The elevator power supply introduces the mains power into the elevator electrical control system to provide power for the operation of the elevator body. Since the load of the elevator is unbalanced, when the elevator is running in the direction of light load, the elevator is in the state of power generation. For example, when the elevator is running with no load, it goes up to the state of power generation; when the elevator is running at full load, it goes down to the state of power generation.
