Abstract
This chapter describes how nodal analysis can be used to determine the currents through stiff branches (that have a very low time constant) in the circuit. With the example of a simple buck converter, the chapter describes how loop analysis is insufficient in determining the conduction of power devices during switching events. The chapter then describes how nodal analysis can be used effectively in determining how power devices conduct and the transfer of current from one device to another. The chapter introduces the concept of events and how the matrix equations for the circuit will be constant until an event occurs. The chapter finally describes the logical flow of processes in the simulator as it performs loop analysis and nodal analysis one after the other.
