Description
- SMPS-AC-DC, reference design provides an easy method to evaluate the power and features of SMPS dsPIC Digital Signal Controllers for high wattage AC - DC conversion application. The SMPS AC - DC Reference Design unit works with universal input voltage range and produces multiple DC outputs. The design is based on a modular structure, which features three major power stages, the input stage, intermediate stage and the third stage, a Point of Load. The input stage is a PFC Boost Converter, the intermediate stage is a Phase-Shifted Zero Voltage Transition Converter, which includes ZVT Full Bridge Converter and Synchronous Rectification and the third stage is Single-phase and Multi-phase Buck Converters. This reference design uses two dsPIC33F16GS504 devices, one used for the PFC Boost Converter and ZVT Full Bridge Converter, while the other dsPIC DSC is used for Single-phase and Multi-phase Buck Converters
