Abstract
A refrigerator and a method of operating the same are disclosed. In the refrigerator and the method of operating the same, a voltage of an electric power input is measured and rectified through the half wave rectification or the full wave rectification in correspondence with the measured voltage, so that the refrigerator can be used without a voltage converting device when a voltage of the input power is changed. Therefore, the change or the modification of the circuit is not needed in order to use the refrigerator in other regions. Since components are compatible and utility of the components is improved, manufacturing costs can be reduced.
Claims10
A refrigerator comprising:
- a voltage detecting unit for measuring a voltage of an input power;
- a rectifying and smoothing unit for rectifying and smoothing the input power;
- a switch unit connected to the rectifying and smoothing unit and for changing a current flow through the rectifying and smoothing unit;
- and
- a controller for controlling the switch unit in correspondence with a magnitude of the voltage measured by the voltage detecting unit such that the input power is rectified through the full wave rectification or the half wave rectification.
A method of operating a refrigerator comprising a rectifying and smoothing unit for rectifying and smoothing an input power, and inverter, and a compressor, the method comprising:
- measuring a voltage of the input power to compare the measured voltage with a preset reference voltage;
- rectifying the input power through the full wave rectification and smoothing the rectified input power when the voltage of the input power is greater than the reference voltage;
- rectifying the input power through the half wave rectification and smoothing the rectified input power when the voltage of the input power is less than the reference voltage;
- and
- converting the rectified and smoothed input power by the inverter to be supplied as a driving power to the compressor.
