20140043076 | Pulsed Gate Driver - A gate driver includes a control input receiving a control signal, an output to provide an amplified output signal to the gate, and controller. The controller produces an adaptive pulse train varying with the control signal. An adaptive incrementer produces a sequence of numbers that set a slew rate of the switch, and a look-up table is fed with the sequence of numbers, and associates the numbers produced by the adaptive incrementer with values representing the duty cycle of the output signal to control the slew rate of the switch. The switch can be driven at various intermediate levels, and allows gate drive conditions to adapted to abnormal system states by varying the control input signal. The adaptive response allows the slew rate to vary without replacing any gate driver circuit components. Because the gate current is provided adaptively, the delivery of gate current results in low power dissipation. | 02-13-2014 |
