An electrical energy router includes cascaded submodules. Each submodule of the cascaded submodules includes a rectifying stage and an isolating stage. The rectifying stage includes a structure of a neutral point clamped full bridge. The isolating stage includes a DC-DC converter, which includes a primary side, a secondary side and a transformer. The primary side includes a structure of a neutral point clamped half bridge. A DC side of the neutral point clamped half bridge is connected to a DC bus line of the rectifying stage.
