Avnet collaborates globally with industry partners to build a green energy storage future
In the face of the daunting challenge of global climate change, we must recognize that alternatives to traditional energy sources are not only an environmental imperative but also a call of our times . Green energy technologies such as wind, solar, and photovoltaic power generation have become key drivers of the global energy transition. With the widespread adoption of these renewable energy sources, the demand for stable and efficient energy storage solutions is increasing. The development of power storage converters ( PCS ), a key technology connecting energy storage systems and the power grid , is crucial for achieving a more efficient, reliable, and intelligent energy system .

PCS: Master of Energy Conversion
The power
conversion system (
PCS
)
is a key component in energy storage systems. The PCS's primary function is to convert electrical energy between the battery energy storage system and the grid. The PCS is capable of bidirectional energy conversion, converting direct current (DC) to alternating current (AC) and vice versa.
Like an electric current conductor, PCS skillfully orchestrates the melody in the symphony of renewable energy sources such as solar and wind power, ensuring grid harmony and efficient energy utilization.
With the rise of renewable energy and the acceleration of grid modernization, PCS technology is also making leaps and bounds to meet the needs of more efficient and reliable energy conversion. The following are several key trends in the development of PCS technology:
High efficiency and low energy consumption
As the bridge between battery energy storage systems and the grid, the performance and efficiency of PCSs have a direct impact on the overall performance of the energy storage system. A high-efficiency PCS can reduce energy loss and improve the performance of the entire energy storage system. To this end, research and development efforts are focused on optimizing circuit design and using more efficient semiconductor materials, such as silicon carbide (SiC) and gallium nitride (GaN). These materials can operate at higher frequencies, providing higher efficiency and lower heat loss.
Intelligent and digital control
Intelligence is another key trend in PCS technology development. By integrating advanced control algorithms and machine learning techniques, PCS can more intelligently respond to grid changes and optimize battery charging and discharging processes, thereby improving overall system performance and lifespan. Furthermore, digital control enables remote monitoring and diagnosis of PCS systems, improving system reliability and maintenance efficiency.
Modularity and flexibility
Modular design is a key approach to improving the flexibility and scalability of PCS systems. A modular PCS allows for easy expansion or contraction based on demand, providing greater design flexibility. This is crucial for responding to changing energy demands and integrating diverse energy systems, such as solar, wind, and the grid.
Win-win energy revolution,
Together we build a new era of green energy
In order to promote the better application of energy storage technology in renewable energy, Avnet, as a leading global technology distributor and solution provider, is working closely with industry partners to promote the sustainable development of new energy and related industries, jointly promote the healthy development of new energy and related industries, and contribute to the realization of a green future.
For example, in the PCS (power storage converter) sector, Avnet has collaborated closely with manufacturers such as Amphenol, Bourns, and Microchip to launch a series of leading technology solutions:
Amphenol Surlok Plus ®
Series Connectors
Efficient and reliable electrical connections are fundamental to energy storage systems. Amphenol Surlok Plus series connectors are ideal for high-voltage, high-current applications. Designed with RADSOK contact technology and high-performance materials, these connectors offer current ratings from 50A to 500A and withstand voltages up to 1,500V DC. Lightweight and space-saving, they feature a quick-lock and keyway design and IP67-rated protection, making them suitable for lithium-ion battery packs, energy storage inverters, and high-voltage control boxes.
The quick-lock and waterproof design of these connectors not only simplifies the installation process, but also improves the durability and environmental adaptability of the entire system. In energy storage systems, which often need to cope with harsh environments and frequent physical operations, the design of such connectors is particularly important.
Bourns BMS Signal Transformers
Bourns BMS signal transformers provide protection and stability in high-voltage battery energy storage systems . These transformers are designed for energy storage systems requiring operating voltages up to 1,500V DC and support the latest solar inverters and power converters. As the voltage level of energy storage systems increases, the isolation requirements and anti-interference capabilities of the components also increase. Bourns BMS transformers ensure reliability and safety in solar and wind energy storage systems connected to the grid by providing an operating voltage of up to 1,500V DC and an isolation voltage of up to 7,640V DC, while operating over a wide temperature range of -40°C to +125°C. Their design also takes into account EMI filtering and isolation requirements, which are critical for maintaining energy storage system stability and improving energy conversion efficiency.
Microchip MCP73223
Battery Charge Management Controller
Battery stability and efficiency are crucial in energy storage systems. Microchip's MCP73223 is an advanced lithium iron phosphate ( LiFePO4 ) battery charge management controller for compact and cost-effective applications. This dual-cell controller offers an unmatched combination of integrated features, including overvoltage protection, a pass transistor, current sensing, and reverse discharge protection. It supports programmable output current from 130 mA to 1100 mA and is fully specified over an ambient temperature range of -40°C to +85°C. Housed in a 3×3 mm, 10-pin DFN package, the MCP73223 is ideal for space-constrained and cost-sensitive applications.
Overall, these products each play a key role in improving the overall performance of energy storage systems, enhancing system safety and reliability , and improving energy efficiency . Through these advanced technological solutions, the energy storage industry can better address growing energy demand and more complex energy management challenges.
Conclusion: Looking ahead, green energy storage technology will continue to be a crucial pillar of the global energy transition. With continued technological advancement and further cost reductions, green energy storage is expected to be applied in even more areas. For Avnet and its industry partners , continued promotion of industry collaboration, innovation, and adoption will not only enable the sharing of resources and knowledge, but also accelerate the global adoption of technology. Through global collaboration, we can hope to see a more prosperous and sustainable world .
