Classification: CPC G  H | IPC G  H

Claim 11:
12. An electrical drive circuit for driving an optical load, the electrical drive circuit comprising:
a charging circuit path for charging, during a charging time, one or more inductive elements;
a main circuit path for generating, in a first time interval after the charging time, a main electrical pulse,
wherein a main current provided by the main electrical pulse is direct-current-coupled (DC-coupled) to the optical load; and

a discharging circuit path for generating, during a second time interval, a compensation electrical pulse by discharging the one or more inductive elements,
wherein at least a portion of the second time interval overlaps with the first time interval,
wherein the discharging circuit path includes a first capacitive element in series between the one or more inductive elements and the optical load,
wherein the charging circuit path includes a second capacitive element connected in parallel to a source, and
wherein a compensation current provided by the compensation electrical pulse is alternating-current-coupled (AC-coupled) to the optical load; and

wherein the electrical drive circuit is to:
combine the main electrical pulse and the compensation electrical pulse into a combined electrical pulse, and
provide the combined electrical pulse to the optical load.
