SHOOT THROUGH PROTECTION IN MOTOR DRIVES WITH SINGLE SUPPLY GATE DRIVES
Abstract:
A switch control system includes a first voltage source configured to output a first source voltage on a first voltage line. The system includes a first gate driver, a second gate driver, a third gate driver, and a fourth gate driver. Each of the gate drivers includes shoot through protection (STP) configured to prevent a first switch and a second switch of the system from ever both being closed at once thereby preventing shoot voltages from a DC bus to ground through the first and second switches.
