Electric motors use up to 45% of the world’s electricity
QPT's solution is designed to reduce this by 10% and reduce energy consumption and carbon emisions.
QPT’s “Intelligent Power Module” enables companies to develop motor drives that reduce losses by 80%, are up to 20x smaller than existing solutions, drive the motor with a sine wave, and significantly reduce system costs.
Finally unleashing the full potential of Gallium Nitride (GaN) transistors to power the world’s electric motors.
Watch our short overview of QPT’s technology
GaN - The future of efficient power electronics
Gallium Nitride (GaN) transistors are the future of power electronics as, theoretically, they offer significant power savings.
But GaN transistors have to be switched at 1 to 2 nanoseconds in order to operate efficiently at super high frequencies of up to 20MHz, to deliver efficiency benefits, the highest power density and enable a sine wave output to the motor.
This creates huge ElectroMagnetic Interference (EMI) and thermal issues.
Current solutions limit the potential of GaN
Companies that claim to have GaN solutions for high power, high voltage applications that use hard switching are using fixes or workarounds, such as variable slew rates, that throttle back the switching speed so that EMI is no longer an issue.
However, running at dramatically slower switching speeds negates the major power saving benefit that GaN has to offer. Thus, in reality, all current, high power GaN solutions are no better than existing Silicon Carbide (SiC) or Silicon-based alternatives.
Unleashing the full potential of GaN
QPT is the only company that can run GaN transistors efficiecntly at super high frequencies of up to 20MHz without EMI issues or overheating to really deliver the promised power savings of using GaN to drive the world’s electric motors.
Turnkey solution for existing systems
Our “Intelligent Power Module” - qIPM™ integrates high voltage GaN transistors packaged with our proprietary qDrive technology to achieve unparalleled (<2ns) switching speeds and a thermal design that allows the full power handling and ultimate efficiency of the transistor to be realised – for the first time! EMI is reduced to a whisper, making EMC qualification a breeze, instead of the nightmare that power engineers have with any previous high voltage GaN products.
Why this is important
For the sake of the planet, the world needs to cut back on its use of electrical energy and the main usage, at 45%, is by electrical motors*.
QPT is a cleantech company that is the first to devise, patent and build a new, much more energy-efficient ways to control electrical motors and slash the energy they need by up to 10%.
That means cutting the energy costs of running heat pumps, air conditioning systems, motors, electric vehicles, pumps, industrial equipment, robots and more.
