Abstract (en)
[origin: WO2009007175A2] The invention is directed at an electric motor commutator (12) with a switching link (20) with a high-side semiconductor (T1) and a low-side semiconductor (T4). In addition, the commutator (12) has a pulse-width modulator (26) for driving the switching link (20). The pulse-width modulator (26) is connected to both of the semiconductors (T1, T4). The pulse-width modulator is alternately connected through to the two semiconductors (T1, T4). As a result, uniform heating of all of the switching semiconductors (T1, T4) of the switching link (20) is realized, with the result that the power loss and the thermal loading of the switching semiconductors are the same.
