<p>With advancements in industrial technology, the switching power supply has gradually emerged as a preferred choice for laser power supplies due to its advantages of lower power consumption and compact size. However, the simultaneous achievement of short rise time, current flatness, and high accuracy pose significant difficulties for the switching power supply. In this paper, a mixed-mode control of multiple interleaving parallel circuits is proposed. The proposed mixed-mode control incorporates burst-mode voltage control for the light-load state of the laser diode to both fasten the response and eliminate extra current. And a dual-loop current control is employed, where the inner controller averages the branch current and the outer controller regulates the total output current, and hence a balanced current distribution in each branch is achieved to increase the stability of the system. The control mode changing depends on whether the pulse is required to be output in correspondence to the control signal. A simulation model and a multiphase interleaved parallel circuit were constructed to validate the control scheme. Experimental results demonstrate that this algorithm effectively reduces rise time and ensures a stable output current.</p>
