Description
Bin Wu and four co-authors design a power supply controller for pulsed laser diodes, in a 2025 paper. Switching supplies are compact and efficient, but laser pulses demand a hard trio at once: fast rise, flat current top, and high accuracy. The team interleaves several circuit branches in parallel and mixes control modes.
At light load, a burst-mode voltage control speeds the response and trims extra current. During pulses, a dual-loop current control takes over: an inner loop evens out the branch currents, while an outer loop regulates the total output. Switching between modes follows the control signal's demand for a pulse. Simulations and a built prototype confirmed the scheme. Rise times fell and the output current stayed stable, which is what precision laser driving needs.
