Abstract
A power converter includes an input voltage detection section, a power factor correction (PFC) section, a DC-DC conversion section, and a control section that stops power conversion operation in a case where an input voltage value is greater than or equal to a predetermined value. The control section resumes power conversion operation such that a second input current value lower than a first input current value corresponding to the input voltage value is input into the PFC section after stopping the power conversion operation.
