Abstract：For the closing RC network, the parameters can't be detected directly and its identification relies on response of port. For the existed equivalent RC network, limited by physical constraints, it is difficult to establish the power source model because stimulate signal on port varies randomly. This paper proposes an parameters identification method relying on the zero-input response. This method analyses the relationship between parameters of RC network and time constant in zero-input response without concerning of stimulate signal and get the conclusion that the parameters cannot be identified in one situation. Then, a method cascading one-order RC network is proposed to get different constraint equations about RC parameters under different RC network. Solving two constraint equations of RC network can identify RC parameters. Simulations and experiments are tested and verified on a two-order Cauer I type network which used to be identified as an example in this paper. The results show that this method can identify RC parameter accurately. Then, applying this method in insulated-gate bipolar transistor (IGBT) module also gets the accurate results.
