High-power-density modular energy storage converter

A high-power-density modular energy storage converter comprising:

• a cabinet, wherein the cabinet is divided into a first region, a second region and a third region, wherein the first region, the second region and the third region are arranged successively along a first direction, wherein the cabinet comprises:
• a foundation slab, wherein at least a portion of the foundation slab is arranged in the first region, at least a portion of the foundation slab is arranged in the second region, and at least a portion of the foundation slab is arranged in the third region;
• a front structure arranged in the first region, wherein the front structure comprises:
• a power device connected to the foundation slab;
• and
• a first air-water heat exchanger connected to the power device;
• a middle structure arranged in the second region, wherein the middle structure comprises:
• an electric reactor device connected to the side wall of the cabinet, wherein the electric reactor device is connected to the power device;
• a DC magnetic ring device connected to the foundation slab;
• an AC magnetic ring device connected to the foundation slab, wherein the AC magnetic ring device is connected to the electric reactor device;
• and
• an AC filter capacitor connected to the foundation slab, wherein the AC filter capacitor is connected to the AC magnetic ring device, wherein the AC filter capacitor is connected to the electric reactor device;
• and
• a rear structure arranged in the third region, wherein the rear structure comprises:
• a DC contactor connected to the foundation slab, wherein the DC contactor is connected to the power device through a first copper bar, wherein the first copper bar penetrates through the DC magnetic ring device;
• an AC circuit breaker connected to the foundation slab, wherein the AC circuit breaker is connected to the AC magnetic ring device;
• an AC pluggable connector connected to the cabinet, wherein the AC pluggable connector is connected to the AC circuit breaker;
• a DC fast fuse device connected to the DC contactor;
• and
• a DC pluggable connector connected to the cabinet, wherein the DC pluggable connector is connected to the DC fast fuse device.
