Abstract
The simplified topology for the high-frequency ac (HFAC) power distribution method with a multi-level inverter (MLI) hybrid switched capacitor (SC) is introduced. Capacitors, switches, diodes, and DC sources are among the components that are reduced in the designed MIB-MLI (Multi Input Boosting Multi-level Inverter). Where asymmetric dc voltage sources are available, such as in renewable energy farm-based ac microgrids and current electric vehicle, this architecture is advantageous. The proposed inverter has the feature of self-balancing the capacitor voltages and voltage boosting by using the series-parallel conversion scheme. The quality of output power is increased when a dc source array is connected with the unidirectional switched converter. Moreover, if a major phase variation betwixt the output current along with the voltage is no more mandatory, multiple alive switches may be recouped with diodes. In the switched capacitor group ripple volatge is reciprocal to the output frequency, so the MIB-MLI is favorable for HFAC implementations. Also, this paper clarifies the operating theory of the complete network and switching condition covered by the sinusoidal pulse width modulation (SPWM) technique. Mathematical equation related to power loss and capacitor voltages are provided. The modeling and simulation results of the proposed seventeen-level (17-L) inverter are depicted in this paper. The findings have shown that the proposed inverter is superior at HFAC along with the power efficiency of the inverter is adequate with SPWM technique.
