Server battery backup units (BBU)

Infineon offers a wide range of products for battery back-up units in applications like telecom and data centers, both for the BMS and the DC-DC stage

nobutton

Overview

A BMS ensures high performance and safe operation of Li-ion batteries.?It is a must-have and performs actions such as SOC (state of charge) and SOH (state of health) estimations. In battery back-up systems in applications like telecom and datacenters, a BMS circuit is coupled with a DC-DC converter to ensure a regulated output voltage. The DC-DC stage is bidirectional and usually a buck-boost topology, as either single or multiphase.?

Benefits

  • More efficient charge and discharge
  • Efficient DC-DC topologies
  • Accurate battery protection
  • Safe and reliable solution

Infineon: Helping to keep your data center running 24/7

Due to the length and complexity of modern data center tasks, safeguarding uninterrupted operation is a crucial task.

BBUs are critical for providing a reliable source of power in the event of an outage or grid failure, ensuring continuous operation of AI workloads. Infineon's battery backup unit solutions leverage advanced converter architectures to minimize size and maximize output power capability and efficiency. They are based on a partial power concept and can be customized depending on the battery configuration, enabling efficient, reliable, and scalable power conversion and ensuring uninterrupted operation of these critical facilities.

Medium-voltage switches for charge and discharge

The evolution of switched mode power supply (SMPS) topologies enables designers to ensure safe charging and discharging of the equipment¡¯s battery using bi-directional converters through the same terminal. However, to meet the safety requirements and prevent damage and failures, those SMPS need to be equipped with a protection switch. Bidirectional switches are widely used in battery management systems (BMS) to charge/discharge and protect against various failures like in-rush current, overcurrent, short-circuit, reverse voltage, or overvoltage, and undervoltage.

Thanks to our more than 40 years of MOSFET experience and continuous package and technology innovation, Infineon offers decreased?RDS(on) values when moving from OptiMOS? 3 to OptiMOS? 5 in the same package to enable better performance in applications such as BDPS where low RDS(on)?is critical.

Enhancing server battery backup buits with PSOC? Control C3 for superior power efficiency

The PSOC? Control C3P family of MCUs offers significant benefits for server battery backup units (BBUs) by enhancing the performance and efficiency of power conversion systems. The advanced analog features of the PSOC? Control microcontroller, such as its high-performance ADC and high-resolution PWM, enable precise and reliable power management. For instance, the true synchronous "idle" sampling functionality of its single-core ADC can sample up to 16 analog signals with up to 25% faster results, eliminating sampling jitter. This ensures faster and more accurate monitoring of key parameters in battery backup operations.

Additionally, the Timer Counter Pulse Width Modulation (TCPWM) with less than 100 ps resolution facilitates clean and efficient signal generation, allowing in-cycle system control even at high switching frequencies of up to 2 MHz. This level of control is critical for managing the rapid charging and discharging cycles in BBUs while maintaining energy efficiency and stability. By integrating these real-time analog peripherals with the microcontroller, designers can reduce system BOM (Bill of Materials), minimize hardware complexity, and optimize overall costs.

Moreover, the PSOC? Control C3 platform provides the flexibility to incorporate wide-band-gap switches, which are essential for creating next-generation power systems with higher efficiency and durability. These switches enable BBUs to handle higher power densities and thermal loads, making them more reliable and effective in demanding server environments. Overall, PSOC? Control empowers designers to develop innovative, compact, and cost-effective BBUs that meet the evolving needs of modern data centers.

Every switch needs a driver

Every switch needs a driver, and the right driver can make a big a difference. Power electronics applications employ power device switches, and power device switches require optimum gate drive solutions. That¡¯s why we offer more than 500 EiceDRIVER? gate driver IC solutions suitable for any power switch, and any application.

EiceDRIVER? gate drivers provide a wide range of typical output current options, from 0.1 A up to 10 A. Robust gate drive protection features such as fast short-circuit protection (DESAT), active Miller clamp, shoot-through protection, fault, shutdown, and overcurrent protection, make these driver ICs well-suited for both silicon and wide-bandgap power devices, including CoolGaN?, and CoolSiC?. In addition, choose from specifically designed isolated gate driver products for even more protection.
