Abstract
The implementation and analysis of a non-isolated DC-DC converter with high gain employing APICs (Active-Passive Inductor Cells) is presented. The func-tion of the converter is established on the parallel charging and series discharg-ing arrangement of inductors. Since the converter is designed using APICs the topology is extendable by increasing APICs. The topology’s key benefit is that it allows for high gain with a much shorter duty cycle and reduced voltage stress on the power devices. The main parameters like voltage gain, voltage stress across all power devices, minimum output voltage ripple and efficicay are calculated. The results are compared in both software and hardware implementations. A 200 W prototype is designed and simulated using Simulink (MATLAB) and a gain of 13 is achieved for an input voltage of 30V. The simulated results are realized with that of experimental results to provide an output voltage of 400 V.
