See full text

The invention relates to a circuit unit for driving an electronically commutated fan motor with a power stage for driving windings of the fan motor and with a control stage for driving the power stage. The circuit unit is distinguished in that an operating voltage of the control stage is separated from an operating voltage of the power stage by a diode and in that an arrangement is provided for smoothing the operating voltage of the control stage.
