Abstract
One aspect of the present disclosure relates to a system that can remove contaminating noise (e.g., direct current (DC) contamination or high frequency contamination) from an electric waveform. The system can include a passive filter that includes at least a secondary-side-open-transformer-inductor (SOTI). The SOTI can include a first coil inductively coupled to a second coil. The first coil of the SOTI can receive the electric waveform contaminated with the noise and output the electric waveform. The second coil of the SOTI can provide an impedance that facilitates removal of the noise from the electric waveform.
