In this paper, a robust digital voltage-mode controller (DVMC) is proposed for a fifth-order boost point-of-load converter. Salient features of the proposed topology are compared with a conventional boost converter. Mathematical models are formulated using a discrete-time modeling technique and then employed in the compensator design, which uses the digital direct design approach. The DVMC is designed...
In this paper a digital PID controller is designed for an H-bridge soft-switching boost converter. The digital PID controller is designed analytically using the discrete-time transfer function of the converter. Using this method, the PID controller gain range is obtained as a set of inequalities in two variables for a fixed third variable. By plotting the region enclosed by the inequalities the controller...
In this paper analysis and robust stabilizing digital controller design for a zero-voltage turn-ON boost converter (ZVTBC) is presented. The steady-state performance and zero-voltage switch-ON methodology has been analyzed and then its state-space models are formulated to obtain the small-signal models. These linearized models are then used in the design of digital voltage-mode controller. A loopgain...
