Résumé

In this article, a source for generating conducted intentional electromagnetic interference with a mesoband spectrum is presented in order to perform electromagnetic susceptibility tests on electronic equipment. This high-voltage source is based on different optoelectronic generators, which integrate photoconductive semiconductor switches (PCSSs) operating in a linear switching mode and triggered by a laser pulse. These optoelectronic devices generate a damped sinusoidal signal with a center frequency between 20 and 200 MHz, a Q factor between 11 and 12.4, and a maximum peak-to-peak magnitude of 3.12 kV for a bias voltage of 4 kV. An optoelectronic generator model was designed using Advance Design System (ADS) software, and experimental tests were performed with a measurement bench to compare simulated and measured results. A study on a voltage increase of these generators has been performed and has established the experimental limits of generation in planar technology with low-cost PCSS available on the shelf. The highest peak-to-peak magnitude value obtained is 6.10 kV, it is possible, thanks to the design and manufacture of a power combiner, with ADS and CST Suite Studio software tools, to set up a multiway combination.
