GATE DRIVER FOR SWITCHING CONVERTER HAVING BODY DIODE POWER LOSS MINIMIZATION
The disclosure relates to a gate driver for switching a converter having body diode power loss minimization. In a switching converter having an inductive load, a current may flow through the body diode of a transistor even though the gate of the transistor is being controlled to keep the transistor...

| description | The disclosure relates to a gate driver for switching a converter having body diode power loss minimization. In a switching converter having an inductive load, a current may flow through the body diode of a transistor even though the gate of the transistor is being controlled to keep the transistor off. Then when the other transistor of the switch leg is turned on, a reverse recovery current flowsin the reverse direction through the body diode. To reduce switching losses associated with such current flows, a gate driver integrated circuit detects when current flow through the body diode risesabove a threshold current. The gate driver integrated circuit then controls the transistor to turn on. Then when the other transistor of the switch leg is made to turn on, the gate driver first turnsthe transistor off. When the gate-to-source voltage of the turning off transistor drops below a threshold voltage, then the gate driver integrated circuit allows and controls the other transistor toturn on.
