Qin Zhen, Vice President of Huawei’s digital energy product line and President of the modular power supply field, pointed out that the new trend of modular power supply will be mainly reflected in the “digitalization”, “miniaturization”, “chip”, “high efficiency of the whole link”, “super fast charging”, “safe and trustworthy” six aspects.
Digitization: "Power components are digitized, visible, manageable, optimized, and predictable in terms of lifespan".
Traditional power components will be gradually digitized, and realize intelligent management at the "component level, device level and network level". For example, server power cloud management, to achieve data visual management, equipment status visual control, energy efficiency AI optimization and other remote intelligent management to improve the reliability of the entire power supply system.
Miniaturization: "Based on high-frequency, magnetic integration, encapsulation, modularization and other technologies to achieve power supply miniaturization".
The sinking of network equipment, power consumption and computing power continues to increase, the high density miniaturization of power supplies has become inevitable. The gradual maturation of high frequency, magnetic integration, packaging, modularization and other technologies will also accelerate the process of power supply miniaturization.
Chip-enabled: "Chip-enabled power supply based on semiconductor packaging technology for high reliability and minimalist applications"
On-board power supply module has gradually evolved from the original PCBA form to the plastic sealing form, in the future, based on semiconductor packaging technology and high-frequency magnetic integration technology, the power supply will be developed from independent hardware to the direction of hardware and software coupling, that is, power supply chip, not only the power density can be increased by about 2.3 times, but also to improve the reliability and environmental adaptability to enable intelligent upgrading of equipment.
All-link high efficiency: "Reshape the power supply architecture, relying on new technologies to realize the overall extreme efficiency."
The full link contains two parts: power generation and power consumption. The efficiency of the components has been continuously improved, and the chip-based on-board power supply is the ultimate in component efficiency. Optimizing the power supply architecture is a new direction to enhance the efficiency of the whole link. For example: digital power supply to achieve a flexible combination of modules, intelligent linkage to match the load demand; server power supply dual-input architecture to replace the traditional single-input power supply mode, not only to enhance the best efficiency of a single module, but also to allow all the power supply modules can be flexibly matched to achieve high-efficiency power supply. In addition, most manufacturers focus only on the efficiency of the primary power supply (AC/DC) and secondary power supply (DC/DC), ignoring the efficiency of the last centimeter of the onboard power supply. Huawei has selected advanced silicon carbide (SiC) and gallium nitride (GaN) materials on the basis of the high efficiency of the first two power supply levels, and based on the digitally modeled design of custom ICs and packages, and the strong coupling of the topology and devices, Huawei has further improved the efficiency of the onboard power supply. efficiency of the on-board power supply to create an extremely efficient full-link power supply solution.
Super fast charging: "Redefining power usage habits, super fast charging everywhere."
Huawei took the lead in proposing the "2+N+X" concept, which integrates wired and wireless fast-charging technologies into N products (such as plugs, wall plugs, desk lamps, coffee machines, treadmills, etc.), and applies them to X scenarios (such as homes, hotels, offices, and cars, etc.), so that users do not need to carry chargers and charging treasures when traveling in the future. Truly realize super fast charging everywhere, creating the ultimate fast charging experience.
Safe and Trustworthy: "Hardware Reliability, Software Security"
In addition to the continuous improvement of hardware reliability, the digitization of power devices, management of the cloud also brings potential cybersecurity threats, and the software security of power supplies has become a new challenge, and system resilience, security, privacy, reliability, and availability have become necessary requirements. Power supply products are generally not the ultimate target of attacks, but attacks on power supply products can enhance the destructiveness of the entire system. Huawei considers user security from the perspective of ensuring that each product is safe and reliable, from hardware to software, so that the customer's product or system can be guaranteed not to be damaged and to be safe and reliable.
Huawei Digital Energy focuses on five major fields: smart PV, data center energy, site energy, vehicle power supply, and modular power supply, and has been deeply engaged in the energy field for many years. In the future, modular power supplies will continue to be rooted in power electronics technology, integrate cross-field technologies, and increase investment in materials, packaging, processes, topology, heat dissipation, and algorithmic coupling to create high-density, high-efficiency, high-reliability, and digitized power supply solutions, so that together with our partners, we can help upgrade the industry and construct the ultimate experience for consumers.
