Abstract:
1. A ferrite load driver system, comprising: a clock generator operative to generate a digital clock signal; a digital pulse generator operative to generate a first enable pulse having a pulse width substantially equal to a first number of clock pulses of the digital clock signal and a second enable pulse having a pulse width substantially equal to a second number of clock pulses of the digital clock signal; a first driver element operative to receive the first enable pulse and generate in response thereof, a first driver pulse that is operative to drive a current in a first direction through the ferrite load for setting a first magnetic flux; and a second driver element operative to receive the second enable pulse and generate in response thereof, a second driver pulse that is operative to drive a current in a second direction, opposite the first direction, through the ferrite load for setting a second magnetic flux, wherein a leading edge of the second driver pulse substantially coincides with a trailing edge of the first driver pulse.
