Magnetically Coupled Impedance-Source Inverters

IEEE Transactions on Industry Applications, 2012
Z-source inverters are a new class of inverters proposed with output voltage or current buck-boost ability. Despite their general attractiveness, there are some present limitations faced by existing Z-source inverters, most of which are linked to their requirement for low modulation ratio at high input-to-output gain and the presence of an impedance ...

Embedded active impedance source inverter: Analysis and implementation

International Journal of Circuit Theory and Applications, 2022
Abstract In this paper, a new active impedance source inverter with a suitable control method based on the pulse‐width modulation (PWM) technique is proposed. Based on the proposed control method, the analysis of the proposed inverter in different operating modes is given, and its boost factor is calculated.

Application of Impedance Source Inverters

2020
Impedance source inverters have attracted considerable attention in power decoupling, photovoltaic/wind power generation, and motor drive in recent years, because they can obtain high step-up boost ratio in a single stage by introducing an impedance network and special modulation strategy.

Impedance Source Inverters Analysis

2020
Traditional way of applying ampere-second and voltage-second balances has commonly been adopted for calculating state variables of a converter. However, it becomes tedious and error prone when used with complicated topologies having many inductors and capacitors.
