概要
The STEVAL-DPSTPFC2 kit is a 1 kW power factor correction (PFC) converter based on bridgeless totem-pole topology, operating in continuous conduction mode (CCM) and designed to address high efficiency and power density.
The solution is based on gallium nitride (GaN) technology SGT080R70ILB, and the advantage of negligible reverse recovery losses makes it ideal in this kind of applications where CCM mode is required.
The low frequency leg in this topology is realized using Si MOSFET ST8L65N044M9 instead of using diodes, reducing conduction losses.
The STEVAL-DPSTPFC2 kit regulates a constant output bus voltage both at 115 and 230 Vrms, reaching a peak efficiency of nearly 99%.
The control algorithm is implemented using the vertically pluggable control board, STEVAL-DPS334C1.
The gate drivers used, STGAP2GSN and STGAP2D ensure reliable driving for the GaN and Si MOSFET respectively also providing galvanic isolation.
