The invention relates to a low-voltage power supply device, a voltage conversion method, equipment and a vehicle, and relates to the technical field of vehicles. The device comprises a power supply module, an inverter, a rectifier, a chopping module and a plurality of load devices, the inverter is configured to convert the first direct current sent by the power supply module into alternating current; the rectifier is configured to convert alternating current into second direct current; the voltage of the second direct current is smaller than that of the first direct current; the chopping module is configured to convert the second direct current into a plurality of target direct currents; the voltages of the multiple target direct currents are smaller than the voltage of the second direct current, and the voltages of every two target direct currents are different. Therefore, the high-voltage direct current can be converted into a plurality of low-voltage direct currents with different voltage grades, and power is supplied to low-voltage electric appliances with different voltage grade requirements in the electric automobile.

    本申请涉及一种低压供电装置、电压转换方法、设备及车辆,涉及车辆技术领域。该装置包括:供电模块、逆变器、整流器、斩波模块和多个负载设备;逆变器被配置为,将供电模块发送的第一直流电转化成交流电;整流器被配置为,将交流电转换为第二直流电;第二直流电的电压小于第一直流电的电压;斩波模块被配置为,将第二直流电转换为多个目标直流电;多个目标直流电的电压均小于第二直流电的电压,且每两个目标直流电之间的电压不同。由此,可以将高压直流电流转换成多个电压等级不同的低压直流电流,为电动汽车中电压等级需求不同的低压用电器供电。
