A Smart Controller Based on Cascaded Boost-Buck Converter for High Power Laser Diode
The traditional Buck-Boost topology has large output current ripple, large device stress, and reverse polarity of input and output, so a smart controller based on cascaded Boost-Buck for high power laser diode is proposed in this paper. Firstly, by judging the value of input voltage and choosing different operating modes, the smart controller realizes two switches to be controlled separately, which ensures the stability of output current and increases the flexibility of the algorithm. Then, the effect of the phase shifted Angle on the voltage ripple of Boost output side is analyzed qualitatively. Finally, the simulation model and experimental platform is built to verify the feasibility and effectiveness of the smart controller.
