Input voltage | 120-277 V |
Output 1 | 400 V / 12.5 A |
This reference design is a high-density and high-efficiency 5-kW totem-pole power factor correction (PFC) design. The design uses a two-phase totem-pole PFC operating with variable frequency and zero voltage switching (ZVS). The control uses a new topology and improved triangular current mode (iTCM) to achieve both small size and high efficiency. The design uses a high performance processing core inside a TMS320F280049C microcontroller to maintain efficiency over a wide operating range. The PFC operates with variable frequency between 100 kHz and 800 kHz. A peak system efficiency of 99% was achieved with an open-frame power density of 120 W/in3.
