Optically activated semiconductor devices play a very attractive role in power circuits control applications. In fact, due to the very high galvanic isolation between the control circuit side and the power circuit side, these specific devices can solve the safety problems and eliminate the unintentional switching. In an earlier work [5], a detailed theoretical and numerical analysis of the BMFET as an optically controlled switch is presented. In this paper,,ve complete the previous analysis by presenting experimental results on the optical switching of various kinds of bipolar mode field effect transistor (BMFET) obtained with a low-power optical source. The BMFET's used are different in design parameters and geometries. The results obtained are in good agreement with our previous theoretical and numerical previsions.

Abstract
Optically activated semiconductor devices play a very attractive role in power circuits control applications. In fact, due to the very high galvanic isolation between the control circuit side and the power circuit side, these specific devices can solve the safety problems and eliminate the unintentional switching. In an earlier work [5], a detailed theoretical and numerical analysis of the BMFET as an optically controlled switch is presented. In this paper,,ve complete the previous analysis by presenting experimental results on the optical switching of various kinds of bipolar mode field effect transistor (BMFET) obtained with a low-power optical source. The BMFET's used are different in design parameters and geometries. The results obtained are in good agreement with our previous theoretical and numerical previsions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
