3kW PFC (industrial/medical)

98.8% Efficiency at High-Line
No interleaving
90W/in³
Low cost implementation

Features

Description

ICERGi has implemented a 3kW-rated PFC stage, optimized for usage in industrial/medical solutions with higher emphasis on cost. Removing synchronous rectification reduces cost by over a third while sacrificing 0.2% efficiency. A system block diagram shown in Fig. 1 and performance data below.
This unit maximizes the performance of Silicon in AC-DC power conversion, by using ICERGi proprietary gate drivers and control approaches in a 3-level topology with a full-bridge totem-pole implementation using 150V devices.
This unit is based on the scalable and mappable power conversion engine, enabled by ICERGi digital control.
