TIDA-00707 Reference Design

Texas Instruments

1kW: Compact: 97.5% Efficiency: Digital PFC Reference Design for Telecom and Server PSU with E-Meter

Description

TIDA-00707 is a 1-kW: compact (100mmX80mm) power factor converter (PFC) designed for telecom: server: and industrial power supplies. This reference design is a continuous conduction mode boost converter: implemented using a UCD3138A Digital Power Supply controller with all protections built-in. Hardware is designed and tested to pass conducted emissions: surge: and EFT (as per EN55014) requirements.This reference design provides a ready platform of front-end PFC to address various power supplies up to 1 kW:  Improves overall system performance lower bus capacitance: lower RMS currents: and front-end protections. It meets stringent current THD and power factor norms and protects from output overcurrent: overvoltage: and undervoltage conditions.

Features
  • Wide Operating Input Range: 195-V to 270-VACDesigned to Drive Wide Range of Downstream DC/DC Converters and Inverter-Fed Motors up to 1 kWHigh Power Factor > 0.99 and High Efficiency of > 97% at Full Load Over Entire Operating Voltage RangePFC Converter designed with a simple: small PCB form factor (100 x 82mm)
