This paper deals with stabilization of an idealtransformermodel (ITM) circuit, used as an interfacingalgorithm for hardware-in-the-loop simulations. The ITM allows for the distribution of simulation model computations over multiple processors or can be used in power hardware-in-the-loop simulations. When specific impedance conditions of the partitioned circuit are not met, this interfacingalgorithm becomes unstable. This paper first presents a new theoretical approach for representing the ITM interfacingalgorithm that is based on delay differential equations. With a stability analysis of the obtained time-delay system, a stabilization method is proposed, which increases the stability boundaries of the ITM algorithm. Simulation examples, including the scenario of a two-level inverter system, are provided.
