This technology relates to multi-level converters. Specifically, it is a multi-level power conversion technology that reduces capacitor ripple using magnetically coupled submodules.
Conventional technologies faced a fundamental problem in modular multi-level converters: as the operating line frequency decreases, the low-frequency ripple component of the submodule (SM) capacitor voltage increases, negatively impacting system performance and lifespan. To address this, the present technology proposes a configuration that includes multiple submodules, transformers, and two consecutive submodules magnetically coupled to the transformer windings and magnetic core, along with two half-bridge switches within each submodule to eliminate ripple power.
As a result, this technology can improve system performance and lifespan by reducing the low-frequency ripple component of the submodule (SM) capacitor voltage, and eliminate the need for large storage capacitors in submodules. It has high utility value in the fields of electricity, power generation, energy, and electronic components.
