Abstract
A low voltage DC/DC converter (LDC) control apparatus for controlling an LDC including a transformer and a PWM controller is provided. The low voltage DC/DC converter (LDC) control apparatus includes an input current calculating unit calculating an input current of the LDC by using magnetization inductance information on the transformer and effective duty information on the PWM controller; an output current calculating unit calculating the instantaneous value and average value of an output current based on the input current calculated by the input current calculating unit; and an LDC control unit generating a control signal for over current protection (OCP) or power limit based on the instantaneous value and average value of the output current calculated by the output current calculating unit, wherein the LDC control unit outputs the generated control signal to the PWM controller.
