A bidirectional non-isolated hybrid modular DC-DC converter with zero-voltage switching
Elserougi A.; Abdelsalam I.; Massoud A.; Ahmed S. ( Elsevier Ltd , 2019 , Article)In this paper, a bidirectional non-isolated hybrid modular DC-DC converter for high-voltage (HV) applications is investigated. In this configuration, conventional Half-Bridge Sub-Modules (HB-SMs) are employed. The proposed ... -
A Full-Bridge Submodule-Based Modular Unipolar/Bipolar High-Voltage Pulse Generator with Sequential Charging of Capacitors
Elserougi, A.A.; Abdelsalam, I.; Massoud, Ahmed; Ahmed, S. ( Institute of Electrical and Electronics Engineers Inc. , 2017 , Article)Repetitive high pulsed electric field (PEF) is an effective method to kill microorganisms and bacteria in water treatment applications. The PEF can be generated by applying high-power electromagnetic pulse across the sample ... -
