description The present invention relates to a high efficiency control technology of a large-capacity DC-DC converter for an electric propulsion vehicle. The present invention is configured to detect information related an output power (a load power supplied by the battery) required from a battery, a battery voltage, and the speed of a drive motor in the electric propulsion vehicle, and configured to control a power conversion equipment by minimally selecting the number of power conversion operation converters to be operated based on the detected information and by determining a variable DC bus voltage value, thereby improving the power conversion efficiency and minimizing an internal resistance loss of the battery and an impact of electromagnetic noise.
