Voltage Regulation in Buck–Boost Converters Feeding an Unknown Constant Power Load: An Adaptive Passivity-Based Control

Rapid developments in power distribution systems and renewable energy have widened the applications of dc-dc buck-boost converters in dc voltage regulation. Applications include vehicular power systems, renewable energy sources that generate power at a low voltage, and dc microgrids. It is noted that the cascade connection of converters in these applications may cause instability due to the fact that converters acting as loads have a constant...
