CLAIMS 1. Laundry treating machine (100) comprising: - a laundry drum (104) mounted inside said casing (103) to rotate about a rotation axis, - a casing (103), - an electric motor (2) designed to rotate said laundry drum (104) about said rotation axis, - an inverter-based apparatus (l)(la), which is configured to control said electric motor (2) and comprises: - an input stage (4) which is connected to mains lines (8) for receiving AC lines currents and AC mains voltage and configured to convert said alternating mains voltage AC to a rectified DC voltage, - an electrolytic capacitor-less inverter (5) configured to generate output currents to be fed to said electric motor (2) based on duty cycles of switching signals, - a DC-link (10) which connects said electrolytic capacitor-less inverter (5) to said input stage (4) and is crossed by DC-link currents from, or towards, said electrolytic capacitor-less inverter (5), - a DC-link capacitor (11) connected to said DC-link (10), - a regulator system (14)(1 14) which is configured to control the duty cycles of switching signals based on at least a determined/estimated motor value (Id,Iq),(T) indicative of a controlled parameter of said electric motor (2), and at least a motor reference value (Idref,Iqref),(Tref), which is associated to said controlled parameter of said electric motor (2), characterized in that: said inverter-based apparatus (l)(la) further comprises an active voltage limiter unit (15)(1 15), which is configured to regulate said motor reference value (Idref,Iqref),(Tref) in order to limit the DC-link capacitor voltage (Vdc(t)) within a predetermined voltage range.
