Powered by ST’s 3rd-generation SiC MOSFET, STGAP galvanic isolation drivers, and STM32 microcontroller technologies, this totem pole power factor correction (PFC) is a turnkey solution that meets the high-end server power design demand for datacenter and telecom power
STMicroelectronics, a global semiconductor leader serving customers across the wide spectrum of electronics applications, has announced a collaboration with Compuware Technology Inc, (Compuware), a leading provider of high-efficiency power supplies, on a reference design for server power using ST’s industry-leading silicon carbide (SiC), galvanic isolation, and microcontroller technologies. This reference design provides unparalleled power-supply options for digital power converter applications including server, datacenter and telecom power.
As demand for digital services continues to grow, fueled by Artificial Intelligence (AI), 5G, and the Internet of Things (IoT), keeping power usage under control is an important piece of the sustainability puzzle for data centers. The STDES-3KWTLCP reference design is perfect for a 3kW and higher wattage CRPS (Common Redundancy Power Supply) server power supply. This technical advancement comes with superior efficiency, faster switching, reduced energy losses, and better thermal management capabilities. In addition, this total system solution shortens time-to-market.
Compuware stands as a global power supply leader, holding the world record for the highest number of 80 PLUS Titanium certifications, ensuring unparalleled power efficiency. Engineered for excellence, Compuware power solutions are the ideal choice for HPC, AI, Deep Learning, Cloud, and advanced applications. With high power density, it optimizes space usage without compromising reliability and efficiency, setting a new performance standard in demanding computing environments.
“Combining ST’s latest SiC MOSFET, galvanic isolation, and microcontroller technologies with Compuware’s leading-edge power energy expertise is helping Compuware unleash our design creativity to develop high-density and -efficiency solutions. Now we can achieve 89W/in.3 power density, a small size, and high power output, this reference design is a great choice for power-hungry, high-performance computing applications,” according to Robin Cheng, Vice President at Compuware.
“With a focus on the Industrial market, ST’s Power & Energy Competence Center provides low-power, mid-power, and high-power solutions with the most advanced ST technologies to our customers, and this reference design- STDES-3KWTLCP can help our customers increase energy efficiency and reduce time-to-market using ST’s efficient and reliable power solutions,” said Eric Chou, Head of Power & Energy Competence Center at STMicroelectronics.
Further Technical Information:
The STDES-3KWTLCP, a 3kW AC-DC converter, is designed for 3kW telecom rectifier applications, which require high efficiency over the entire load range of operation and across the universal mains input voltage range.
This reference design creates a path to a final compact solution up to 40 W/in3 that is greater than existing power supplies while offering high peak efficiency of 96.3%, low THD distortion of less than 5% THD at full load, and a reduced bill of materials.
The full system consists of two power stages. The first is a bridgeless totem-pole PFC controlled by an STM32G474RBT6, and the second is an isolating regulation stage, implemented with a full-bridge LLC network, with zero-voltage-switching (ZVS) PWM and synchronous rectification, controlled by a second STM32G474RBT6 microcontroller.
The STDES-3KWTLCP is a fully assembled kit and helps users to design an innovative topology with the latest ST power kit devices: silicon carbide MOSFETs, high-voltage MDmesh MOSFETs, STripFET MOSFETs, STGAP isolation FET drivers, and a VIPer converter.
