摘要： PROBLEM TO BE SOLVED: To reduce the power consumption of a variable voltage converter by mounting the resistor for detecting current of the variable voltage converter at a position through which current flows intermittently, and providing a digital current detecting part for detecting the current. SOLUTION: The resistor 28 for detecting current of a variable voltage converter 27 is mounted on the downstream side of a switching element 9 through which current flows intermittently, and the current indicated by an arrow 16 of the current flowing through a reactor 8 is supplied to the resistor 28 for detecting current through the switching element 9. The current flowing through the resistor 28 for detecting current is detected by the reference waveform outputting part 32 of a digital current detecting part 29 according to the timing of an outputted signal. As a result, prescribed voltage can be obtained at a position across a smoothing capacitor 11. The current will not flow all the time, thus it is possible to suppress the electric power consumption of the variable voltage converter.

摘要： PROBLEM TO BE SOLVED: To suppress a rush current during recovery and to prevent the occurrence of stress in circuit configuration parts, even though a disturbance has occurred during instantaneous power interruption, by detecting the state of power interruption of input AC voltage, and by transferring a second switching means to non-conduction state by a confirmation signal for power interruption state. SOLUTION: When a power interruption state occurs, power interruption state detection means 24 detects a power interruption state and outputs a power interruption state confirmation signal. If switch transfer means 23 receives this power interruption confirmation signal, then it is processed with priority before a DC voltage confirmation signal output from a DC voltage detection means 22, and a second switching means 10 of a rush current prevention circuit 8 is transferred to non-conductive state. Then, the power supply is recovered and the current flows through an AC power supply 1, rectifying circuit 2, a choke coil, a first switching means 5, a current limiting resistor 9, a rectifying circuit 2 and an AC circuit 1, even when first switching means 5 is in conductive state. Because of this, the rush current is suppressed by the current limiting resistor 9.
