Abstract: A current is supplied from a power source voltage supply node of a power source voltage to an open-collector of a transistor through a current blocking circuit, connectors and a signal transmission line. A microcomputer regulates a resistance value of a pull-up resistor by switching over an on/off state of a switch circuit in accordance with the power source voltage detected by a power source voltage detection circuit. The microcomputer thus regulates a current blocking rate of the current blocking circuit.

Abstract: A three-phase regenerative drive (20) is operated based upon power from a single-phase AC source (12) and power from a DC source (14). The single-phase AC input power and the DC input power are converted to DC voltage on a DC bus (24) by a three-phase converter (22). DC power is provided from the DC bus (24) to a three-phase inverter having outputs connected to a motor (34). A controller (44) controls operation of the three-phase converter (22) based upon contribution factors of the AC and DC sources (12, 14) during motoring and regeneration. The controller (44) also controls an AC component of current from the DC source to reduce ripple current on the DC bus (24).

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.
