The DV330101 Low Voltage Power Factor Correction (LVPFC) Development Kit from Microchip provides a hands-on platform for evaluating efficient digital power factor correction and advanced power control designs using the dsPIC33EP128GS806 MCU. Built around a conventional interleaved boost PFC topology, the hardware supports 24 VAC input but is designed following high-voltage PCB rules, allowing modification for universal offline voltage ranges of 80–260 VAC with outputs up to 200 W.

The kit enables engineers to safely develop and test PFC algorithms on a boost topology at moderate power levels before applying them to real-world systems. Key hardware blocks include an EMI/EMC input filter, bridge rectifier, dual-phase MOSFET stages with current transformers and diode rectifiers, and an Ultra-Wide Voltage Range (UWVR) 5 W flyback with 12 V primary and secondary rails (4 kV galvanic isolation).

The LVPFC kit also includes an isolation transformer (10:1 turns ratio) and a 50 W active load, available through third-party providers like ASCALAB, supporting comprehensive experimentation and algorithm validation. With full digital control capability, the kit is ideal for prototyping and accelerating development of power electronics applications in low- and medium-voltage systems.
