Abstract
According to one embodiment, disclosed are a DC-DC converter for preventing the unnecessary consumption of a battery in a solar power-linked energy storage system, and a control method thereof. Particularly, a sensing switch is controlled according to a current mode, and thus unnecessary power consumption can be prevented. In addition, a method for operating a circuit breaker, related thereto, is disclosed.
Claims16
A DC-DC converter comprising:
- a converting circuit for converting a power received from the solar power supply;
- a sensing circuit including one or more resistors and a sensing switch, and sensing a state of a battery;
- and
- a processor for controlling the sensing switch based on the state of the battery,
- wherein the processor determines one of a plurality of modes as a current mode based on the state of the battery, and turns off the sensing switch when the current mode is a sleep mode
- wherein the processor determines the current mode as the sleep mode when a remaining amount of the battery is less than or equal to a first value,
- wherein the processor determines the current mode as the shutdown mode when the remaining amount of the battery is less than or equal to a second value, and
- wherein the second value is smaller than the first value.

A DC-DC converter control method comprising:
- sensing a remaining amount of a battery by using a sensing circuit;
- determining one of a plurality of modes as a current mode based on the remaining amount of the battery;
- turning off a sensing switch included in the circuit when the current mode is a sleep mode;
- and
- maintaining the sensing switch in an on state when the current mode is not a sleep mode,
- wherein the current mode is determined as the sleep mode when a remaining amount of the battery is less than or equal to a first value,
- wherein the current mode is determined as the shutdown mode when the remaining amount of the battery is less than or equal to a second value, and
- wherein the second value is smaller than the first value.
