This paper proposes a new multirate analysis method which selects a proper numerical integration stepsize for each variable in analyzing a power electronic system which has a subcircuit with different rates. First a formulation technique of multirate circuit equations is derived. Then a rate classification technique is derived from the error estimation formula of the backward differentiation formulas (BDF). Further a stepsize adjustment technique at a break point is explained. Finally the proposed method is applied to a DC chopper, a DC-DC converter and a PWM inverter circuit which showed efficiency of the method
