METHOD AND DEVICE FOR BALANCING THE POWER LOSS IN SEVERAL CASCODE CIRCUITS CONNECTED IN PARALLEL |
摘要 |
<p>A method and an apparatus for balancing the power loss in at least two electrically parallel-connected cascode circuits, which each have a low-blocking semiconductor switch composed of silicon and a high-blocking-capability semiconductor switch composed of silicon carbide is disclosed. According to the present invention, an output voltage of each low-blocking-capability semiconductor switch is detected, with correction values being established as a function of them, and being superimposed on corresponding control signals for the low-blocking-capability semiconductor switches. An unbalanced current distributor can thus be actively balanced.</p> |
