ASIL-D motor inverter prototype, developed with
Traction motor inverters convert DC battery voltage to multi-phase alternating current to drive the traction motors of electric and hybrid vehicles at the speed and acceleration demanded by the driver. Complex system control is required to monitor the motor’s state, sense the driving currents and reliably calculate and apply the desired torque energy.
NXP has partnered with
NXP plans to enable its customers to develop motor inverters based on the reference design platform with its system control components, enablement software and functional safety enablement while VEPCO Technologies will offer contract system engineering services for application and performance specific development on the platform.
“VEPCO Technologies’ deep motor drive knowledge and system experience together with NXP’s comprehensive automotive portfolio, functional safety products and tools offer our customers a compelling power inverter enablement platform,” said Dr.
According to NXP’s internal market estimates, 50 percent of all light vehicles sold worldwide will have some form of electric propulsion by 2030. These dynamics have created opportunities for new players who need partners with the automotive experience and the deep product and software portfolio needed to build cost-effective and efficient system solutions.
With more than 30 years of automotive experience and a rich automotive portfolio, NXP is well positioned to deliver the optimal performance, robust functional safety and power management required for the next generation of electric and hybrid vehicles.
“The ambitious road to vehicle electrification requires more than high-voltage power switches,” said
Traction Motor Inverter Systems
The control reference platform uses NXP automotive components to provide the required functional building blocks with an efficient system bill-of-materials (BoM) for both inverter control and drive operations and functional safety assurance.
- The new GD3100 isolated high-voltage gate driver IC that targets ISO 26262 ASIL D compliancy, with the following features:
- IGBT gate control redundancy and on/off state validation
- IGBT current and temp monitoring
- Analog and logic BIST
- Low and high voltage fail safe inputs.
- The MPC5775E microcontroller comes with integrated Motor Control capabilities and a software resolver implementation. Running PMSM sensorless field-oriented control uses < 10% of its computing capabilities leaving maximum bandwidth for all the safety features and complex driving strategies required for today’s EV and Hybrid Systems.
- The FS65xx is a highly robust power management safety System Basis Chip designed in multiple electrification applications, it includes ASIL- D ready fail-silent functional safety as a safety element out of context. It is part of a growing functional safety SBC family.
- Flexible and open system enablement provides customers tools for implementing their unique value-add energy management intellectual property and achieving their required levels of functional safety.
All motor inverter reference platform components are sampling today with first platform prototypes available 4Q18.
