A Family of Single-Phase Single-Stage Boost Inverters

H-bridge inverter is a common topology used for single-phase applications. Due to its limited voltage gain, two-stage power conversion with front-end dc-dc converter usually adopted accommodate the low dc source voltage. Recently, single-stage boost inverters are gaining significant interest due their higher efficiency and compactness. This paper presents family of continuous current. By incorporation merely switch inductor first leg H-bridge, voltage-boosting 3-level generation can be simultaneously achieved within operation. All potential topologies using same number components derived. An extension generate five levels gain enhancement also proposed. The operation proposed thoroughly analyzed. Simulation experimental results presented verification.
