<p>A device arranged for converting an AC input voltage to a DC output voltage comprises a bridgeless boost converter and a protection and stabilisation system. The protection and stabilisation system comprises a first protection diode (D1), where the anode is connected to a first AC input terminal and the cathode is connected to a positive boost output terminal (Obp); a second protection diode (D2), where the anode is connected to a negative boost output terminal (Obn) and the cathode is connected to the first AC input terminal; a third protection diode (D3), where the anode is connected to a second AC input terminal and the cathode is connected to the positive boost output terminal; and a fourth protection diode (D4), where the anode is connected to the negative boost output terminal (Obn) and the cathode is connected to the second AC input terminal. A capacitor (C1-C4) is connected in parallel with each of the protection and stabilization diodes (D1-D4).</p> |
