Technology

The beating heart of our qIPM platform. A compact power module that switches at megahertz speeds. Stack them to scale in voltage and power.

Why it matters.

01
Stack to scale

Add modules to reach the voltage and power an application needs, rather than designing a new converter.

02
One cell, three markets

The same power cell drives motors, transforms robotics and powers AI racks.

03
Up to 5× the power density

In qIPM-DC, far more power than today's converters in the same space.

04
Faster to market

One standard cell across products: less inventory to manage, simpler and faster design cycles, and a quicker time to market.

Inside the module.

QPT's qDrive gate drivers switch third-party GaN transistors. qHarvest recovers the energy that fast switching would otherwise waste, and ZEST isolates one side from the other. Control comes in and sensing goes out to qControl and qSense, outside the module.

qMicroModule, A high-voltage motor example. Vin and GND in. On each side, four qDrive (gate driver) chips each switch a GaN transistor (third-party); each pair feeds a qHarvest (energy harvesting). Both sides meet at ZEST (isolation transformer). Vout and GND out. Control in, Sense out.
01
Gallium nitride

Third-party GaN power devices, robust and switching at megahertz speeds.

02
qDrive

QPT's own gate-driver chip, fast and clean enough for 1 MHz.

03
qHarvest

QPT's own. Recovers the energy fast switching would otherwise waste as heat.

04
ZEST

QPT's own isolation transformer, small enough to sit inside the module.

Controlling the module.

qMicroModule converts the power. QPT's qControl and qSense chips control and monitor it from outside the module, and together they make qIPM: the complete 1 MHz power stage for motor drives and AI data-centre power.
