A power supply system according to the present invention comprises: a low voltage DC/DC converter (LDC) that converts supplied high voltage to low voltage; a main battery that is charged through the LDC and supplies power to a junction block separated into an essential load and a general load through the LDC; a first power switch that controls power supply between the LDC and the junction block; a second power switch that controls power supply between the main battery and the junction block; a control block having a load switch that selectively blocks the power supply to the general load; and an auxiliary battery that selectively supplies power to an auxiliary junction block separated from the junction block.

    본 발명은 공급되는 고전압을 저전압으로 변환하는 LDC(Low Voltage DC/DC Converter), 상기 LDC를 통해 충전이 이루어지며, 필수 부하 및 일반 부하로 분리된 정션 블록으로 전원을 공급하는 메인 배터리, 상기 LDC 및 상기 정션 블록의 상호 간의 전원 공급을 단속하는 제1전원 스위치와, 상기 메인 배터리와 상기 정션 블록의 상호 간의 전원 공급을 단속하는 제2전원 스위치 및 상기 일반 부하로의 전원 공급을 선택적으로 차단하는 부하 스위치를 구비하는 제어 블록 및 상기 정션 블록과 분리된 보조 정션 블록으로 선택적으로 전원을 공급하는 보조 배터리를 포함한다.
