Abstract：A novel three level dual buck half bridge inverter topology is researched in this paper. It reserves the advantages of two level dual buck half bridge inverter, which has no shoot-through problem and can operate in high switching frequency and high efficiency. Meanwhile, Compared to the two level configuration, it’s power devices have lower voltage stresses and it’s bridge output voltage has a reduced harmonic components, compared to the two level configuration. The operation principles of the circuit are explained in detail. A three status current hysteresis control strategy is proposed which realizes half cycle operation mode of the circuit. The experimental results of a 1kVA prototype verify that the proposed inverter has good performance.
