Overview

TopologyLLC Resonant Converter
Input voltage350-400 V
Output 142 V / 9 A
IC revisionC

Description

The design is a 400-W high efficiency battery charger power supply designed to charge wide range of batteries in the voltage range of 20V to 42V and ideal for 10-Cell Li-Ion battery pack used in cordless Power Tools and Garden Tools. The design has boost PFC pre-regulator stage opearting at an efficiency of 96%. It provides high Power Factor(PF) of >0.99 and meets PFC regulation as per IEC61000-3-2 class A. The main converter stage is realised using LLC configuration and operates at an efficiency of 96% at full load. The charger is designed for input voltage range of 175V – 265V AC. The design form factor (230mm x 80mm) is compact for the power level of 400W. The design has an operating overall system efficiency of 92% at full load, with voltage and current regulation within +/- 3%. The EMI filter at the front end of the circuit is designed to meet EN55011 class A conducted emission levels.
