Texas Instruments C2000 F28004x | Demoboard PMP41043
1.6-kW reference design with CCM totem pole PFC and current-mode LLC realized by C2000 and GaN
Overview
| Topology | Half-Bridge Converter symmetrical isolated |
| Input voltage | 100-265 V |
| Output 1 | 12 V / 133 A |
| IC revision | E1 |
Description
This reference design demonstrates a hybrid hysteresis control (HHC) method, a current mode control method on half-bridge LLC stage with a C2000 F28004x microcontroller. The hardware is based on TIDA-010062 which is 1-kW, 80 Plus titanium, GaN CCM totem pole bridgeless PFC and half-bridge LLC reference design. A separated sensing card is added for hybrid hysteresis control which recreates the voltage on the resonant capacitor.This HHC LLC stage shows better transient response and ease-of-control loop design compared with the single-loop voltage mode control (VMC) method.
Features
Current-mode controlled LLC10-kHz loop bandwidth< 100-µs recovery time< 500-mV deviation under full load transition
Typical applications
- Server PSU with 12-V output (<= 1 kW)
