A Demand Side Management Controller Configuration for Interleaved DC-DC Converters Applicable for Renewable Energy Sources
Ertekin, Davut; Bayrak, Gökay; Subramaniam, Umashankar (Wiley, 2021)In Micro-grid applications, accuracy and sensitivity of the Demand Side Management (DSM) process decrease when the load impedance changes. In this study, the impact of the DSM is analyzed and the interleaved structure is ... -
Influence of a Proposed Switching Method on Reliability and Total Harmonic Distortion of the Quasi Z-Source Inverters
Hang, Liu; Subramaniam, Umashankar; Bayrak, Gökay; Moayedi, Hossein; Ghaderi, Davood; Minaz, Mehmet Recep (Ieee-Inst Electrical Electronics Engineers Inc, 2020)An Improved Sinusoidal Pulse Width Modulation (ISPWM) technique carried out to obtain pure sine waves for voltage and current signals in Quasi Z-Sourc Inverters (QZSIs) in the load side is given in this study. This switching ... -
Investigation of the Thermal Loading and Random Vibration Influences on Fatigue Life of the Solder Joints for a Metal-Oxide-Semiconductor-Field-Effect Transistor in a DC-DC Power Boost Converter
Li, Songgang; Subramaniam, Umashankar; Yang, Guobiao; Ghaderi, Davood; Rajabiyoun, Niloufar (Ieee-Inst Electrical Electronics Engineers Inc, 2020)This study presents the effects of the vibration and thermal cycling on the fatigue life of a power Metal Oxide Semiconductor Field Effect Transistor (MOSFET) in a power converter circuit. The fatigue mechanism in per ... -
Leakage current repression and real-time spectrum analysis with chirp Z-transform for a novel high-efficiency PV-based inverter applicable in micro-grids
Bayrak, Gökay; Ghaderi, Davood; Subramaniam, Umashankar (Springer, 2020)One of the most critical elements in the connection of photovoltaic (PV)-based systems used to generate electricity from solar energy is the inverter. The harmonic effects of the inverters to be connected to the grid should ...
