Abstract
A free-running circuit arrangement for operating a load, has at least one switching element, a freewheeling diode connected in an anti-parallel fashion relative to the main current direction of the at least one switching element, a load circuit and a control resonant circuit which comprises at least one control inductor and at least one self-capacitance of the at least one switching element. The at least one switching element has a control electrode, a working electrode and a reference electrode, a capacitance acting between the control and working electrodes that is coupled to the control resonant circuit such that energy is fed into the control resonant circuit by the charging and discharging current of this capacitance, the circuit arrangement having no components for feeding energy into the control resonant circuit by electromagnetic coupling.
