Electrical control assembly and electrical device

An electrical device, comprising:

• an electronic control assembly, comprising:
• an electric control board, comprising:
• a first filter circuit comprising at least one distributed capacitance;
• and
• a power supply line for supplying power to an electrical load, comprising a power input terminal, a rectifier circuit, an intelligent power module and a power output terminal, wherein the power input terminal, the rectifier circuit, the intelligent power module and the power output terminal are successively connected, and a first end of the first filter circuit is connected with the power supply line;
• and
• a metal plate arranged on one side of the electric control board in parallel, wherein the metal plate and the electric control board are arranged at intervals, the metal plate is electrically connected with a shell of the electrical load, and a second end of the first filter circuit is electrically connected with the metal plate such that a low impedance loop is formed between the first filter circuit, the metal plate, and the shell of the electrical load, wherein an Electro Magnetic Compatibility (EMC) interference signal generated by a source of the EMC interference signal, after reaching the shell of the electrical load, returns to the source of the ECM interference signal through the low impedance loop and is gradually consumed;
• wherein the first filter circuit comprises a first capacitor, a first end of the first capacitor is the first end of the first filter circuit, and a second end of the first capacitor is connected with the metal plate;
• wherein the first filter circuit further comprises a first resistor and a first inductor, and the first inductor and the first resistor are respectively arranged in series between the second end of the first capacitor and the metal plate.
