Interleaved AC/DC Converter Operating with ZVS Sinusoidal Triangular-Current-Mode (S-TCM) for Reduced Voltage Harmonics Generation

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...
