Systems and methods for reducing low frequency (e.g., 100 Hz, 120 Hz) output ripple of a power converter which receives input power from an AC power source (e.g., AC mains). An output ripple reduction circuit is provided which is electrically coupled between an output of a power converter and a load (e.g., one or more LEDs). The output ripple reduction circuit comprises a transformer having a first winding and a second winding each wrapped around a core. The first winding has a first terminal electrically coupled to an output of the power converter and a second terminal coupled to a capacitor to form a first LC circuit. The second winding has a first terminal electrically coupled to a load and a second terminal coupled to the capacitor to form a second LC circuit.
