The closed -loop stability and the simulation accuracy are two paramount issues in power hardware -in -the -loop （HIL） simulation. In order to solve the issues, the stability analysis and accuracy evaluation based on system transfer function were proposed. Five different interface algorithms were described, and their respective characteristics with respect to the system stability were compared. Through Matlab/Simulink simulations, the mod- els of simple circuit digital simulation subsystem and physical tested system were established to simulate the stability and accuracy of the five interface algorithms offline. The results show the feasibility of damping and impedance method is higher than that of others in specific application.
