Traditional way of applying ampere-second and voltage-second balances has commonly been adopted for calculating state variables of a converter. However, it becomes tedious and error prone when used with complicated topologies having many inductors and capacitors. Therefore, to simplify the circuit analysis, a reactive component elimination method has been proposed in this chapter for application to all converter topologies. To demonstrate, current and voltage stresses of a type of coupled inductor impedance source inverter have been determined using both traditional and proposed methods. Besides, the coupled inductor introduces the leakage inductance to the inverters and cause many problems during switching transient. Since the invert stage is coupled with the impedance stage in the impedance source inverters, it is very hard to describe the switching process clearly with traditional inverter models. Therefore, a novel model for the coupled inductor impedance source inverters is proposed in this chapter. The proposed model can be used to analyze the switching transient of the impedance source inverter. Furthermore, with the help of this model, it is easy to tell the power lost during the switching transient.
