Telecom power supply
Increased output power, power density and energy efficiency: this is what’s required today of a telecom power supply. Only Infineon’s efficient, high-quality semiconductor portfolio enables you to achieve it all – and reduce the total cost of ownership (TCO). With our market-leading German-engineered products, reference designs and demo boards, your telecom systems require less cooling and fewer passive components.
What’s more, we provide a full range of semiconductor products – such as our CoolMOS™ and OptiMOS™ MOSFETS and our high-voltage CoolGaN™ solutions – to enable telecom solutions that are robust, high quality and reliable. Your benefits, to name a few: reduced risk of field failures and field returns.
Telecom power supply system diagram
This ZVS phase-shift full-bridge evaluation board represents the newly developed ZVS DC-DC converter for telecom rectifiers with an output voltage from 45 to 56VDC and an output power of 2kW. This converter works with an input voltage between 350 and 420VDC (typical 385VDC) and a switching frequency of 100kHz on the primary side.
The EVAL_800W_ZVS_FB_CFD7 is a high performance example with a complete Infineon solution. The board includes high voltage and low voltage power MOSFETs, controllers and drivers, demonstrating a very effective way to design the high voltage DC-DC stage of a server or industrial SMPS, fulfilling the highest standard of efficiency and reliability.
This evaluation board shows how to design a dual-phase LLC system solution of a server SMPS with the target to meet 80+ Titanium Standard efficiency requirements.
