In [ 8 ], the buck/boost circuit is integrated into a traditional single-phase full-bridge inverter by sharing the upper switch and the body diode of the lower switch in both bridge-legs, which effectively reduces the number of switching devices and improves the inverter efficiency.
Besides, there is only one switch operates at the high frequency state at the same time in the presented inverter, and the total high-frequency modulation time of all of the switches is only one power frequency cycle, which can reduce the switching times and leads to lower switching losses compared with other boost inverters.
Abstract: This paper proposed an integrated inverter to achieve voltage boosting and leakage current suppression. The proposed inverter is obtained by only adding two diodes to the existing bimodal inverter.
The switched-capacitor differential boost inverters studied in [ 9, 20] implement boost by doubling the voltage of the switched-capacitor network, and the bridge arm output is multi-level, which is beneficial to reduce the volume of output filters and the voltage stress of devices.
The differences in circuit type can directly affect the performance indexes of single-stage boost inverter in terms of efficiency, stress, ripple, volume and weight. The single-stage inverters proposed in [ 4 - 6] are based on boost circuits.
