Product Overview

1KW SMPS digitally controlled multiphase interleaved converter using STNRG388A. This evaluation board is intended for evaluating STNRG388A digital controller in offline power conversion applications such as EV battery chargers, UPS and industrial power supplies. The architecture is based on a multiphase interleaved DC/DC converter using half bridge SAB (Single Active Bridge) topology supporting more than 1000W of power. The interleaved topology balances power through 3 parallel stages. Also, the solution delivers high efficiency during the whole load range by enabling one, two or three stages depending on the load. The STNRG388A power conversion dedicated peripherals (SMEDs) offer the flexibility to drive the interleaved power stages while guaranteeing the correct phase realignment during the activation and deactivation of each stage. Due to digital core of the STNRG388A, it is also possible to monitor, control and debug the EVLSTRNG-1KW board via a convenient HyperTerminal control.
  • 3-phase interleaved DC/DC architecture
  • Full load power of 1000W (scalable up to 3KW)
  • Efficiency is more than 94% from 10% to full load
  • Peak efficiency is 96.5% at full load
  • Stand-by consumption is 425mW
  • Input voltage range from 350VDC to 420VDC
  • CC/CV output regulation
  • Output voltage regulation of 133V, output current regulation of 7.5A
  • Maximum output current for each phase is 2.5A
  • Modular power and control board
