Voltage-mode digital controller for single switch sixth-order boost converter

In this paper a new high gain boost converter is proposed and then a digital voltage-mode controller is designed. Mathematical models are formulated, using state-space technique, and then discrete-time models are established. These discrete-time models are then used in the digital controller design. Salient features of the proposed topology are compared with the conventional boost converter. As the proposed converter is of single switch topology controlling becomes simple even for achieving higher voltage gain with lower duty ratios. To confirm this, design simulations have been carried out on a 30 Watt, 15 -to- 100 V converter system. Experimental results are provided to validate the proposed design.
