Protection device against the breakdown of bipolar transistors in an integrated driving circuit for power device with resonant load on the collector. |
摘要 |
<p>The protection device (3) comprises automatic commutating means (QP1, QP2; QP3) interposed between the base of the transistor (Q2) to be protected and the collector of the power device (Q3, Q4) to cause a flow of current having a low voltage drop between said base and said collector when the collector voltage (Vc) falls below a predetermined value.</p> |
