This paper proposes a step-by-step procedure for designing the LCL filter of a front-end
three-phase active rectifier. The primary goal is to reduce the switching frequency ripple at a …

Grid-connected converters employ LCL-filters, instead of simple inductors, because they
allow lower inductances while reducing cost and size. Active damping, without dissipative …

This paper introduces a new iterative design procedure of L and LCL filters for low-voltage
active-front-end PWM two-level voltage source converters. The analytical expression of the …

voltage-source and current-source topologies for power conversion applications including …

Three-phase active rectifiers guarantee sinusoidal input currents and unity power factor at
the price of a high switching frequency ripple. To adopt an LCL-filter, instead of an L-filter …

Active rectifiers/inverters are becoming used more and more often in regenerative systems
and distributed power systems. Typically, the interface between the grid and rectifier is either …
