摘要： PROBLEM TO BE SOLVED: To provide an inverter and a refrigerator capable of suppressing rising of temperature of a power semiconductor. SOLUTION: A plurality of power semiconductors 38 form an inverter circuit 33, and a micro computer 37 controls switching of the power semiconductors 38. The micro computers 37 sets any one of power semiconductors 38 to be on-operation for a set time T just before a motor 11 is driven, and makes a DC current flow the motor 11 so that the rotor of the motor 11 is aligned with an initial position. The power semiconductors 38 are rotated to be set on-operation each time the control is performed. So, even if start/stop of the motor 11 is frequently performed, the energizing is distributed among the power semiconductors 38 to avoid concentration of heat. The temperature of any one of the power semiconductor 38 is suppressed from rising excessively. COPYRIGHT: (C)2004,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To delicately control even when a load is largely changed by more enlarging cooling capacity by PWM controlling a switch element by a pulse width modulation based on a value detected by a DC voltage detecting means. SOLUTION: This air conditioner comprises a switch element 3 disposed in parallel with a DC power source rectified by a rectifying diode module connected to an AC power source, a DC voltage detecting means 10 for detecting a DC voltage of the DC power source, and a PWM control means 11 for controlling the element 3 by a pulse width modulation. The element 3 controls current of an AC reactor 17 to step up a DC voltage Vdc, and is PWM controlled by a PWM control means 11. The means 11 is controlled in response to change of the voltage Vdc of an input parameter detected by the means 10. Thus, DC voltage input to an inverter is always maintained constant. Accordingly, cooling capacity of the air conditioner can be enlarged.
