Simulation tools have been extensively used for the design and improvement of electrical systems for decades. The evolution of simulation tools has progressed dramatically in recent years with the advancement in computing technologies. The present trend in simulation is Real time Simulation where the computer model runs at the same rate as the actual physical time. The only reason to conduct Real-time Simulation is to connect real hardware to the simulated model. This is where the importance of hardware in the loop simulation emerges where the virtual plant model is controlled using a real controller. Synchronization of external PWM signals with the simulation time step of the virtual plant model is the main concern while conducting HIL simulation of Power Electronic systems. In this work a time compensation algorithm is developed to deduce the accurate switching instant of the control signals. timecompensation hardware is implemented using FPGA and accurate switching, instant is incorporated into the simulation process with the help of time compensated libraries for switching elements. The algorithm is tested by giving PWM signals from external controllers to a virtual buck converter model simulated inside Full Spectrum Simulator (FSS). Results obtained by enabling and disabling the algorithm are analyzed thoroughly and is finding that timecompensation greatly helps to obtain maximum accuracy while conducting HIL simulation.
