A power supply system for a vehicle is provided. The power supply system includes a high voltage battery pack having a plurality of batteries, a primary isolation converter connected to the high voltage battery pack, and a plurality of distributed isolation converters, each of the plurality of distributed isolation converters connected to one of the plurality of batteries. Each of the distributed isolation converters includes a primary stage configured to receive power from one of the plurality of batteries and an isolation stage configured to provide power to the low voltage bus. A bias signal configured to control operation of each of the plurality of distributed isolation converters is powered by a connected one of the plurality of batteries and is activated based on an enable signal provided by the primary isolation converter.
提供了一种用于车辆的电源系统。电源系统包括具有多个电池的高电压电池组、连接到高电压电池组的初级隔离转换器、以及多个分布式隔离转换器,多个分布式隔离转换器中的每个连接到多个电池中的一个。分布式隔离转换器中的每个包括被配置为从多个电池中的一个电池接收电力的初级级和被配置为向低电压总线提供电力的隔离级。被配置为控制多个分布式隔离转换器中的每个的操作的偏置信号由多个电池中的连接的一个电池供电,并且基于由初级隔离转换器提供的使能信号来激活。
