3.6kW 3-level flying cap totem-pole bridgeless PFC reference design
PMP41166
概覽
This reference design is a 3.6kW, single-phase, 3-level flying cap totem-pole bridgeless power factor correction (PFC) converter targeting modular hardware system common redundant power supply (M-CRPS) servers. The PFC operates at continuous conduction mode (CCM) with peak efficiency of 99%. The power stage is followed by a baby boost converter, which helps to greatly reduce the size of the bulk capacitor. This design also includes e-meter functionality with 0.5% accuracy using AMC1306 as a current sensing device, eliminating the need for external power metering ICs. An alternative low- cost current sensing option using TMCS1133 is also provided in this design. The LMG3522 top-side cooled GaN device with integrated driver and protection, enables higher efficiency and reduces power supply size and complexity. The TMDSCNCD28P55X C2000™ real-time microcontroller is used for all the advanced controls including PFC control and e-metering.
特點
- High efficiency (99% peak efficiency) and high power density
- New flying cap voltage method balancing method
- Single current sensor for both PFC control and e-metering with < 0.5% accuracy
- Includes baby boost to extend holdup time and reduce bulk capacitor
- Re-rush current control when AC comes back from dropout
