Texas Instruments UCC28911DR | Demoboard PMP41006
1kW Reference Design Implementing CCM Totem Pole PFC and Current Mode LLC with C2000™ and GaN
Overview
| Topology | Power Factor Correction |
| Input voltage | 100-264 V |
| Output 1 | 12 V / 84 A |
| IC revision | V4.1 |
Description
This reference design demonstrates a hybrid hysteretic control (HHC) method, a current-mode control method, on a half-bridge LLC stage using C2000™ F28004x microcontrollers. The hardware is based on the TIDA-010062 1kW, 80 Plus Titanium Grade, GaN CCM Totem Pole Bridgeless PFC and Half Bridge LLC Reference Design. Hybrid hysteretic control is achieved by additionally adding a proximity card to regenerate the voltage across the resonant capacitor. Compared to the single-loop voltage-mode control method (VMC), this HHC LLC stage has better transient response and easier-to-control loop design.
Features
- Charge or Current Mode Control LLC
- 10kHz loop bandwidth
- Settling time of less than 100µs
- Deviation less than 500mV under full load conversion
- Overcurrent and Overvoltage ProtectionFlexible Synchronous Rectification
Typical applications
- tandalone controller with primary and secondary side control, Server PSU (<= 1kW) with 12V output and digital control
