2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC), 2018
Power electronic transformer (PET) is being widely used in place of line frequency transformer (LFT) in modern power systems. Modular structure, such as cascaded H-bridge (CHB) is preferred solution for PET in high-power and high-voltage applications. For such topologies, the low-frequency ripple powers stored in dc-link capacitors pose passive effects
