Modified Control for Single-Phase Fuel Cell Systems with Input Ripple Compensation and Improved Output Quality
… the fuel cell source. This low-frequency current ripple has been found to be detrimental to the performance, lifespan, and efficiency of the fuel cell, if not adequately controlled. This thesis presents a current control method for the DC-DC converter stage that reduces the input current ripple …

A Modified Boost Converter with Reduced Input Current Ripple
… with any DC/DC converter. Reducing a converter’s input ripple helps prevent switching noise from spreading to other systems on a shared DC power bus. This thesis covers the analysis, simulation, and implementation of a recently-proposed boost converter topology, alongside an equivalent standard …

Development of advanced power factor correction techniques
… scheme, the PPFC technique allows 68% of input power to go to the output through only one time high frequency power conversion, but still achieves both unity power factor and tight output regulation. A family of PPFC converters were proposed for different power levels, which are simpler …

Advanced Control Schemes for High-Bandwidth Multiphase Voltage Regulators
… control, and avoids the beat-frequency input ripple. A generic small-signal model of the PLL loop is derived to investigate the stability issue caused by the parameter variations. Then, based on the proposed model, a simple adaptive control is developed to allow the BW of the PLL loop to …
