Inverter team at Karma Automotive provides in-house development of power inverters (HW and SW) for world-class Karma EVs. As a main step in inverter SW and HW development, we developed a Hardware-in-the-Loop unit and an inverter fast prototyping tool. The Hardware-in-the-Loop unit is a main tool for SW development task, and it is now being extended to include SW verification tests, too. On the other hand, the fast prototyping tool is an essential tool to facilitate the implementation of inverter HW for the future EV platforms. This unit also provides a powerful tool for development of SW application layer with the possibility of high frequency sampling and monitoring.
The presentation file will discuss the structure of Hardware-in-the-Loop unit (power stage and monitoring) using OP5700 platform and its interaction with control board via CAN bus. It also covers the CAN unit of OP5700 platform to be used for implementation of automatic verification tests. As another discussion, the development of the fast prototyping tool (including motor control algorithm, protection, diagnostics, and CAN communication) using OP4510 platform will be discussed. The testing of the fast prototyping unit with the hardware-in-the-loop unit will be also presented.

Also he was overseeing the e-drive system software development and control algorithms for traction derive and range extender.
Full vehicle simulation models are needed to assess attributes such as fuel economy and performance. In this session, you will learn how MathWorks automotive modeling tools can be used for powertrain selection studies. Specifically, we will examine the impact of adding an electric motor at different locations along the driveline (e.g., pre- or post-transmission). In order to make a fair comparison between alternatives, an optimal supervisory control strategy known as ECMS (Equivalent Consumption Minimization Strategy) is applied. With these closed-loop models, we can quantify the performance / fuel economy tradeoffs for the architectures under consideration and determine an optimal powertrain selection.

The key reasons for using digital control in power electronics are
• Lower cost
• Complex control requirements
• Configurability
• Optimizing for operating point variation
• Control adaption
• Management of the non-linearity of the converter
• The ability to tune the switching times precisely to minimize the power loss and maximize the efficiency.
The advantages of digital control of power electronics bring with them challenges. Dealing with these challenges before they expose problems is the key to fast product delivery and reliable and robust operation. The challenges include
• Limited Number of Bits
• Sampling and limited bandwidth
• Processing Delay
• Producing and maintaining high quality software code
The presentation explores the detail of these challenges and presents tools, methods and quality approaches to address them.

Presentation:
In this presentation, we will discuss about using eHS to develop NI controller for DC Fast Charging System (DCFCS) including a local battery storage system.
The key challenge for fast EV charging is the limitations of the existing power grid infrastructure. Fast charging requires a large amount of energy in a very short time, and the distribution power grid was not designed for this. Therefore, the DCFCS includes a battery storage system to reduce the impact of DCFCS that is incurred during charging. Power electronics converter configuration, its controller design and development of a 60-kW prototype will be discussed in this presentation.
