A new experimental set-up is developed and validated to characterize high voltage diodes in switch transient regime. Parameters extracted from DMTVCA and OCVD techniques is validated in a buck converter on a resistive load. The experimental set-up enable to measure nice current and voltage transient characteristics, i.e. without noise and high parasitic wiring influence. Experimental results are confronted to device simulations and a good agreement is found.
