A High Power Density Single-Phase PWM Rectifier With Active Ripple Energy Storage (2010, background): “Hence, the need for a better solution to achieve high power density in single-phase rectifiers is apparent, as is the need for an alternative way to filter the low-frequency ripple energy intrinsic to the converter operation [3].”
Single-Phase T-Type Inverter Performance Benchmark Using Si IGBTs, SiC MOSFETs, and GaN HEMTs (2016, background): “where VDC is dc-link voltage, ΔIOUT is output current ripple, fs is switching frequency, and Attreq is required attenuation of the filter [40], [41].”
Decoupling of Fluctuating Power in Single-Phase Systems Through a Symmetrical Half-Bridge Circuit (2015, background): “A well-known problem with such systems is that their AC side instantaneous power contains a fluctuating component that changes at twice the fundamental frequency [6].”
