Solar PV Inverter maker Sineng design-assisted by onsemi on using SiC and IGBT

Date: 17/05/2023
Sineng electric, China based maker of solar PV inverters is going for long time buy of discrete semiconductor expert onsemi's silicon Carbide MOSFETs and IGBTs to design new solar PV inverters. onsemi not only supplying the switching devices, it is also helping Sineng electric to solve power electronics design problems such as thermal analysis, system level design, and simulations of their inverter products. Both the companies are also in for supply chain understanding for a assured supply of power electronic components during demand spikes, where onsemi and Sineng have extended their existing long-term supply agreement (LTSA), signed in late 2022.

Sineng Electric to use onsemi's EliteSiC silicon carbide (SiC) MOSFETs and IGBT-based high-density power integrated modules (PIMs) in its utility-scale solar inverter and what claimed as industry-first 200kW energy storage system (ESS). Sineng is offering utility-scale solar Photo-Voltaic inverter which is power efficient, simple in design, lower in maintainance costs and lower downtimes compared to a centralized inverter solution finally resulting in lesser cost of ownership.

“onsemi supports us in solving the most challenging technical problems such as system-level design, simulations, thermal analysis and creation of sophisticated control algorithms,” said Qiang Wu, chairman of Sineng Electric. “Integrating the highly efficient EliteSiC technology enables us to develop and implement cutting-edge renewable energy solutions tailored to our customers’ needs. In combination with onsemi’s end-to-end SiC supply chain, we have the supply assurance to plan for long-term growth.”

“Together, we will leverage the benefits of onsemi’s high performance products and Sineng Electric’s expertise in power electronics system design to deliver industry leading solutions for sustainable energy applications,” said Asif Jakwani, senior vice president and general manager, Advanced Power Division, onsemi. “Our continuous pursuit to improve overall system efficiency plays a pivotal role in society moving towards the goal of a net-zero emissions future.”
