Description

technical field [0001] The present disclosure relates to the technical field of power electronic equipment, and in particular, to a power conversion module. Background technique [0002] With the improvement of technologies such as the Internet, cloud computing, electric vehicles and industrial automation, the consumption of electricity is increasing, so the demand for power supply is also increasing, so that the power conversion device must develop in the direction of high power density and high efficiency . In order to meet the power requirements of high efficiency and high power density, the current industry practice is to increase the bus voltage of 12V in the power conversion device to 48V to reduce the current consumption on the bus and the cost of the bus. However, if the bus voltage is to be increased from 12V to 48V, a power conversion module must be added to the power conversion device to convert the 48V input voltage into a 12V output voltage for use by other loa...
