Abstract: A motor control device of an air conditioner may include: a DC/DC converter that level-changes a DC power supply supplied from the outside to output the level-charged DC power supply to a DC bus terminal; a bidirectional DC/AC converter that converts the DC power supply of the DC bus terminal into an AC power supply to transfer the converted AC power supply to a system, or that converts the AC power supply from the system into the DC/power supply to supply the converted DC power supply to the DC bus terminal; and an inverter that converts the DC power supply of the DC bus terminal into the AC power supply by a switching operation, and drives a compression motor by the converted AC power supply.

Abstract: Provided are a cooker and a method of controlling the cooker. An image of food scanned by an image sensor is corrected, and thus, can be free from distortion due to a lighting device. Accordingly, a user can more accurately recognize a cooking state of the food.

Abstract: Provided are a cooker and a method of controlling the cooker. An image of food scanned by an image sensor is corrected, and thus, can be free from distortion due to vapor generated while cooking the food in a cooking chamber. Accordingly, a user can more accurately recognize a cooking state of the food.

Abstract: The present invention relates to a motor control device of an air conditioner using a distributed power supply, comprising: a DC/DC converter which level-converts a DC power supply supplied from the outside to output the level-converted DC power supply to a DC bus terminal; a bidirectional DC/AC converter which converts the DC power supply of the DC bus terminal into an AC power supply to transfer the converted AC power supply to a system, or which converts the AC power supply from the system into the DC/power supply to supply the converted DC power supply to the DC bus terminal; and an inverter which converts the DC power supply of the DC bus terminal into the AC power supply by a switching operation, and drives a compression motor by the converted AC power supply.

Abstract: Provided are a cooker and a method for controlling the same. A cooked degree of food may be determined through a variation of a food size read from a food image scanned by an image sensor in a cooking chamber. Thus, the cooked degree of the food in the cooking chamber may be more accurately determined.

Abstract: Provided is a cooker. An image of the inside of a cooking chamber scanned by an image sensor is displayed to the outside through a display part. Thus, a user may more easily and accurately recognize the inner state of the cooking chamber.
