Method for reducing losses during the commutation process |
摘要 |
The invention provides a method by which losses are reduced during the commutation of a free-running, driven power converter valve (T2) of an invertor phase (2) to a current-accepting power converter valve (T1) of said invertor phase (2). The current-accepting power converter valve (T1) is switched on at the beginning of the commutation process and the free-running, driven power converter valve (T2) is rapidly switched off as soon as the value of its drain voltage (UD) is zero.
