摘要：
The present invention relates to a device arranged for converting an AC input voltage to a DC output voltage, comprising a bridgeless boost converter; and a surge protection system. The surge protection system comprises a first protection diode (Dprot1), 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 (Dprot2), 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 (Dprot3), where the anode is connected to a second AC input terminal and the cathode is connected to the positive boost output terminal (Obp); and a fourth protection diode (Dprot4), where the anode is connected to the negative boost output terminal (Obn) and the cathode is connected to the second AC input terminal.
