It is important to get a steady-state operation of a power electronic circuit for its design. The shooting method, which is one of the steady-state analysis methods, solves a boundary value condition which equates initial values to final values after one-period transient. This paper proposes how to process the analysis in parallel by using a Parallel Virtual Machine (PVM3) system. In particular, the multiple shooting method (MSM) which divides the shooting time into subsections is suitable because it can parallel numerical processes for the divided shooting times by using multiple CPU units independently. This parallel method is applied to converter examples which are processes by PVM3. The computed results are investigated for their convergence and CPU times to check their parallel effects. According to the MSM algorithm, CPU times are reduced almost to one-fifth by using five computer units from a PVM3 system example.
