Abstract
An electric power conversion device has an electric power converter and a control device. The control device adjusts an output voltage of the electric power converter to approach a first current flowing a first drive switch to an instruction current during a first period in which an input voltage supplied from an AC power source has a positive polarity, and adjusts the output voltage of the electric power converter to approach a second current flowing a second drive switch to the instruction current during a second period in which the input voltage supplied from the AC power source has a negative polarity. The control device operates a switch arranged in a second current sensor during the first period, and operates a switch arranged in a first current sensor during the second period.
