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 on 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 turn ratio of 10:1 and a 50W Active load. These additional tools are available from our third party tools provider ASCALAB .Active Load can be bought directly from microchip Direct. For isolation transformer you can get in touch with your regional Microchip's sales executive.
The LVPFC Development Board supports:
Single-Phase or Dual-Phase Operation modeDiscontinuous, Transition, Continuous Current mode of operationInput AC Voltage, Output DC voltage: resistive voltage divider senseCurrent Sense in each power switch leg: current transformersZero Cross Detection (ZCD): auxiliary winding placed at storage chokesInrush Current Limiter: Negative Temperature Coefficient (NTC) resistor and relayOutput Overvoltage Protection (OVP): analog comparator with hysteresis, disabling gate drivers. Power reset (unplug the power) is needed to reset that comparatorMating Socket for DP PIM Board
