| Abstract |
The domain of power electronics increases month after month, and today, applications over 50 kVA are found using bipolar Darlington devices. Present packages are, however, thermally limited and paralleling bipolar Darlingtons is the only solution for these applications. This paper gives the designer solution guidelines for paralleling power devices easily and at low cost and give good system reliability as the result. Comparisons will be made of base drive, lay-out, matching device, case temperature effect, overload and current sharing by the hybrid free wheeling diodes. |
