Texas Instruments TMS320F280049C | Demoboard PMP40988 REV E1
Variable-frequency, ZVS, 5-kW, GaN-based, two-phase totem-pole PFC reference design
Overview
| Topology | Power Factor Correction |
| Input voltage | 120-277 V |
| Output 1 | 400 V / 12.5 A |
Description
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.
Features
- 99% efficient
- 120 W/in3 power density
- 5-kW and 20-ms hold up
- 180 W/in3 power density without hold up
- Phase shedding
Typical applications
- EV charging station power module
- Merchant network & server PSU, Merchant telecom rectifiers
- Medium/short range radar
- Solar power optimizer
- DC-input BLDC motor drive, Industrial AC-DC
- Energy storage power conversion system (PCS)
