Battery charger/discharger for bipolar microgrids with synchronous bus voltage regulation

HYBRID CONTROL FOR MAXIMUM POWER EXTRACTION AND VOLTAGE STABILITY IN PHOTOVOLTAIC-BATTERY SYSTEMS

Photovoltaic power systems face two main challenges: inefficient power extraction under variations in irradiance and temperature, and DC bus voltage instability due to power mismatches. This paper outlines the development, modeling, and simulation of a standalone PV system with battery storage and DC-DC converters, emp...

DESIGN OF A COMMON GROUNDED HIGH STEP- UP DC -DC COVERTER

This paper presents the design and analysis of a common-grounded high step-up DC–DC converter operating under open-loop control. The proposed converter employs two switches (S1 and S2) with a fixed 50% duty cycle to achieve high voltage gain without the need for extreme duty ratios. The topology maintains a common grou...
