Abstract
A method for operating a circuit system having at least three control stages for at least three phases, each of the control stages having a high-side switch and a low-side switch, each of the high-side switches and each of the low-side switches being capable of being brought into an electrically conductive state and into an electrically non-conductive state, a quantity being determined that influences the temperature of the high-side switches and/or of the low-side switches, either the high-side switches or the low-side switches being selected in a group as a function of the quantity influencing the temperature, and the selected high-side switches or low-side switches being controlled in a freewheeling phase in such a way that the selected high-side switches or low-side switches form a freewheel during the freewheeling phase.
