    1.1 W LARA-100? The vision behind LARA-100 is to serve its users as a sort of a LAunch RAmp for Power Electronics control development, research and education. It emerged as the comprehensive answer to the permanent need for flexibility and comfortable performance in the PE laboratory.
  • Page 4 PERUN PowerDesk software suite. The role of LARA's Expansion Boards together with the PERUN PowerDesk SW is crucial in the concept of LARA-100 as the open and configurable platform. The role of Expansion Boards is:  interfacing with popular controllers such as Texas Instruments C2000 series ...
  • Page 5 (Bode plots, etc.) Very important fact is that PERUN PowerDesk can be utilized as an integral part of LARA-100 system as described above, but also it can be employed as a standalone software package. In this scenario a user can develop and test a control code on Texas Instruments C2000 controller using Perun PowerDesk for all mentioned purposes except for system configuration (since there is no LARA's hardware).
  • Page 6 PERUN PowerDesk tools proceed with evaluation, testing and re- design. LARA-100 with its HW and SW components presents well rounded and open re-configurable platform Figure 3 Frequently asked questions related to PERUN PowerDesk software suite: Can I use PERUN PowerDesk without LARA-100 hardware? The answer is yes.
