According to the characteristics of dual buck full-bridge inverter, an improved model predictive current control (MPCC) strategy is used. Compared with the traditional model predictive current control scheme, the new model predictive current control can reasonably allocate times of different switching state through the principle of the minimum current error in a single sampling period, which can reduce the inductor current ripple caused by dual buck full-bridge inverter and improve output waveform quality of the dual buck full-bridge inverter. Simulation and experimental results verify the feasibility and correctness of this scheme.

The high-power laser diode driver (HPLDD) that combines the buck-boost converter (BBC) and feedback controllers was designed and implemented for the vehicle headlights. The buck-boost converter could be operated in all conversion modes including step-up, step-down, and step-up-down, with variable battery voltages input to the HPLDD. Moreover, the feedback controllers composed of a voltage-loop controller (VLC) and a current-loop controller (CLC) to control the BBC's output voltage and current to drive high-power laser diodes (HPLDs). In the start-up phase, when the BBC output side is operated from the constant-voltage mode and changed to the constant-current mode, a current overshoot occurs, which can damage the high-power laser diodes. This paper proposed a control method, the proportional-switching-proportional-integral control technology, can be used to the CLC to reduce the start-up current overshoot.
