A circuit arrangement (,) for the batteryless power supply of the electronic control of a portable machine driven by an internal combustion engine, which machine possesses a d.c. voltage generator driven by the internal combustion engine, which delivers a generated voltage dependent on the number of revolutions of the internal combustion engine, which is transferred to a rated d.c. voltage (Vcc). The circuit arrangement (,) includes a first rectifier circuit (D,, C,), which converts the generator voltage (Ug) into an intermediate d.c. voltage (Uz), which permits the same, without booster batteries, to reliably and controllably supply the electronics of an engine-driven machine, especially in the starting phase, with the requisite rated d.c. voltage.
