driver for actively speeding up or slowing both the on time and off time transitions of a semiconductor.
    Type: Grant
