Abstract
A power transistor module includes: a power transistor device and a control circuit electrically connected to the power transistor device. The control circuit provides at least one gate voltage to drive the power transistor device, and adjusts the gate voltage in response to at least one signal provided from an external device or fed back from the power transistor device; wherein the gate voltage is greater than a threshold voltage of the power transistor device, and a swing amplitude of the gate voltage is a monotonically increasing or decreasing function of the signal.
