“…According to the component characteristics in the third stage, many alternative solutions have been proposed to avoid the use of a bulky and low-reliability device [13][14][15][16][17]. Some of these solutions have been classified into two principal groups [18][19][20][21][22][23][24][25][26]: passive and active power-decoupling methods (PPD and APD, respectively).…”

This study compares ripple port, stacked switched capacitor, and capacitive energy storage architectures for active power decoupling, comparing the number of components, performance, energy density, DC-link capacitor reduction, efficiency, and frequency operation to highlight their main benefits and drawbacks for single-phase grid-connected applications. The overview reveals equivalent effective energy density without electrolytic capacitors, as well as enhanced simplicity, performance, and durability, thereby providing stacked switched capacitors as an attractive power-decoupling alternative for multi-stage connected applications, based on the principle that its individual buffer capacitors absorb and deliver energy without tightly constraining their individual terminal voltages, while maintaining a narrow range voltage at the buffer DC port.
