| Abstract |
By use of a DC/DC-converter the nearly lossless production of base current is possible. Aspects of implementation of such a converter in the base drive circuit are considered. Effects of base current ripple on different types of power transistors are represented as well as measures for filtering and control strategies. Experimental results show the application on single transistors and darlingtons. Compared with conventional drive circuits the power consumption can be reduced drastically. In the case of darlinoton a profit of maximum current and frequency is reachable. |
