[0002] Power supply refers to equipment that can provide electricity as a driving energy source. Common power supplies include DC power supply and AC power supply. Power supply is based on the principle of "magnetoelectricity" and is generated by renewable energy sources such as hydropower, wind power, sea tides, water pressure difference in dams, solar energy, and burning coal, oil residue, etc. Electronic equipment refers to electronic products that use power supply as a driving energy source. Common electronic equipment includes computers, servers, communication equipment, mobile terminals, etc.
