Compact High-Voltage AC Generator with Pulse Transformer for High-Frequency Irreversible Electroporation (H-FIRE)
(MDPI, 2021-11-23)
This paper is focused on a design of a high-voltage (HV) generator, which is proposed for a high-frequency irreversible electroporation (H-FIRE). The generator produces bursts of bipolar symmetrical pulses. Most HV sources ...
Identification of Power BJT Operating Stages Based on Experimental Excess Charge Estimation
(IEEE, 2021-05-12)
The paper proposes and demonstrates an experimental waz of estimating the amount of stored charge of excess minority carriers within power BJT base and collector. This consequently allows a detailed identification of ...
