Overview
| Topology | Power Factor Correction |
| Input voltage | 12-26 V |
| Output 1 | 3 V / 5 A |
Description
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.
Features
- Single-Phase or Dual-Phase Operation mode
- Discontinuous, Transition, 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
Typical applications
- Level Translator, Motor and Solenoid Drive
- Line Drivers, Pulse Transformer Drive, Switch Mode Power Supplies
