Abstract£ºIn allusion to the inconsistent initial conditions and the presence of impulsive voltages and currents at the switching instants, a numerical method based on the differential nodal equations is presented for analyzing piece-wise linear switched networks. This method can be used to accurately analyze the inconsistent initial conditions, impulses and transient of pieceª²wise linear switched networks according to impulsive balance principle by expressing 0- values of the dynamic elements with its auxiliary power supply. It is mainly used to confirm the topologic structure and 0+ initial conditions of the switched networks, and any approximate is not needed. The actual simulation indicates that using this method the quantity of calculation is very small, programming is simple, and high precision can be obtained.
