An electronic device, comprising a motor and a motor drive circuit, wherein the motor drive circuit comprises a first operating component and a second operating component, wherein,
- the motor drive circuit further comprises a time delay circuit configured to delay a starting time of the first operating component to be synchronous with that of the second operating component;
- thereby enabling the first operating component and the second operating component to be synchronously started;
- wherein the electronic device further comprises a rectifier, wherein,
- the rectifier comprises a first output terminal and a second output terminal;
- and
- the time delay circuit is connected in series with the first operating component, a series branch of the time delay circuit and the first operating component is connected in parallel with the second operating component across the first output terminal and the second output terminal, and the time delay circuit is configured to adjust a voltage outputted by the first output terminal and provide the adjusted voltage for the first operating component, so that a voltage provided for the first operating component rises to a first preset value that enables starting of the first operating component when a voltage provided for the second operating component by the first output terminal rises to a second preset value that enables starting of the second operating component.
A circuit, comprising a first operating component, a second operating component and a starting time control circuit, wherein,
- a first starting voltage that enables starting of the first operating component is different from a second starting voltage that enables starting of the second operating component, and the starting time control circuit is configured to regulate a starting time of the first operating component to be synchronous with that of the second operating component,
- wherein the starting time control circuit is connected in series with the first operating component, a series branch of the starting time control circuit and the first operating component is connected in parallel with the second operating component across a direct voltage, and the starting time control circuit is configured to adjust the direct voltage and provide the adjusted voltage for the first operating component, so that a voltage provided for the first operating component rises to the first starting voltage when a voltage provided for the second operating component rises to the second starting voltage.
