750W AC-DC Reference Design

750W AC/DC Reference Design

Overview

Microchip’s 750W AC-DC Reference Design demonstrates a semi-bridgeless PFC topology followed by a peak current controlled zero-voltage switching full-bridge (ZVS FB) converter with digital slope compensation to achieve very high conversion efficiencies. This power supply can be firmware updated (including the compensator algorithm) with zero down time to the system it is powering while the power supply is running. It is implemented using two dsPIC33EP “GS” digital-power DSCs that provide full digital control of the power conversion as well as all system management functions.

The ZVS FB Converter is designed to stepdown an input DC voltage of 400V to an output DC voltage of 12V. A unique feature of the reference design is the implementation of peak current control, using a fully software-based slope compensation algorithm, which eliminates the use of external analog components for slope compensation. The 750W AC/DC Reference Design is royalty free when used in accordance with the licensing agreement.
