Design files

Overview

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.

Features
  • 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
