摘 要：
Power converter, comprising: a rectifier (22) configured to rectify an input alternating current (AC) from an AC power source (91); a power factor corrector (25) configured to perform a power factor correction operation on an input voltage (V1) emitted from the rectifier (22); a power converter (28) connected to an output of the power factor corrector (25) and configured to generate output AC power (SU, SV, SW); and a controller (31g) configured to control the power factor correction
operation by means of the power factor corrector (25), characterized in that the controller (31g) is configured to (i) turn on the power factor corrector (25 ) and make the power factor corrector (25) perform the power factor correction operation if a parameter value, which is calculated by

摘 要 附 图：
the controller (31g) from an input current (Im) flowing at the power factor corrector (25), or that is a value for the input power at or the output power from the power factor corrector (25), is greater than or equal to a first threshold, and (ii) turn off the power factor corrector (25) and make the power factor corrector (25) stop the power factor correction operation if the parameter value is smaller than or equal to a second threshold below the first threshold; and over a predetermined period of time (Tg) from a moment when the power factor corrector (25) is switched either from on to off or from off to on, the controller (31g) is configured to maintain a state of the switched power factor
corrector (25) regardless of the parameter value. 主权项： 5/n
