Patent number: 4816984Abstract: Inverter circuits are provided with bridge arms which, for example, including series-connected transistors (T1l , T2l ) with one freewheeling diode (D1, D2) each transistor. A critical operating state occurs when the recovery current is switched off by one of the diodes (D1, D2), so that the other transistor (T1l , T2l ) is cut in. The return current, which passes through this diode, can assume such high values, when rapidly cutting in the transistor, that the "dynamic" blocking capability of the diode is exceeded, and the diode is burnt out. The load current and the control current are thus reversed, so that the transistor is switched on more slowly and temporarily takes over part of the voltage which is normally applied to the diode.Type: GrantFiled: January 25, 1988Date of Patent: March 28, 1989Assignee: Siemens AktiengesellschaftInventors: Alfred Porst, Gerhard Miller, Mario Feldvoss
