A low voltage DC-DC converter of an eco-friendly vehicle includes: a first DC-DC converter configured to reduce a second voltage lower than a first voltage supplied to a driving motor of the vehicle to a third voltage; a voltage regulator configured to regulate the third voltage to output a fourth voltage lower than the third voltage; a controller configured to operate in response to the fourth voltage; and a second DC-DC converter configured to convert and output the first voltage to a third voltage in response to an output signal of the controller, in which an output voltage of the second DC-DC converter is supplied to the voltage regulator.

    本发明提供一种环保车辆的低压DC‑DC转换器及输出恒定电压的方法,该低压DC‑DC转换器包括:第一DC‑DC转换器,配置为将比供应给车辆的驱动电机的第一电压更低的第二电压降低到第三电压;电压调节器,配置为调节第三电压以输出低于第三电压的第四电压;控制器,配置为响应于第四电压进行操作;以及第二DC‑DC转换器,配置为响应于控制器的输出信号将第一电压转换并输出为第三电压,其中,第二DC‑DC转换器的输出电压被供应给电压调节器。
