ACTIVE-POWER FILTER WITH INPUT VOLTAGE FEEDFORWARD AND OUTPUT LOAD FEEDFORWARD

An active-power filter (200) for regulating an input current, comprising: control circuitry (202) to implement the control loops by combining an integrated output voltage (213) with an input voltage signal (211) and an output-load feedforward signal (214), and to generate a control signal (216); and...

Beschreibung
Zusammenfassung:	An active-power filter (200) for regulating an input current, comprising: control circuitry (202) to implement the control loops by combining an integrated output voltage (213) with an input voltage signal (211) and an output-load feedforward signal (214), and to generate a control signal (216); and switching-signal generation circuitry (204) to further implement the control loops by providing a switching signal (220) based on the control signal (216) and a current-sense signal (218), wherein the output voltage (Vo) is loosely regulated by a low-bandwidth control loop and the input current is tightly regulated using current-mode control and a high-bandwith input control loop.
