Abstract
A converter that may include: a power stage configured to include at least one inductor and a plurality of switching devices, and configured to be able to operate in a buck mode, a boost mode, or a buck-boost mode according to the control; and a controller configured to apply, to the power stage, two or more operation modes selected from the buck mode, the boost mode, or the buck-boost mode, and configured to periodically change the operation mode of the power stage.
Claims10
A converter comprising:
- a power stage configured to include at least one inductor and a plurality of switching devices, and configured to be able to operate in a buck mode, a boost mode, or a buck-boost mode according to the control;
- and
- a controller configured to apply, to the power stage, two or more operation modes selected from the buck mode, the boost mode, or the buck-boost mode, and configured to periodically change the operation mode of the power stage.
A converter comprising:
- a power stage configured to include
- an inductor,
- a first switching device configured to have one side connected to an input voltage and the other side connected to the inductor,
- a second switching device configured to have one side connected to an output voltage and the other side connected to the inductor,
- a third switching device configured to have one side connected to the first switching device and the inductor and the other side connected to a low-voltage line, and
- a fourth switching device configured to have one side connected to the second switching device and the inductor and the other side connected to the low-voltage line;
- and
- a controller configured to control the power stage in two or more operation modes selected from a buck mode, a boost mode, or a buck-boost mode, and configured to periodically change the operation mode of the power stage.
A method for controlling a converter including at least one inductor and a plurality of switching devices, the method comprising:
- a first control step of controlling the converter in one of a buck mode, a boost mode, or a buck-boost mode in a first time period;
- a second control step of controlling the converter in another of the buck mode, the boost mode, or the buck-boost mode in a second time period;
- and
- a repetition step of repeating the first control step and the second control step at a constant period.
