Two-level and three-level inverters are types of power electronic systems designed to convert direct current (DC) into alternating current (AC). They are commonly used in various applications such as UPS, electric vehicles, renewable energy systems, and motor drives. Here are the key differences between these two types of inverters: Voltage Levels
Introduction The three-phase two-level (3P2L) inverter has salient features of simple structure, superior output waveforms, and low system cost . Thus, it has been extensively used in varieties of industry applications, such as renewable energy system, ac motor drive system, power quality control, etc.
However, most 3-phase loads are connected in wye or delta, placing constraints on the instantaneous voltages that can be applied to each branch of the load. For the wye connection, all the “negative” terminals of the inverter outputs are tied together, and for the detla connection, the inverter output terminals are cascaded in a ring.
Another issue of the three-phase inverter is the common-mode voltage (CMV), which is excited by the switching behavior of the power semiconductor devices .
They are commonly used in various applications such as UPS, electric vehicles, renewable energy systems, and motor drives. Here are the key differences between these two types of inverters: Voltage Levels Two-Level Inverter: This type of inverter has two voltage levels at the output.
The three-phase PV grid-connected inverter was designed based on the LQR method, where the tracking error was adjusted to zero through integration (Al-Abri et al., 2024). The disturbance rejection ability of the PV GCI was improved by designing the linear state inaccuracy feedback control policy (Zhou et al., 2021).
