Electrification of Construction Equipment: Application of SiC Inverters in Heavy Machinery
As engineering technology continuously advances and environmental regulations become increasingly stringent, the construction industry is undergoing a revolution— the electrification of heavy machinery. From cranes to excavators, to specialized operation vehicles, these engineering giants are transitioning to hybrid or full electric power, where stability and robust power conversion are fundamental technical necessities. The key to solving these challenges lies not only in advanced power management concepts but also in the support of power conversion devices with exceptional performance.
CISSOID, a pioneering manufacturer of high-temperature semiconductors, is well-known within the industry for its years of deep cultivation in power devices. The company not only provides robust high-temperature solutions but also drives technological innovation at the hardware level. CISSOID, in close collaboration with Silicon Mobility, a leader in power control solutions, has co-developed a fully integrated high-performance SiC inverter reference design aimed at meeting the demanding requirements for high voltage and high power in heavy construction equipment.
This custom-developed 350kW/850V SiC inverter development kit provides robust hardware support to its users, integrating Silicon Mobility's cutting-edge motor control technology to establish an advanced new energy vehicle motor control platform. Its hallmark features are high efficiency, rapid response, and stability in extreme environments, making it highly suitable for the construction equipment application scenario. CISSOID's high-performance inverter is one of the market's leading technological solutions, significantly simplifying the design process and greatly shortening the time from product development to market launch.
Electrification not only makes these machines easier to operate and maintain but also transforms them into drivers of sustainable development through their use of clean energy. Electric cranes provide a quiet and emission-free operating environment, while electric excavators demonstrate unmatched efficiency and flexibility. Specialized operation vehicles are also becoming more environmentally friendly and efficient thanks to electrification.
Furthermore, with the spread of electrification, construction machinery that previously relied on hydraulic or diesel power, such as road maintenance vehicles and bulldozers, is gradually transitioning to electropowered alternatives. These transformations not only reduce fuel costs but also decrease the rate of mechanical failures, improving the reliability and efficiency of operations. The reduction in vibration and noise due to electrification also provides a more comfortable working environment for on-site operators.
The improvement in energy conversion efficiency is another significant advantage brought by electrified construction equipment. SiC inverters play an essential role in this, as they can operate over a broader temperature range while maintaining high efficiency, ensuring the performance of heavy machinery in challenging construction environments. The lightweight design and outstanding energy efficiency of electrified machinery align economic and environmental benefits, propelling the green revolution in the construction industry forward.
The electrification of heavy machinery also leads to new demands on the electrical infrastructure. To adapt to these changes, construction sites need to establish rapid charging stations to ensure the continuous operation of machinery. Electrified construction equipment makes energy supply more centralized and efficient, laying a solid foundation for the construction of smart cities and intelligent construction sites in the future.
In the global trend of green development, CISSOID, as a pioneer in the transformation to electrification, has inverter technology that is an essential cornerstone in building green construction equipment. BONCHIP, as an authorized agent of CISSOID, will realize the widespread application of this technology, providing comprehensive services including supply chain and technical support to users, collectively witnessing and promoting the electrified renovation and sustainable development of the construction machinery industry.
