Our customer needed a high-power microwave source that could be used to generate a stable source of plasma, intended for disposing of solid waste materials. Discover how RFHIC’s GaN solid-state microwave solutions met their needs!
Our customer is a globally renowned company specializing in developing green plasma energy with the goals of industrializing plasma application technology. The company operates a world renowned plasma gasification plant generating up to 600kg of green hydrogen production per day to be reused for electricity and other forms of green gases.
Plasma energy can be used to dispose of not only of biomass but also harmful wastes and convert it into an efficient form of energy – which is commonly called syngas. The produced syngas can then be used to generate electricity, fuel combustion systems, and produce hydrogen.
The customer was currently using a 30kW magnetron system to generate plasma for their waste gasification system. Unfortunately, due to the magnetron’s short life span and high voltage characteristics the company was having major reliability and safety issues. In fact, the system would shut down every couple of hours due to a faulty magnetron head.
Also, having the magnetron supplier overseas made the maintenance process even more inefficient and costly.
Due to the system’s frequent shutdowns, the company was having trouble creating a reliable source of plasma – thus not being able to scale its production capabilities.
With this current pain point, the company was in dire need of a microwave solution that could generate and obtain plasma in a steady way while being able to withstand high temperatures.
RFHIC’s Proposed Solution
RFHIC offered a 12kW GaN solid state microwave generator (RIK2512K-40TG) operable from 2400 to 2500 MHz. The RIK2512K-40TG is a solid state-based microwave power source fabricated with RFHIC’s cutting edge gallium-nitride (GaN) on silicon-carbide (SiC) HEMT.
The RIK2512K-40TG provides a peak system efficiency of 54% and a VSWR of 6:1. The RIK2512K-40TG comes fully equipped with a 3-phase 380VAC power supply unit, a control module, and four SSPA shelves. (*External isolator and water load can be provided for additional costs)
Alternative to conventional magnetron type microwave power supplies, RFHIC’s RIK2512K-40TG allows precise digital controllability of the frequency, power, signal source and phase – using our proprietary Windows-based GUI software suite.
With its key features, it allowed our customer to generate and obtain a more uniform and deeper penetration plasma, allowing them to achieve higher volumes of waste in a shorter amount of time.
