This invention relates to a modular energy storage converter, belonging to the field of converter design technology. By considering the different heat generation of electrical components in the energy storage converter, this invention divides the electrical components into those with higher heat generation and those with lower heat generation, and sets them in separate zones. The electrical components with higher heat generation are located on the other side of the circuit board and are cooled by a cooling fan, while the electrical components with lower heat generation are located on one side of the circuit board and are cooled naturally without auxiliary cooling devices. This saves on the number of cooling fans, reduces costs, reduces the size of the energy storage converter, and increases power density.
