Abstract:
The efficient control of a plurality of high side switches, e.g. the high side switches of half bridges is presented. A control circuit contains a charge provisioning unit to provide an electrical charge. The control circuit contains a plurality of sets of high control switches for the plurality of high side switches, respectively; wherein each set of high control switches is used to arrange the charge provisioning unit in parallel to a gate-source capacitance of the respective high side switch. The control circuit comprises a controller to, during a phase of a plurality of different phases, control a respective set of high control switches from the plurality of sets of high control switches to arrange the charge provisioning unit in parallel to the gate-source capacitance of the respective high side switch from the plurality of high side switches, to switch on the respective high side switch.
