New Electronics – onsemi strives to simplify the design of renewable energy applications

According to onsemi, these modules offer higher power density and provide up to 10% more power output than many other competing products.

Powered by the latest IGBT Field Stop 7 (FS7) technology, the 800 A(A) QDual3 module delivers increased levels of performance to reduce system costs and simplify designs. In a 150 kW inverter, the QDual3 module will dissipate 200 W less compared to the nearest competitor, significantly reducing the size of the heat sink.

QDual3 is designed to operate in harsh environments and is intended for high-power electronics converters such as central inverters in solar farms, energy storage systems (ESS), commercial agricultural vehicles (CAV) and industrial motor drives.

Currently, two products are available depending on the application – NXH800H120L7QDSG and SNXH800H120L7QDSG.

At a time of increasing use of renewable energy, which has increased the need for solutions to manage peak demand and ensure continuity of energy supply, “peak shaving”, the practice of reducing electricity consumption during peak hours, is becoming essential to maintain the stability of the power grid and reduce costs .

Using QDual3 modules, manufacturers can design a PV inverter and ESS that produce more power in the same size system, enabling more efficient energy management and storage capabilities, enabling more seamless integration of solar energy into the grid.

The modules also mitigate solar intermittency by storing excess energy in the ESS, ensuring a reliable and consistent energy flow. For large systems, modules can be connected in parallel to increase the output power to several MW, and compared to traditional 600 A modular solutions, 800 A QDual3 can significantly reduce the number of modules, greatly simplifying design complexity and lowering system costs.

The QDual3 IGBT module has an 800A half-bridge configuration that integrates the latest Field Stop Gen7 trench IGBT transistor and diode technology using Onsemi’s advanced packaging techniques to reduce switching and conduction losses. With FS7 technology, the die size is reduced by 30%, allowing more dies to be used per module, increasing the power density to enable maximum current carrying capacity of 800 A or more.

With IGBT Vce(sat) as low as 1.75V (1750°C) and low Eoff, the 800A QDual3 module dissipates 10% less power loss than the next best alternative. The modules also meet the rigorous standards required in automotive applications.

“The increasing electrification of commercial fleets such as trucks and buses and the demand for renewable energy sources require solutions that can produce, store and distribute energy more efficiently. Transmitting energy from renewable sources to the grid, storage systems and downstream loads with the lowest possible power losses is increasingly important,” said Sravan Vanaparthy, Vice President, Industrial Power Division, Power Solutions Group, onsemi. “With industry-standard pinout and performance, QDual3 enables power electronics designers to plug and play these modules to instantly increase the performance of their systems.”
