1. A method for predicting a steady state performance of a switched circuit having a first operating state and a second operating state, the method comprising: identifying a plurality of circuit components, each circuit component having at least one parameter; determining a first state transition matrix [A 1 ] and a second state transition matrix [A 2 ]; defining a first state sourcing matrix [B 1 ] and a second state sourcing matrix [B 2 ]; defining a first energy input matrix [E 1 ] for energy input to the switched circuit during the first state and a second energy input matrix [E 2 ] for energy input to the switched circuit during the second state; defining a first state equation and a second state equation as a function of a dwell time in the first state; equating the end condition of the first state to the starting condition of the second state and equating the end condition of the second state to the starting condition of first state; obtaining a starting condition; and predicting the steady state performance of the switched circuit as a function of the first and the second state equations and the starting condition.
