  • Circuit arrangement
    Patent number: 8890466
    Abstract: A circuit arrangement, especially for supplying an electromagnetic holding brake with a clocked supply voltage, includes a module for controlled provision of a clocked supply voltage for free-wheeling operation of the holding brake. The module has a switching unit for switching off the supply voltage for braking operation. A free-wheeling diode and a suppressor diode are connected in parallel to an inductance of the holding brake, with the free-wheeling diode being effective in free-wheeling operation only and the suppressor diode being effective in braking operation only.
    Type: Grant
