Abstract: An electric power conversion device comprises switching elements 2a, 2b making up a push-pull converter, a pulse transformer T, a rectification diode D1, a rectification diode D2, a choke coil L, a smoothing capacitor C, a DC magnetic deviation prevention means 3, and an inverter 4. The DC magnetic deviation prevention means 3 detects the coil currents I1, I2 flowing in the primary windings M1, M2 of the pulse transformer T. By controlling (shortening) the on time of the switching element having a greater amount of current, the coil currents I1, I2 are balanced (I1nullI2), thereby preventing the magnetic deviation phenomena of the pulse transformer T.
