Modular Multilevel Converter-Based Bipolar High-Voltage Pulse Generator with Sensorless Capacitor Voltage Balancing Technique
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Article)
In order to generate bipolar high-voltage (HV) pulses across certain load from HV dc (HVdc) power supply, a voltage source inverter (VSI) stage should be inserted between the load and the supply. In order to meet the ...
Multi-module high voltage pulse generator based on DC-DC boost converter and CDVMs for drinking water purification
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
High pulsed electric field (PEF) can be used effectively in drinking water purification, by applying it across the water sample to be treated. Application of sufficient high PEF guarantees killing of harmful germs and ...
