QPT Ltd Information

Electric motors use up to 45% of the world’s energy. QPT's solution is designed to reduce this by 10% and reduce energy consumption and CO2 emissions. THE PROBLEM The speed of an electric motor is controlled by a Variable Frequency Drives (VFDs). The faster the transistors in the VFDs can switch, the more energy is saved. GaN (Gallium Nitride) transistors can switch at much faster speeds than silicon or SiC (silicon carbide), but there are major Electromagnetic and thermal issues if driven at more than 100kHz. This limits high-speed GaN transistors to lower power applications. To our knowledge, no company has enabled the use of GaN transistors in the critical area of driving electric motors. THE SOLUTION By solving GaN’s electromagnetic and heating issues at high-speed and high-voltage, our solution is over 20x faster than even the current, next-generation silicon carbide-based solutions, and can deliver unprecedented power savings. Faster switching also means much greater power density, meaning a smaller and lighter solution, providing additional efficiency in EVs, or simpler installation and cabling solutions in industrial applications, amongst other benefits. High-frequency VFDs also don’t need an expensive filter between the VFD and the electric motor, meaning our solution can save costs for manufacturers and customers.
