DV330101 Low Voltage PFC Development Kit

Microchip’s DV330101 low voltage power factor correction (LVPFC) development kit offers safe voltage levels at moderate power while designing algorithms on a boost power factor correction topology. These algorithms can be applied to real systems under development with minimal changes. The LVPFC development board utilizes the dsPIC33EP128GS806 device, supporting full digital and advanced power control algorithm schemes. LVPFC development kit utilizes isolation transformer with a turn ratio of 10:1 and a 50 W active load. These additional tools are available from Microchip's third-party tools provider, ASCALAB.

Supports
  • Single-phase or dual-phase operation mode
  • Discontinuous, transition, and continuous current mode of operation
  • Input AC voltage, output DC voltage: resistive voltage divider sense
  • Current sense in each power switch leg: current transformers
  • Zero cross detection (ZCD): auxiliary winding placed at storage chokes
  • Inrush current limiter: negative temperature coefficient (NTC) resistor and relay
  • Output overvoltage protection (OVP): analog comparator with hysteresis, disabling gate drivers
  • Power reset (unplug the power) is needed to reset that comparator
  • Mating socket for DP PIM board
Features
  • EMI/EMC filter at the input (capable of high voltage)
  • Bridge rectifier (3 A max, capable of high voltage)
  • Phase 1 (MOSFET, current transformer, diode rectifier)
  • Phase 2 (MOSFET, current transformer, diode rectifier)
  • Ultra-wide voltage range (UWVR) 5 W flyback (capable of low and high voltage) providing 12 V primary, non-galvanic isolated, and 12 V secondary, 4 kV galvanic isolated voltage

Package Contents

  • Low voltage PFC development board
