| Abstract | The fast development and high reliability of quick and powerful bipolar transistors, the development of fast and cheap microcomputers gives the possibility of designing electrical drives with asynchronous motors with a high dynamic quality and a power range of 100 kW. In comparison with DC drives the great advantages of these new drives are: 1. Cheaper and maintenance free motors (no comutator necessary) 2. Higher protection standard - IP 54 and more. During the last few years brushless AC drives more and more claimed modern machine tool applications. This paper proposes a possibility to increase the power of existing drives and to reduce simultaneously noise and current ripple of inverter fed induction machines by a special manner of controlling and splitting the inverter currents. |
