一种具有减少组件和简化控制的级联H桥变换器集中式有功功率解耦方法

Cascaded H-bridge converters (CHBCs) are widely utilized in medium- and high-voltage systems. However, they present challenges such as large submodule (SM) capacitance and complex capacitor voltage balancing strategy. To improve converter power density and reduce hardware consumption, this letter proposes a new topology for CHBC, which features centralized active power decoupling (APD) capability....
