1 Demonstration Application Overview

The dsPIC33C Phase-Shifted Full-Bridge Demonstration Application (PSFB DA) is a development board that supports rapid prototyping and code development based on the Microchip dsPIC33C DSP MCU and the efficient Silicon Carbide (SiC FET) Technology. The design targets 800V to 12V automotive OBC DCDC converter applications but may also be used for any other industrial or telecom application demanding high voltage at the primary and high current on the secondary side.

The board offers well organized circuit blocks, for example: Input EMI filter and protection, SiC primary PSFB, Auxiliary supply, CAN communication and a mating socket for Microchip’s newest Digital Power Plug-In Modules (DP PIMs). The pinout is compatible for CK, CH and the new AK dsPIC^® DSC DP PIMs.
