Infineon Technologies 2EDL8114 | Demoboard DEMO_850W_12VDC_230VAC
Low frequency transformer based SOHO UPS design
Overview
| Topology | Full-Bridge Converter symmetrical isolated |
| Input voltage | 220-240 V |
| Switching frequency | 50-60 kHz |
| Output 1 | 12 V / 75 A |
| IC revision | 1.2 |
Description
The DEMO_850W_12VDC_230VAC is a home and small office UPS solution based on a bidirectional full bridge topology, featuring XMC1300 series microcontroller and 2EDL8114 controller IC. It is intended for use with low frequency iron core transformers. This solution is designed around an XMC1300 series microcontroller with firmware and source code provided. Functionality includes AC power failure detection, alarm, generation of regulated sine wave output voltage and protection against battery faults.This demo board demonstrates a fully functional UPS using SMD MOSFETs and including a heat sinking concept designed around them. It includes a main power board and detachable control card. It is designed for a 12 V nominal DC lead-acid battery. The AC input/output line/load voltage is 220 to 240 VRMS with frequency selectable to 50 or 60 Hz. A soft start function is included to prevent high inrush current. During switch over the drop out time is less than 20ms.Overload and short circuit protection are also included with thermal shutdown if system overheating occurs. Fast and slow battery charging modes are included for lead-acid batteries.
Features
- SMD MOSFET heat sinking concept
- Infineon 2EDL half-bridge gate drivers for high sink/source currents
- Infineon XMC™ microcontroller
Typical applications
- Uninterruptible Power Supply (UPS)
