1. A power converter for integrated control of electric oil pumps, comprising:
a power conversion module configured to receive direct current (DC) power to convert the DC power into alternating current (AC) power and to output the converted AC power to a drive motor; and
a control unit configured to control the power conversion module and to control actuation of an oil pump for generating hydraulic pressure in a transmission, wherein the control unit comprises:
a control board;
a main controller installed in a partial region of the control board to supply power to the drive motor and to control the power conversion module; and
an oil pump controller installed in a remaining region other than the partial region, connected to the main controller, and configured to supply power to a pump motor for actuating the oil pump and to control the oil pump.
