Power electronics systems are a class of dynamic systems that exhibit extremely fast dynamics due to high-frequency switching action of power electronics.Real time simulations of switching transitions require digital processor speeds and latencies that can actually be met with Intel based computer systems and with FPGA technologies making it 100 times faster than traditional computational methods to achieve high-resolution HIL for power electronics.

Hardware-in-the-Loop simulation for power systems is the major technology used for easy development and expansion of the actual simulation model by harnessing all the power of simulink with user friendly IDE.VTCDP/VTPDP is an integrated system which provide hardware platform to do HIL (hardware in loop simulation) with the use of user friendly graphical IDE (Integrated development environment) running on a real time operating system QNX. It also allows one to run and test all the control/protection/load flow algorithms required without the need of a test power electronics system to reduce development cycle, increase efficiency ,and improve reliability and safety of these systems for large number of applications.
