| Research Abstract |
This study developed accurate and efficient simulation methods of power conversion systems. It consists of two processes ; one is the modeling process and the other is the simulation process. For the former, a reduced-order model synthesis method is developed and it extracts a lumped parameter equivalent circuit for a frequency-dependent complex component with a given degree of freedom. It has a special feature that it can synthesize the circuit only with the positive values of elements. It is validated experimentally by PE system modeling examples. For the latter, a circuit partitioning method and a steady-state periodic analysis method are developed and they can analyze a PE system accurately and efficiently. They can analyze the system faster by applying the proposed parallel algorithms. The simulated examples are validated experimentally.
