Multi-port alternating current and direct current hybrid converter based on multi-winding high-frequency transformer and method

The invention discloses a multi-port alternating current and direct current hybrid converter based on a multi-winding high-frequency transformer and a method. The converter sub-module comprises an active bridge, a resonant branch or a phase-shifting inductor, an n-winding high-frequency transformer and a bridge type interface circuit; the active bridge is connected with a winding of the high-frequency transformer through the resonance branch or the phase-shifting inductor to form a resonance or non-resonance direct-current port, the resonance branch is directly connected with the winding of the high-frequency transformer to form a high-frequency resonance port, and the direct-current port is connected with the bridge type interface circuit to form an alternating-current port; the voltage and the power of each port are controlled through power decoupling in the converter; the converter sub-modules are connected in a tree shape through different ports in a neuron-like mode to form a converter array.
