摘要： Control of a converter for an electric vehicle may control the converter of the electric vehicle where the converter is adapted to drop voltage and a counting unit is adapted to count a signal generated by the converter. The control includes inputting a signal generated by the converter to the counting unit during operation of the converter; counting the signal by the counting unit; determining whether a counting result of the counting unit corresponds to a predetermined interval; and deciding that the converter is out-of-order in a case that the counting result does not correspond to the predetermined interval.
