Abstract


Testing device designed for experimental examination of processes in power electronics devices during various switching modes is described. Through the use of auxiliary circuits additional switching modes (ZVS, ZCS) are realized except hard switching, and turning-off with reduced current respectively. The device’s advantage is possibility of fine dead time setting, allowing us analyzing effects of this phenomenon on measurements of commutation losses. Ill. 12, bibl. 10 (in English; summaries in English, Russian and Lithuanian).
