Abstract
A control method applied to a relay circuit is provided. The relay circuit includes a controller, a relay, a controllable switch, and a power supply. The controllable switch is connected in series with a coil of the relay. The power supply is configured to supply power to the coil of the relay. The controllable switch is controlled by the controller. The method includes: receiving an operating parameter of the relay by the controller; and adjusting a driving force applied to the relay, based on the operating parameter by the controller, to reduce a sum of a conduction loss and a driving loss of the relay, thereby improving the efficiency of the relay.
