Abstract: PURPOSE: A current compensation method of a DC-DC converter for an environment-friendly car is provided to offer an accurate offset value correction by detecting the average value of a pulsating current output as a triangular wave form from an inductor included in a DC-DC converter for an environmentally friendly car. CONSTITUTION: A battery(101) stores DC power supply. A DC-DC converter(102) is installed between the battery and an inverter(103). The DC-DC converter includes a smoothing capacitor(Cbc), an inductor(L), a first switching device(S1) and a second switching device(S2). The DC-DC converter boosts DC voltage supplied from the battery to a preset level and outputs to an inverter(103). A motor(104) generates a driving torque by three phase AC voltage supplied from the inverter. A controller(200) generates a PWM signal for switching the DC-DC converter.
