Abstract

The sinusoidal Triangular-Current-Mode (S-TCM) method has been proposed in the AC/DC power-factor-correction (PFC) converter to achieve the zero-voltage-switching (ZVS) which can lead to both, high efficiency operation and a high power density design. Nevertheless, the necessary wide range variation of the sinusoidal switching frequency profile imposed by the S-TCM results in a larger generated voltage harmonic peak due to the overlapping between different order carrier-frequency harmonics. In this work, the S-TCM is used in the interleaved 2-level converter to minimize the undesirable effects of such overlapped voltage harmonics while maintaining ZVS via S-TCM. Meanwhile, the necessity of coupled inductors (CIs) in the interleaved topology is avoided by implementing the S-TCM. Both simulation and experimental tests conducted in a 3.3 kW interleaved 2-level converter system are used to verify the study.
