Dual 400V – 2x280kVA boost EV Motor Controller
DDM400V640A1 is part of a modular inverter structure family suitable for a wide range of automotive applications, integrating functionalities available on two separate inverters into a single unit.
It is a dual inverter solution for Electric Vehicles (EV), but it may be adopted as well in Hybrid Electric Vehicles (HEV), in Plug-in Hybrid Electric Vehicles (PHEV), or in Full-Electric Vehicles (FEV).
It is designed according to ISO26262 safety standard guidelines, having in mind specifically electric vehicles equipped with two 3-phase motors (up to 400V DC bus) for automotive applications (two 3-phase motors (including PMSM, TFM, AFM) or single 6-phases PMSM motor are supported).
This unique integration and modularity significantly reduces cost, space and cable connections while increasing quality and reliability compared with traditional multi ECU solutions.
Motor support
Traction inverter for 3-phase electric motors having: DC-Link: 400V (nominal), DC-Link Range: 350V – 450V, Current: 2x300A (rms continuous), 620A (rms boost), Power: 2x130kVA (continuous), 2x280kVA (boost); Power density: 76kVA/liter; Specific Power: 50kVA/Kg, Operating ambient temperature: -40…+105°C, Liquid coolant temperature: 65 °C.
Support for multiple motor types (eg.: BLDC, PMSM, TFM, AFM). Full access motor control parameters and torque mapping. Flexible support for position sensors and interfaces including digital Hall sensors, Encoder, SSI and analog Sin/Cos sensors. Support for motor temperature sensors.
Easy motor specific adaption independently of motor manufacturer. In case you do not have access to the detailed technical motor specification, I&M offers to characterize the motor for you on our in-house test bench.
High Efficiency Power Electronics and Motor Algorithms
“Field Oriented Control“ (FOC) or “Direct Flux Vector Control” (DFVC) control alghoritms available. Highest performance and maximum torque under all operating conditions and speeds with “Full Field Weakening“ support. Up to 98% efficiency, that means increased vehicle range.
High energy efficiency due to recuperative breaking option. Advanced Pulse Width Modulation technology for efficient use of battery voltage, low motor harmonics, low torque ripple and minimized switching losses. Total Harmonics Distortion (THD) less than 2%..
