Abstract

A simplified dual-output boosting inverter topology is proposed in this study. It can be used to supply two independent single-phase loads from a low voltage DC-power supply with fewer active and passive components. The output voltages can be at the same frequency (common-frequency mode) or at different frequencies. The proposed topology uses a single inductor and capacitor to control both boosting and inversion operations. Compared to the traditional dual output inverter, the proposed topology reduces the active switches by 25%, while compared with the basic Z-source-based dual output inverter, it reduces the passive elements by 50%. The main drawback of this topology is the high-frequency current commutation problem of the forward diodes. A novel carrier-based pulse width modulation scheme to obtain sinusoidal output voltage with low input current ripples of the proposed topology is presented in this paper. Moreover, the presented topology's operating principles and mathematical analysis are introduced. Finally, a simulation study is presented to confirm the theoretical study.
