IVd3

400V dual inverter purpose-built for Punch DHT hybrid systems. Controls P1 and P3 motors simultaneously in a single compact unit, with 20% higher power density and 20% volume reduction versus the previous generation.

Two motors. One unit. Up to 35% fuel savings in full hybrid and PHEV applications.

The P3 motor control covers a scalable power range of 80–180kW with 420 Arms peak current and efficiency reaching 99%. Purpose-built for the primary drive motor in Punch DHT systems.

The P1 motor control covers 50–100kW with peak current of 310 Arms and efficiency of 98.5%. Both channels run on the same unified AutoSAR 4.2.2 software platform — with integrated cybersecurity, FOTA, and ASIL-D capable functional safety. An electromagnetic clutch is included in the unit, coupling power without a complex hydraulic system. The DC-link capacitor is 36% smaller than the previous generation, and the current sensor is integrated directly onto the board — reducing size, external component count, and cost.

Target Applications

The IVd3 is designed for full hybrid and PHEV passenger car platforms. It is purpose-built for integration with Punch DHT120 and DHT150 systems, and is also compatible with other DHT architectures requiring dual inverter motor control.

Configurations

DHT120 compatible — P1 power range 50–100kW, P3 power range 80–180kW

DHT150 compatible — same dual inverter platform, scaled for higher torque DHT applications
ASIL-D capable — highest automotive functional safety integrity for hybrid motor control

Unified SW platform — same AutoSAR 4.2.2 architecture across all five inverter families

What makes our IV4 different

Dual motor, one unit

P1 and P3 motor control integrated in a single housing — 20% higher power density and 20% smaller than the previous generation through innovative power switch design.

No hydraulic system needed

The integrated electromagnetic clutch couples power between motors and drivetrain without a complex hydraulic system — fewer components, simpler architecture, lower cost.

ASIL-D capable

Highest automotive functional safety integrity level for hybrid motor control. ISO 26262 compliant with full cybersecurity per ISO 21434.
