This paper presents all the possible steady states of the tapped-inductor single-stage boost inverter proposed. It is shown that, in addition to the desired three steady states, an operating cycle can contain another four abnormal states that do not contribute to the power conversion process. These four states can be avoided by selecting suitable value of the capacitors and inductors. By using the equations derived from the steady-state analysis, this paper also presents guidelines to design the impedance network accurately for the case when the inverter is operated only in the desired active and shoot-through states. The proposed design method can also be used to estimate the critical values of capacitance and inductance, in order to avoid those four states appearing during the operating cycle. Experiments are used to verify the design method and to demonstrate the appearance of the four states when the capacitors and inductors are smaller than their critical values.
