Single-Phase Three-Level Flying-Capacitor Buck PFC Rectifier
₹4,500High-Power-Density Single-Phase Three-Level Flying-Capacitor Buck PFC Rectifier Abstract-Active pulsating-power-buffering (PPB) is an effective technique to reduce the energy storage requirement of a singlephase power-factor-correction (PFC) rectifier. Existing singlephase solutions with active PPB, however, generally suffer from high voltage stresses, leading to increased power losses as well as the need for high-voltage-rating semiconductor switches.
