Abstract

48V and 12V power supplies play a critical role in electric vehicle (EV) power systems. In general, 48V transfers energy to 12V to supply lidar, camera, sensors, etc. Once the braking system is activated, the 12V regenerative energy will be returned to 48V for recycling. Thus, a bidirectional conversion of 48V-to-12V is required (top left of Fig. 20.4.1). However, in conventional designs, a bidirectional converter without a seamless control will cause a long current transient duration that results in a large voltage drop on the high voltage (HV) 48V battery system.
