Einrichtung und Verfahren zum erzwungenen Verteilen der Schaltverluste parallelgeschalteter Transistoren |
摘要 |
<p>A system for sharing of switching losses of parallel transistors is disclosed, said system including a plurality of switching transistors (14,16) connected in parallel for providing a current to a load (22). A pulse generator (31) provides pulse width modulated pulse cycles in response to the load current, each pulse cycle having a pulse signal. An alternate selector (30) is responsive to said pulse cycles, such that for each pulse cycle a predetermined transistor turns ON substantially prior to the other transistors, dissipating substantially all the turn ON losses, and a predetermined transistor turns OFF later that the other transistors, dissipating substantially all the turn OFF losses. <IMAGE></p> |
