PMP10110
具有 PFC 的通用 AC 輸入轉 30Vmax@6A 鉛酸電池充電器參考設計
PMP10110
概覽
The PMP10110 design converts the universal input AC voltage to isolated 17V...30V@6A and is suitable to charge lead-acid or Li-Ion batteries. The converter is a constant-V and constant-I genarator and the set points for output voltage (charge level) and current are settable by means of two PWM signals. The first stage is a PFC boost while the isolation ad current stabilization is performed by DC-DC half bridge stage. An isolated quasi-resonant flyback converter supplies all internal voltages and provide some extra current for external loads (fan or analog section), in details 12V@400mA and 5V@300mA.
特點
- The first stage is a CCM PFC boost driven with UCC28180, showing high efficiency and low EMI signature
- The second stage is a DC/DC half bridge, wich includes both current and voltage loops; a PWM signal is used as reference for voltage and current
- An auxiliary power supply generates all needed voltages; a network is disconnecting all resistors tied to high voltage to reduce stand-by losses
- Plug-to-plug efficiency at full load: 86%...92% in the whole input voltage range
- This design is tested and includes test results and CAD files
