Abstract A voltage-mode boost converter for automotive (primarily LED headlamp) applications with DSP digital control is presented in this paper. A lean digital control design procedure is proposed. The transfer function of the boost converter's power plant is derived and a three-pole three-zero (3p3z) compensator is designed in MATLAB. The 3p3z-compensator is translated into the z-domain and implemented on a microcontroller with DSP core. A prototype boost converter is designed, built and thoroughly investigated. The performance of the tuned boost controller is evaluated in terms of stability, steady-state precision, transient response and efficiency.
