Electroporation is widely used in biological, medical and biotechnological applications, water treatment and food industry. A pulse generator for electroporation in research environment was develop and implemented, its fundamental blocks are a Boost with autotransformer converter and an H bridge with pulse control. The main design calculations and simulations are presented. The results of the built prototype are shown with a pulse amplitude variable between 150V and 1000 V, a pulse width variable between 10 μs and 80 ms and a repetition frequency variable between 1 Hz and 5 kHz.

Practical applications, such as the incorporation of the a new theoretical approach in the definition of the instantaneous and average compensation objectives for active power filters (APFs) in multiphase systems and the description of a global indicator for the evaluation of the power quality are introduced in this paper. In order to obtain these applications, a generalized theory of instantaneous power for nonsinusoidal unbalanced multiphase systems is proposed. The instantaneous power tensor is defined based on the tensor product between vectors of voltage and current. In addition, the simulated results are included.
