Abstract:
A driver interface for a switch-based circuit includes an AC coupling capacitor, a first diode or a first series of diodes, and a second diode or a second series of diodes connected in series with the first diode or first series of diodes but with an opposing polarity. The AC coupling capacitor removes a DC voltage from an input bi-level drive signal that does not have the appropriate high and low drive levels needed to switch a FET in the switch-based circuit between fully ON and fully OFF states. The first diode or first series of diodes and the second diode or second series of diodes clamp the resulting AC-coupled drive signal to produce an output bi-level drive signal having the high and low drive levels needed to switch the FET between fully ON and fully OFF states. The driver interface maintains the high and low drive levels of the output bi-level drive signal irrespective of any changes made to the duty cycle or pulse density of the input bi-level drive signal.

Claim (Index 1):
A method of interfacing a gate driver circuit to a switch-based circuit, comprising:\n receiving an input duty cycle varying or pulse width varying bi-level drive signal V drive ; removing a direct current (DC) component from the input duty cycle varying or pulse width varying bi-level drive signal V drive  to produce a level-adjusted duty cycle varying or pulse width varying bi-level drive signal V drive \u2032; clamping the level-adjusted duty cycle varying or pulse width varying bi-level drive signal V drive \u2032 between two levels using a first diode or first series of diodes and a second diode or second series of diodes connected in parallel with the first diode or first series of diodes but with opposing polarity; applying the level-adjusted duty cycle varying or pulse width varying bi-level drive signal V drive \u2032 to a gate of a field-effect transistor (FET) in the switch-based circuit; and switching the FET between ON and OFF states in response to the level-adjusted duty cycle varying or pulse width varying bi-level drive signal V drive \u2032, wherein clamping the level-adjusted duty cycle varying or pulse width varying bi-level drive signal V drive \u2032 between two levels comprises: conducting said first diode or first series of diodes every cycle of the level-adjusted duty cycle varying or pulse width varying bi-level drive signal V drive \u2032 to establish and maintain a high drive voltage level V H  of the level-adjusted duty cycle varying or pulse width varying bi-level drive signal V drive \u2032 within a required acceptable input high-level range of the switch-based circuit over all cycles and irrespective of any changes in the duty cycle of the input duty cycle varying or pulse width varying bi-level drive signal V drive , and conducting said second diode or second series of diodes every cycle of the level-adjusted duty cycle varying or pulse width varying bi-level drive signal V drive \u2032 to establish and maintain a low drive voltage level V L  of the level-adjusted duty cycle varying or pulse width varying bi-level drive signal V drive \u2032 within a required acceptable input low-level range of the switch-based circuit over all cycles and irrespective of any changes in the duty cycle of the input duty cycle varying or pulse width varying bi-level drive signal V drive .
