CPES successfully demonstrated a fully functional integrated 1kW front-end converter for internet servers with more than 75 percent of the energy processing functions integrated into IPEMs. This paves the way for a complete paradigm shift in the electronic control of electrical energy, according to CPES director, Fred Lee.
The system incorporates three major CPES developments, including an active IPEM, a passive IPEM and a filter IPEM. The active IPEM integrates power semiconductor devices and electronic switching components using embedded power technology. The passive IPEM integrates the energy storage inductors, capacitors, and power transformers, and the filter IPEM provides electromagnetic interference attenuation and power frequency propagation.
The successful demonstration is a result of the center’s multidisciplinary team working together to address the intertwined issues of high-frequency power conversion, semiconductor devices, advanced materials, and electro-magneto- thermo-mechanical integration.
