Abstract
This chapter addresses the quasi-Z-source inverters (qZSI) with battery paralleling to C 2 for a PV system as an example. The dynamic model and the control method, including battery energy management, PV power maximum power point tracking (MPPT), and grid-tie synchronization, are presented. Similar methods can be performed with the Z-source inverters (ZSI) or when battery connecting to C 1 . Example simulations are demonstrated in different cases of battery state of charge. The energy storage battery integrated ZSI/qZSI deals with power management among the renewable energy sources, grid, and battery in single-stage power conversion, without the extra dc-dc battery charging converter, providing simple topology and control. Its small-signal model was built to design the controller, especially battery current and energy management control. Simulation results were illustrated for different cases of battery state of charge. The solution is also inheritable to the other derived impedance topologies with battery paralleling to the capacitors.
