"Pulsed Power is an emerging and multidisciplinary research field"
Bioelectrics and Industrial applications
The effect of intense pulsed electric fields on biological cells has been the topic of research since the late 1950s. It has been shown that cells have a capacitive-resistive model and if too much charge gathers at the cell membrane, the electric field breaks the membrane down, creating pores. A series of short, high voltage pulses can expand the pores in the cell membrane until the cell wall breaks down, killing the cell. This process can be applied to contaminated water to kill bacteria. Studies have indicated that the most important factor in the success of pulsed power water decontamination is the rise time of the pulse, which needs to be as low as nanoseconds. Hence new pulsed power converters are needed for this application to reach its full potential as a safe efficient water decontamination treatment.
Pulsed Power: topology and applications
When an electrical energy is stored in a system over a long time and is released over a short time, a huge amount of peak power can be delivered to a load. This is known as pulsed power, a powerful pulse with a short pulse width. There are two different types of energies which can create pulsed power such as a) switching of voltage (electric field) stored in a capacitor and b) switching of current (magnetic field) stored in an inductor. In this project, our main focus is pulsed voltage.
