TLDR
Small signal modeling approach is used to develop an analytical model for average current-mode controlled interleaved boost converter and the experimental results are presented to evaluate the derived model and performance of designed controller.Abstract:
In high power applications, parallel operation of boost converters is recommended. These paralleled boost converters can be operated in interleaved mode. Interleaved mode of operation improves the steady state and dynamic performance of the system. In this work, small signal modeling approach is used to develop an analytical model for average current-mode controlled interleaved boost converter. The controller is designed and implemented for a 500 W interleaved boost converter prototype. The experimental results are presented to evaluate the derived model and performance of designed controller.read more

Design and Analysis of Novel Control Strategy for Battery and Supercapacitor Storage System
TL;DR: In this paper, a simple novel control strategy is designed and analyzed for a hybrid energy storage system (HESS), where batteries are used to balance the slow changing power surges, whereas super-capacitors (SC) are used by diverting the power surges to the SC system.

DC Grid Voltage Regulation Using New HESS Control Strategy
TL;DR: In this article, a new control scheme is proposed to control the power sharing between batteries and supercapacitors to match the generation-demand mismatch and regulate the grid voltage, which not only improves the dc grid voltage regulation capability but also reduces the stress levels on the battery and hence increases the life span of the battery.
