摘要
Active power filters and methods control and regulate the input current drawn from an electric power bus to a DC level. Load current fluctuations and ripple current reflected back to the electric power bus are significantly reduced or substantially eliminated. A switch mode power converter with a very low bandwidth output voltage regulation control loop uses input voltage feedforward, output load feedforward, and output voltage feedforward to provide a regulated DC input current significantly attenuating input ripple current drawn from the electric power bus.
